Yuasa-Kawada J, Kinoshita-Kawada M, Hiramoto M, Yamagishi S, Mishima T, Yasunaga S, Tsuboi Y, Hattori N, Wu JY. Neuronal guidance signaling in neurodegenerative diseases: Key regulators that function at neuron-glia and neuroimmune interfaces. Neural Regen Res 2026; 21:612-635. [PMID: 39995079 DOI: 10.4103/nrr.nrr-d-24-01330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2024] [Accepted: 01/27/2025] [Indexed: 02/26/2025] Open
Abstract
The nervous system processes a vast amount of information, performing computations that underlie perception, cognition, and behavior. During development, neuronal guidance genes, which encode extracellular cues, their receptors, and downstream signal transducers, organize neural wiring to generate the complex architecture of the nervous system. It is now evident that many of these neuroguidance cues and their receptors are active during development and are also expressed in the adult nervous system. This suggests that neuronal guidance pathways are critical not only for neural wiring but also for ongoing function and maintenance of the mature nervous system. Supporting this view, these pathways continue to regulate synaptic connectivity, plasticity, and remodeling, and overall brain homeostasis throughout adulthood. Genetic and transcriptomic analyses have further revealed many neuronal guidance genes to be associated with a wide range of neurodegenerative and neuropsychiatric disorders. Although the precise mechanisms by which aberrant neuronal guidance signaling drives the pathogenesis of these diseases remain to be clarified, emerging evidence points to several common themes, including dysfunction in neurons, microglia, astrocytes, and endothelial cells, along with dysregulation of neuron-microglia-astrocyte, neuroimmune, and neurovascular interactions. In this review, we explore recent advances in understanding the molecular and cellular mechanisms by which aberrant neuronal guidance signaling contributes to disease pathogenesis through altered cell-cell interactions. For instance, recent studies have unveiled two distinct semaphorin-plexin signaling pathways that affect microglial activation and neuroinflammation. We discuss the challenges ahead, along with the therapeutic potentials of targeting neuronal guidance pathways for treating neurodegenerative diseases. Particular focus is placed on how neuronal guidance mechanisms control neuron-glia and neuroimmune interactions and modulate microglial function under physiological and pathological conditions. Specifically, we examine the crosstalk between neuronal guidance signaling and TREM2, a master regulator of microglial function, in the context of pathogenic protein aggregates. It is well-established that age is a major risk factor for neurodegeneration. Future research should address how aging and neuronal guidance signaling interact to influence an individual's susceptibility to various late-onset neurological diseases and how the progression of these diseases could be therapeutically blocked by targeting neuronal guidance pathways.

Abstract
Lactate serves as a key energy metabolite in the central nervous system, facilitating essential brain functions, including energy supply, signaling, and epigenetic modulation. Moreover, it links epigenetic modifications with metabolic reprogramming. Nonetheless, the specific mechanisms and roles of this connection in astrocytes remain unclear. Therefore, this review aims to explore the role and specific mechanisms of lactate in the metabolic reprogramming of astrocytes in the central nervous system. The close relationship between epigenetic modifications and metabolic reprogramming was discussed. Therapeutic strategies for targeting metabolic reprogramming in astrocytes in the central nervous system were also outlined to guide future research in central nervous system diseases. In the nervous system, lactate plays an essential role. However, its mechanism of action as a bridge between metabolic reprogramming and epigenetic modifications in the nervous system requires future investigation. The involvement of lactate in epigenetic modifications is currently a hot research topic, especially in lactylation modification, a key determinant in this process. Lactate also indirectly regulates various epigenetic modifications, such as N6-methyladenosine, acetylation, ubiquitination, and phosphorylation modifications, which are closely linked to several neurological disorders. In addition, exploring the clinical applications and potential therapeutic strategies of lactic acid provides new insights for future neurological disease treatments.

Abstract
Myelination, the continuous ensheathment of neuronal axons, is a lifelong process in the nervous system that is essential for the precise, temporospatial conduction of action potentials between neurons. Myelin also provides intercellular metabolic support to axons. Even minor disruptions in the integrity of myelin can impair neural performance and increase susceptibility to neurological diseases. In fact, myelin degeneration is a well-known neuropathological condition that is associated with normal aging and several neurodegenerative diseases, including multiple sclerosis and Alzheimer's disease. In the central nervous system, compact myelin sheaths are formed by fully mature oligodendrocytes. However, the entire oligodendrocyte lineage is susceptible to changes in the biological microenvironment and other risk factors that arise as the brain ages. In addition to their well-known role in action potential propagation, oligodendrocytes also provide intercellular metabolic support to axons by transferring energy metabolites and delivering exosomes. Therefore, myelin degeneration in the aging central nervous system is a significant contributor to the development of neurodegenerative diseases. Interventions that mitigate age-related myelin degeneration can improve neurological function in aging individuals. In this review, we investigate the changes in myelin that are associated with aging and their underlying mechanisms. We also discuss recent advances in understanding how myelin degeneration in the aging brain contributes to neurodegenerative diseases and explore the factors that can prevent, slow down, or even reverse age-related myelin degeneration. Future research will enhance our understanding of how reducing age-related myelin degeneration can be used as a therapeutic target for delaying or preventing neurodegenerative diseases.

JOURNAL/nrgr/04.03/01300535-202602000-00042/figure1/v/2025-05-05T160104Z/r/image-tiff The neuroinflammatory response mediated by microglial activation plays an important role in the secondary nerve injury of traumatic brain injury. The post-transcriptional modification of N 6 -methyladenosine is ubiquitous in the immune response of the central nervous system. The fat mass and obesity-related protein catalyzes the demethylation of N 6 -methyladenosine modifications on mRNA and is widely expressed in various tissues, participating in the regulation of multiple diseases' biological processes. However, the role of fat mass and obesity in microglial activation and the subsequent neuroinflammatory response after traumatic brain injury is unclear. In this study, we found that the expression of fat mass and obesity was significantly down-regulated in both lipopolysaccharide-treated BV2 cells and a traumatic brain injury mouse model. After fat mass and obesity interference, BV2 cells exhibited a pro-inflammatory phenotype as shown by the increased proportion of CD11b + /CD86 + cells and the secretion of pro-inflammatory cytokines. Fat mass and obesity-mediated N 6 -methyladenosine demethylation accelerated the degradation of ADAM17 mRNA, while silencing of fat mass and obesity enhanced the stability of ADAM17 mRNA. Therefore, down-regulation of fat mass and obesity expression leads to the abnormally high expression of ADAM17 in microglia. These results indicate that the activation of microglia and neuroinflammatory response regulated by fat mass and obesity-related N 6 -methyladenosine modification plays an important role in the pro-inflammatory process of secondary injury following traumatic brain injury.

Abstract
Glymphatic flow has been proposed to clear brain waste while we sleep. Cerebrospinal fluid moves from periarterial to perivenous spaces through the parenchyma, with subsequent cerebrospinal fluid drainage to dural lymphatics. Glymphatic disruption is associated with neurological conditions such as Alzheimer's disease and traumatic brain injury. Therefore, investigating its structure and function may improve understanding of pathophysiology. The recent controversy on whether glymphatic flow increases or decreases during sleep demonstrates that the glymphatic hypothesis remains contentious. However, discrepancies between different studies could be due to limitations of the specific techniques used and confounding factors. Here, we review the methods used to study glymphatic function and provide a toolkit from which researchers can choose. We conclude that tracer analysis has been useful, ex vivo techniques are unreliable, and in vivo imaging is still limited. Finally, we explore the potential for future methods and highlight the need for in vitro models, such as microfluidic devices, which may address technique limitations and enable progression of the field.

Abstract
Viruses adapt and modulate cellular pathways to allow their replication in host cells. The catabolic pathway of macroautophagy, for simplicity referred to as autophagy, is no exception. In this review, we discuss anti-viral functions of both autophagy and select components of the autophagy machinery, and how viruses have evaded them. Some viruses use the membrane remodeling ability of the autophagy machinery to build their replication compartments in the cytosol or efficiently egress from cells in a non-lytic fashion. Some of the autophagy machinery components and their remodeled membranes can even be found in viral particles as envelopes or single membranes around virus packages that protect them during spreading and transmission. Therefore, studies on autophagy regulation by viral infections can reveal functions of the autophagy machinery beyond lysosomal degradation of cytosolic constituents. Furthermore, they can also pinpoint molecular interactions with which the autophagy machinery can most efficiently be manipulated, and this may be relevant to develop effective disease treatments based on autophagy modulation.

Abstract
Age-related lung function decline is associated with small airway closure and gas trapping. The mechanisms which cause these changes are not fully understood. It has been suggested that COPD is caused by accelerated ageing. We have investigated pathological changes in the small airways during ageing, and evaluated whether the same or different processes exist in COPD. Histopathology and immunohistochemistry were used to examine small airway remodelling in healthy ageing, and then compare to age matched COPD patients. Ageing was associated with reduced alveolar attachment numbers (rho= -0.4 p = 0.049), increased epithelial area (rho = 0.5 p = 0.01), greater luminal narrowing due to epithelial expansion (rho = 0.5 p = 0.04) and increased alveolar septal neutrophils (rho = 0.6 p = 0.005). Compared to age matched controls, COPD small airways had 31% less alveolar attachments per airway (p = 0.02) and significantly more alveoalr septal neutrophils (p = 0.0007). Increased airway wall thickness was a feature of COPD but was not related to ageing in non-smokers. Alveolar attachment loss, accompanied by alveolar septum neutrophilic inflammation, and increased luminal narrowing due to epithelial expansion are major features of small airway remodelling during ageing. These features can explain the increased small airway narrowing and closure during ageing. Alveolar attachment loss is accelerated in COPD, likely due to increased neutrophilic inflammation.

Abstract
INTRODUCTION AND OBJECTIVES Post-tuberculosis lung disease (PTLD), as other chronic respiratory disorders, may have infectious complications; some of them can be prevented with vaccinations. So far, no document has discussed the potential role of vaccination in PTLD. Therefore, the objective of this review was to describe vaccination recommendations to prevent infections potentially capable of complicating PTLD. MATERIALS AND METHODS A non-systematic review of the literature was conducted. The following keywords were used: tuberculosis, vaccination, vaccines and PTLD. PubMed/MEDLINE and Embase were used as the search engine, focusing on English-language literature only. RESULTS We identified 9 vaccines potentially useful in PTLD. Influenza, pneumococcal and anti-COVID-19 vaccinations should be recommended. Patients with PTLD can also benefit from vaccination against shingles. Vaccination against pertussis is mainly relevant during childhood. Diphtheria, tetanus and measles vaccination are recommended for general population and should be considered in patients with PTLD not previously vaccinated. Tdap (Tetanus, diphtheria, and pertussis) booster should be repeated in every adult every ten years. Vaccination against BCG retains its importance during early childhood in countries where TB is endemic. CONCLUSIONS Vaccination deserves to be considered among the strategies to prevent and/or mitigate PTLD complications. Further evidence is necessary to better understand which vaccines have the greatest impact and cost-benefit.

Fritz AM, Smith AM. Poison, lies, war: A mixed methods content analysis of posts about COVID-19 vaccination on Gab Social. Hum Vaccin Immunother 2025; 21:2443999. [PMID: 39749427 DOI: 10.1080/21645515.2024.2443999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 12/04/2024] [Accepted: 12/14/2024] [Indexed: 01/04/2025] Open
Abstract
Recent surges in COVID-19 cases demonstrate the unabated transmissibility of this disease. Despite the ongoing threat of contagion, however, uptake of the COVID-19 vaccines, especially as booster doses, remains suboptimal among eligible adults and children in the United States, as reported by the World Health Organization (WHO). Public attitudes toward these vaccines remain balkanized, with some groups harboring ambivalence or even opposition to receiving inoculation. Given the challenges for public health posed by the current, and potentially, future pandemics, it is crucial to understand more about how laypersons discuss and frame the vaccination debate in informal, non- or minimally monitored spaces. Following their development, virtual groups were created to share stories about negative reactions to COVID-19 vaccines. Using a mixed methods approach, the present study analyzed a census of 368 posts on Gab Social that articulate users' attitudes toward COVID-19 vaccination. Our approach focused on the framing and themes reflected in the posts, along with specific concerns expressed by users. Key findings include the observation that Gab users frequently frame the COVID-19 vaccination decision as one of whether the vaccines do more harm than good (i.e. helping vs. hurting frame) and that adverse reactions to the COVID-19 vaccines are not being truthfully reported on by mainstream media. Moreover, posts often display an antagonistic "Us vs. Them" perspective that pits vaccine skeptics against adherents. Overall, Gab users expressed strong resistance to the vaccines and distrusted government-issued recommendations to vaccinate, yet valorized medical professionals who advocated for more research on the vaccines' safety. Through these investigations, we hope to derive insights that may inform COVID-19 vaccine promotion; accordingly, practical recommendations are suggested based on our findings.

Changes in PD-1 expression on T lymphocyte subsets and related immune indicators before and after definitive chemoradiotherapy for esophageal squamous cell carcinoma. Ann Med 2025; 57:2445190. [PMID: 39713872 DOI: 10.1080/07853890.2024.2445190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 07/29/2024] [Accepted: 11/30/2024] [Indexed: 12/24/2024] Open
Abstract
OBJECTIVE This study aimed to observe the dynamic changes in the expression of T lymphocytes, natural killer (NK) cells, and PD-1 in patients with first-diagnosed esophageal squamous cell carcinoma (ESCC) before and after chemoradiotherapy (CRT) and evaluate the impact of PD-1 expression in peripheral blood on the short-term outcome of patients with ESCC. PATIENTS AND METHODS Seventy-three patients with ESCC who were treated with definitive CRT were enrolled. Before and after CRT, flow cytometry was used to detect thePD-1 expression in the peripheral blood and related immune indicators. Peripheral blood from 10 healthy individuals was used as control. RESULTS The percentages of CD3+ (p = 0.018), CD4+ (p < 0.001), and CD8+ T cells (p < 0.001); NK cells (p = 0.009); and the CD4+/CD8+ ratio (p < 0.001), as well as PD-1+CD3+ (p < 0.001), PD-1+CD4+ (p < 0.001), and PD-1+CD8+ (p < 0.001) T cells, before CRT significantly differed from those in the post-CRT group. The percentages of PD-1+CD8+ T cells differed significantly between the radiotherapy alone and CRT groups (p < 0.05). PD-1 expression in CD3+, CD4+, and CD8+ T cells significantly decreased in patients achieving overall response rate (all p < 0.05). Compared with those in the incomplete response group, PD-1+CD8+ T cells significantly decreased in the CR group (p < 0.05). CONCLUSION CRT aggravated immunosuppression and increased PD-1 expression in T lymphocyte subsets in patients with ESCC, possibly related to the radiation field. PD-1 expression in T lymphocyte subsets can predict short-term outcomes in patients and provide a theoretical basis for the sequential application of PD-1 immunosuppressants after radiotherapy and chemotherapy.

Abstract
Herpes zoster (HZ) is increasingly common in the aging and is experienced by approximately one in three people in their lifetime. It is also relatively common in immune-compromised people. Acute HZ causes severe pain, reduced quality of life and severe complications, including prolonged pain, or postherpetic neuralgia (PHN), and ocular zoster, which may rarely progress to blindness. In severely immune-compromised people disseminated zoster may affect the brain and liver. A second-generation vaccine, the Recombinant Zoster Vaccine, consisting of recombinant viral glycoprotein E and the Adjuvant System 01 (AS01B), now offers >90% efficacy against HZ and associated complications in immune-competent people. Efficacy persists above 80% for 11 years. In severely immune-compromised patients, the vaccine is safe with efficacy and/or immunogenicity of 68-87%. There is also excellent immunogenicity for those on JAK inhibitors and corticosteroid therapy. The vaccine offers a paradigm for successful and durable immunization in the aging and immune-compromised.

Abstract
Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the LMNA gene. Although the hypothesis that NE perturbations from LMNA mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy (LMNA cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific Lmna deletion in vivo in the adult heart. We observed extensive NE perturbations prior to cardiac function deterioration with collateral damage in the perinuclear space. The Golgi is particularly affected, leading to cytoprotective stress responses that are likely disrupted by the progressive deterioration of the Golgi itself. In this review, we discuss the etiology of LMNA cardiomyopathy with perinuclear 'organelle trauma' as the nexus between NE damage and disease pathogenesis.

Piezo1 aggravates ischemia/reperfusion-induced acute kidney injury by Ca 2+-dependent calpain/HIF-1α/Notch signaling. Ren Fail 2025; 47:2447801. [PMID: 39780511 PMCID: PMC11721879 DOI: 10.1080/0886022x.2024.2447801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2024] [Revised: 12/08/2024] [Accepted: 12/23/2024] [Indexed: 01/11/2025] Open
Abstract
Macrophages play a vital role in the inflammation and repair processes of ischemia/reperfusion-induced acute kidney injury (IR-AKI). The mechanosensitive ion channel Piezo1 is significant in these inflammatory processes. However, the exact role of macrophage Piezo1 in IR-AKI is unknown. The main purpose of this study was to determine the role of macrophage Piezo1 in the injury and repair process in IR-AKI. Genetically modified mice with targeted knockout of Piezo1 in myeloid cells were established, and acute kidney injury was induced by bilateral renal vascular clamping surgery. Additionally, hypoxia treatment was performed on bone marrow-derived macrophages in vitro. Our data indicate that Piezo1 is upregulated in renal macrophages in mice with IR-AKI. Myeloid Piezo1 knockout provided protective effects in mice with IR-AKI. Mechanistically, the regulatory effects of Piezo1 on macrophages are at least partially linked to calpain signaling. Piezo1 activates Ca2+-dependent calpain signaling, which critically upregulates HIF-1α signaling. This key pathway subsequently influences the Notch and CCL2/CCR2 pathways, driving the polarization of M1 macrophages. In conclusion, our findings elucidate the biological functions of Piezo1 in renal macrophages, underscoring its role as a crucial mediator of acute kidney injury. Consequently, the genetic or pharmacological inhibition of Piezo1 presents a promising strategy for treating IR-AKI.

Abstract
This study examines how the alcohol metabolite acetaldehyde modulates mRNA methylation and expression of ethanol-metabolizing genes, uncovering its epigenetic role in ethanol metabolism. Using neuron-like (SH-SY5Y) and non-neuronal (SW620) cellular models, we examined the effects of chronic intermittent acetaldehyde (CIA) exposure and subsequent withdrawal (CIA+WD) on global RNA m6A modifications and the methylation and expression of three brain ethanol-metabolizing genes: CAT (catalase), CYP2E1 (cytochrome P450 2E1), and ALDH2 (aldehyde dehydrogenase 2). A 3-week CIA exposure, with or without 24-hour withdrawal, did not significantly alter global m6A methylation levels in either cell line. However, acetaldehyde exposure/withdrawal induced hypermethylation at the mRNA stop codon regions of ALDH2 (CIA: p = 0.002; CIA+WD: p = 0.055) and CAT (CIA: p = 0.077; CIA+WD: p = 0.036) in SH-SY5Y cells, but not in SW620 cells. Furthermore, ALDH2 mRNA expression was significantly upregulated in both cell types following exposure (SH-SY5Y: p = 0.073 [CIA] and 0.00002 [CIA+WD]; SW620: p = 0.0009 [CIA] and 0.00008 [CIA+WD]). In contrast, CYP2E1 mRNA methylation and the expression of CYP2E1 and CAT remained unchanged. These findings highlight the cell-specific epigenetic effects of acetaldehyde, particularly its role in modulating mRNA methylation and expression of ALDH2, a key enzyme in alcohol metabolism.

Abstract
Tumor-promoting inflammation significantly impacts cancer progression, and targeting inflammatory cytokines has emerged as a promising therapeutic approach in clinical trials. Interleukin (IL)-1α, a member of the IL-1 cytokine family, plays a crucial role in both inflammation and carcinogenesis. How IL-1α is secreted in the tumor microenvironment has been poorly understood, and we previously showed that calpain 1 cleaves pro-IL-1α for mature IL-1α secretion, which exacerbates hepatocellular carcinoma by recruiting myeloid-derived suppressor cells. In this study, we report that calpain 2 also modulates IL-1α secretion. Notably, a deficiency in calpain 2 resulted in enhanced hepatocellular carcinoma development within an IL-1α-enriched tumor microenvironment. Further investigations revealed that calpain 2 deficiency increased calpain 1 expression, implying a compensatory mechanism between the two calpains. Mechanistically, calpain 2 deficiency led to increased expression of FoxO3, which is a forkhead transcription factor that promotes calpain 1 expression. Collectively, these results suggest that calpain 2 modulates calpain 1 expression, and therefore IL-1α secretion through the induction of FoxO3, offering novel potential therapeutic targets for cancer treatment.

Abstract
Liver diseases are a significant global health issue, characterized by elevated levels of disorder and death. The substantial impact of ageing on liver diseases and their prognosis is evident. Multiple processes are involved in the ageing process, which ultimately leads to functional deterioration of this organ. The process of liver ageing not only renders the liver more susceptible to diseases but also compromises the integrity of other organs due to the liver's critical function in metabolism regulation. A growing body of research suggests that long non-coding RNAs (lncRNAs) play a significant role in the majority of pathophysiological pathways. They regulate gene expression through a variety of interactions with microRNAs (miRNAs), messenger RNAs (mRNAs), DNA, or proteins. LncRNAs exert a major influence on the progression of age-related liver diseases through the regulation of cell proliferation, necrosis, apoptosis, senescence, and metabolic reprogramming. A concise overview of the current understanding of lncRNAs and their potential impact on the development of age-related liver diseases will be provided in this mini-review.

Abstract
The field of antibody therapeutics is rapidly growing, with over 210 antibodies currently approved or in regulatory review and ~ 1,250 antibodies in clinical development. Antibodies are highly versatile molecules that, with strategic design of their antigen-binding domain (Fab) and the domain responsible for mediating effector functions (Fc), can be used in a wide range of therapeutic indications. Building on many years of progress, the biopharmaceutical industry is now advancing innovative research and development by exploring new targets and new formats and using antibody engineering to fine-tune functions tailored to specific disease requirements. In addition to considering the target and the disease context, however, the unique features of each therapeutic antibody trigger a diverse set of Fc-mediated effector functions. To avoid unexpected results on safety and efficacy outcomes during the later stages of the development process, it is crucial to measure the impact of antibody design on Fc-mediated effector function early in the antibody development process. Given the breadth of effector functions antibodies can deploy and the close interplay between the antibody Fab and Fc functional domains, it is important to conduct a comprehensive evaluation of Fc-mediated functions using an array of antigen-specific biophysical and cell-mediated functional assays. Here, we review antibody and Fc receptor properties that influence Fc effector functions and discuss their implications on development of safe and efficacious antibody therapeutics.

Abstract
Hepatitis B virus (HBV) DNA integration into the host cell genome is reportedly a major cause of liver cancer, and a source of hepatitis B surface antigen (HBsAg). High HBsAg levels can alter immune responses which therefore contributes to the progression of HBV-related disease. However, to what extent integration leads to the persistent circulating HBsAg is unclear. Here, we aimed to determine if the extent of HBV DNA integration is associated with the persistence of circulating HBsAg in people exposed to HBV. We established a digital droplet quantitative inverse PCR (dd-qinvPCR) method to quantify integrated HBV DNA in patients who had been exposed to HBV (anti-HBc positive and HBeAg-negative). Total DNA extracts from both liver resections (n = 32; 14 HBsAg-negative and 18 HBsAg-positive) and fine-needle aspirates (FNA, n = 10; 2 HBsAg-negative and 8 HBsAg-positive) were analysed. Using defined in vitro samples for assay establishment, we showed that dd-qinvPCR could detect integrations within an input of <80 cells. The frequency of integrated HBV DNA in those who had undergone HBsAg loss (n = 14, mean ± SD of 1.514 × 10-3 ± 1.839 × 10-3 integrations per cell) was on average 9-fold lower than those with active HBV infection (n = 18, 1.16 × 10-2 ± 1.76 × 10-2 integrations per cell; p = 0.0179). In conclusion, we have developed and validated a highly precise, sensitive and quantitative PCR-based method for the quantification of HBV integrations in clinical samples. Natural clearance of HBV is associated with fewer viral integrations. Future studies are needed to determine if dynamics of integrated HBV DNA can inform the development of curative therapies.

Abstract
The host restricted pathogens are competently dependent on their respective host for nutritional requirements. The bacterial metabolic pathways are surprisingly varied and remarkably flexible that in turn help them to successfully overcome competition and colonise their host. The metabolic adaptation plays pivotal role in bacterial pathogenesis. The understanding of host-pathogen metabolic crosstalk needs to be prioritized to decipher host-pathogen interactions. The review focuses on various aspects of host pathogen interactions that majorly involves adaptation of bacterial metabolism to counteract immune mechanisms by rectifying metabolic cues that provides pathogen the idea of different anatomical sites and the local physiology of the host. The key set of metabolites that are recognized as centre of competition between host and its pathogens are also briefly discussed. The factors that control the timely expression of virulence of bacterial pathogens is poorly understood. The perspective presented herein will facilitate us with a broader view of molecular mechanisms that modulates the expression of virulence factors in bacterial pathogens. The knowledge of crosslinked metabolic pathways of bacteria and their host will serve to develop novel potential therapeutics.

Investigating the predictive role of serum amyloid A and its association with immunological and coagulation biomarkers in recurrent pregnancy loss. Libyan J Med 2025; 20:2472492. [PMID: 40022649 PMCID: PMC11873918 DOI: 10.1080/19932820.2025.2472492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2024] [Accepted: 02/23/2025] [Indexed: 03/03/2025] Open
Abstract
To evaluate the predictive role of serum amyloid A (SAA) levels and their association with antiphospholipid antibodies (APA) and coagulation markers such as lupus anticoagulants (LA), anti-cardiolipin (ACA), protein C (PC) deficiency, protein S (PS) deficiency, and antithrombin III (ATIII) deficiency in recurrent pregnancy loss (RPL). This prospective case-control study comprised two groups: the study group (n = 88) included women with recurrent pregnancy loss at Mansoura University Hospital between January 2019 and December 2020, and the control group (n = 52) included women without obstetric or medical complications. Demographic, clinical, and laboratory data, including serum samples collected at 10 weeks of gestation, were collected from all participants. The study measured SAA levels, lupus anticoagulants, anti-cardiolipin, protein C, protein S, and antithrombin III levels. The SAA level was significantly elevated in the recurrent pregnancy loss group compared to that in the control group. Lupus anticoagulant positive, anti-cardiolipin positive Immunoglobulin M (IgM), and deficiencies in protein C, protein S, and antithrombin III were significantly observed in patients with RPL (p < 0.05). The SAA levels were significantly elevated in both LA-positive and ACA-positive IgM patients. The receiver operating characteristic (ROC) curve analysis demonstrated that at SAA > 24.8 for the prediction of recurrent pregnancy loss, sensitivity was 98.86%, and specificity was 92.31%. Positive and negative predictive values were 95.6% and 98.0%, respectively. The area under the curve = 0.971 (0.927-0.992). SAA is associated with recurrent pregnancy loss and may therefore serve as a potential predictor of this condition. The observed elevation in SAA levels could be primary or secondary to the inflammatory response that promotes thrombotic activity in RPL patients at risk of APA, Protein S, Protein C, and ATIII deficiencies. Implementing SAA screening during pregnancy may facilitate the identification of individuals who could potentially benefit from novel treatment strategies.

Abstract
Group A Streptococcus (GAS; Streptococcus pyogenes) is an important bacterial pathogen causing over 700 million superficial infections and around 500.000 deaths due to invasive disease or severe post-infection sequelae yearly. In spite of this major impact on society, there is currently no vaccine available against this bacterium. GAS strains can be separated into >250 distinct emm (M)-types, and protective immunity against GAS is believed to in part be dependent on type-specific antibodies. Here, we analyse the nature of protective immunity generated against GAS in a model of intraperitoneal immunization in mice. We demonstrate that multiple immunizations are required for the ability to survive a subsequent lethal challenge, and although significant levels of GAS-specific antibodies are produced, these are redundant for protection. Instead, our data show that the immunization-dependent protection in this model is induced in the absence of B and T cells and is accompanied by the induction of an altered acute cytokine profile upon subsequent infection, noticeable e.g. by the absence of classical pro-inflammatory cytokines and increased IFN-γ production. Further, the ability of immunized mice to survive a lethal infection is dependent on macrophages and the macrophage-activating cytokine IFN-γ. To our knowledge these findings are the first to suggest that GAS may have the ability to induce forms of trained innate immunity. Taken together, the current study proposes a novel role for the innate immune system in response to GAS infections that potentially could be leveraged for future development of effective vaccines.

Abstract
BACKGROUND Increasing evidence indicates that cancer stem cells (CSCs) and cancer stem-like cells form a special subpopulation of cells that are ubiquitous in tumors. These cells exhibit similar characteristics to those of normal stem cells in tissues; moreover, they are capable of self-renewal and differentiation, as well as high tumorigenicity and drug resistance. In prostate cancer (PCa), it is difficult to kill these cells using androgen signaling inhibitors and chemotherapy drugs. Consequently, the residual prostate cancer stem cells (PCSCs) mediate tumor recurrence and progression. OBJECTIVE This review aims to provide a comprehensive and up-to-date overview of PCSCs, with a particular emphasis on potential therapeutic strategies targeting these cells. METHODS After searching in PubMed and Embase databases using 'prostate cancer' and 'cancer stem cells' as keywords, studies related were compiled and examined. RESULTS In this review, we detail the origin and characteristics of PCSCs, introduce the regulatory pathways closely related to CSC survival and stemness maintenance, and discuss the link between epithelial-mesenchymal transition, tumor microenvironment and tumor stemness. Furthermore, we introduce the currently available therapeutic strategies targeting CSCs, including signaling pathway inhibitors, anti-apoptotic protein inhibitors, microRNAs, nanomedicine, and immunotherapy. Lastly, we summarize the limitations of current CSC research and mention future research directions. CONCLUSION A deeper understanding of the regulatory network and molecular markers of PCSCs could facilitate the development of novel therapeutic strategies targeting these cells. Previous preclinical studies have demonstrated the potential of this treatment approach. In the future, this may offer alternative treatment options for PCa patients.

Abstract
The nuclear envelope plays an indispensable role in the spatiotemporal organization of chromatin and transcriptional regulation during the intricate process of cell differentiation. This review outlines the distinct regulatory networks between nuclear envelope proteins, transcription factors and epigenetic modifications in controlling the expression of cell lineage-specific genes during differentiation. Nuclear lamina with its associated nuclear envelope proteins organize heterochromatin via Lamina-Associated Domains (LADs), proximal to the nuclear periphery. Since nuclear lamina is mechanosensitive, we critically examine the impact of extracellular forces on differentiation outcomes. The nuclear envelope is spanned by nuclear pore complexes which, in addition to their central role in transport, are associated with chromatin organization. Furthermore, mutations in the nuclear envelope proteins disrupt differentiation, resulting in developmental disorders. Investigating the underlying nuclear envelope controlled regulatory mechanisms of chromatin remodelling during lineage commitment will accelerate our fundamental understanding of developmental biology and regenerative medicine.

Abstract
Peritoneal dialysis (PD) can be used as renal replacement therapy when chronic kidney disease (CKD) progresses to end-stage renal disease. However, peritoneal fibrosis (PF) is a major cause of PD failure. Studies have demonstrated that PD fluid contains a significantly larger numbers of macrophages compared with the healthy individuals. During PD, macrophages can secrete cytokines to keep peritoneal tissue in sustained low-grade inflammation, and participate in the regulation of fibrosis-related signaling pathways, such as NF-κB, TGF-β/Smad, IL4/STAT6, and PI3K/AKT. A series of basic pathological changes occurs in peritoneal tissues, including epithelial mesenchymal transformation, overgeneration of neovasculature, and abnormal deposition of extracellular matrix. This review focuses on the role of macrophages in promoting PF during PD, summarizes the targets of macrophage-related inhibition of fibrosis, and provides new ideas for clinical research on delaying PF, maintaining the function and integrity of peritoneum, prolonging duration of PD as a renal replacement modality, and achieving longer survival in CKD patients.

Abstract
BACKGROUND Diamond-Blackfan anemia (DBA) is a congenital erythroid aplasia associated with physical anomalies and a predisposition to cancer. It is categorized as ribosomopathy related to heterozygous allelic variations in ribosomal protein (RP) genes. Pierre Robin sequence (PRS) is a rare and etiologically heterogeneous condition, defined by the clinical triad of micrognathia, glossoptosis, and cleft palate. METHODS AND RESULTS We present a 5-year-and-2-month-old Chinese boy diagnosed with DBA combined with RPS. He was born with micrognathia, cleft palate, and airway obstruction, resulting in neonatal asphyxia and feeding difficulties, which constitute the classic triad of PRS. Low-set ears, downslanted palpebral fissures, bilateral exotropia, a short neck, hypertelorism, a thenar muscle defect, and bilateral severe sensorineural hearing loss were also observed in the boy. His motor and speech development were significantly delayed. In addition, he was found to be granulocytopenic at birth and severely anemic at 2 years and 10 months of age. Whole exome sequencing of peripheral blood revealed a heterozygous mutation in the RPS28 gene (c.2T > C, p.Met1?), a novel pathogenic mutation in RPS28. RPS28 is one of the ribosomal protein (RP) genes, which may contribute to DBA-related phenotypes. The boy underwent HSCT from 9/10 HLA-matched donor and his neutrophil and hemoglobin levels returned to normal. CONCLUSION It is crucial to perform a genetic evaluation for syndromic bone marrow failure with congenital anomalies. A heterozygous mutation in the RPS28 gene (c.2T > C, p.Met1?) is a novel pathogenic mutation associated with DBA. HSCT is an effective treatment for hematological abnormalities in DBA.

Abstract
Microbiota transplant therapy is an emerging therapy for inflammatory bowel disease, but factors influencing its efficacy and mechanism remain poorly understood. In this narrative review, we outline key elements affecting therapeutic outcomes, including donor factors (such as age and patient relationship), recipient factors, control selection, and elements impacting engraftment and its correlation with clinical response. We also examine potential mechanisms through inflammatory bowel disease trials, focusing on the interplay between the microbiota, host, and immune system. Finally, we briefly explore potential future directions for microbiota transplant therapy and promising emerging treatments.

Abstract
Transforming growth factor-beta (TGF-β), a cytokine with near omnipresence, is an integral part of many vital cellular processes across the human body. The family includes three isoforms: Transforming growth factor-beta 1, 2, and 3. These cytokines play a significant role in the fibrosis cascade. Diabetic kidney disease (DKD), a major complication of diabetes, is increasing in prevalence daily, and the classical diagnosis of diabetes is based on the presence of albuminuria. The occurrence of nonalbuminuric DKD has provided new insight into the pathogenesis of this disease. The emphasis on multifactorial pathways involved in developing DKD has highlighted some markers associated with tissue fibrosis. In diabetic nephropathy, TGF-β is significantly involved in its pathology. Its presence in serum and urine means that it could be a diagnostic tool while its regulation provides potential therapeutic targets. Completely blocking TGF-β signaling could reach untargeted regions and cause unanticipated effects. This paper reviews the basic details of TGF-β as a cytokine, its role in DKD, and updates on research carried out to validate its candidacy.

Abstract
Cysteinyl leukotrienes (CysLTs), as potent lipid inflammatory mediators, play a pivotal role in systemic multi-organ inflammation and inter-organ communication through interactions with their receptors (CysLTRs). However, However, the function of CysLT3R is unclear and lacks a network of cross-organ metabolite interactions, and the clinical use of leukotriene receptor antagonists (LTRAs) has certain limitations. This review systematically synthesizes existing evidence and proposes future directions by clarifying receptor subtype specificity, optimizing targeted therapies, exploring CysLTs' applications in neuroimmunology, and elucidating the dual roles of CysLTs in chronic inflammation. It is indicated that CysLTs activate eosinophils, mast cells, and airway tuft cells, driving type 2 immune responses and mucus secretion in the lungs, thereby exacerbating respiratory diseases such as asthma. In the nervous system, CysLTs aggravate neurodegenerative disorders like cerebral ischemia and Alzheimer's disease by disrupting the blood-brain barrier, promoting glial activation, and inducing neuronal damage. In the gut, CysLTs regulate anti-helminth immunity via the tuft cell-ILC2 pathway and collaborate with prostaglandin D2 (PGD2) to modulate bile excretion and mucosal protection. Furthermore, CysLTs mediate communication through the gut-lung and gut-brain axes via metabolites such as succinate, contributing to cross-organ inflammatory regulation. In conclusion, this review highlights the complex roles of CysLTs in chronic inflammation, providing a theoretical foundation for precise intervention in multi-organ inflammatory diseases, which provides a theoretical framework for precision interventions in multi-organ inflammatory diseases and inspires interdisciplinary breakthroughs.

[PMID: 39763063 PMCID: PMC11721851 DOI: 10.1080/0886022x.2024.2449196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2024] [Revised: 12/03/2024] [Accepted: 12/29/2024] [Indexed: 01/12/2025] Open
Abstract
BACKGROUND Chronic kidney disease (CKD) is a prevalent chronic, non-communicable disease. The long-term health effects of dietary live microbes, primarily probiotics, on CKD patients remain insufficiently understood. This study aims to investigate the association between dietary intake of live microbes and long-term health outcomes among individuals with CKD. METHODS Utilizing the National Health and Nutrition Examination Survey (NHANES) database, Cox regression analysis assessed the association between medium and high categories dietary live microbe intake and health outcomes (all-cause, cardiovascular disease [CVD], and cancer-related mortality) in CKD patients. RESULTS A total of 3,646 CKD patients were enrolled. During the follow-up period, 1,593 all-cause mortality events were recorded, including 478 CVD deaths and 268 cancer deaths. In the fully adjusted model, compared to CKD patients in the lowest quartile (quartile 1) of live microbes intake, those in quartiles 3 and 4 exhibited a 20% and 26% reduced risk of all-cause mortality, with hazard ratios (HR) of 0.80 (95% confidence interval, CI: 0.69, 0.94) and 0.74 (95% CI: 0.62, 0.90), respectively. Additionally, compared to those with low live microbe intake (quartile 1), higher live microbe intake in quartile 4 was associated with a 37% reduction in the risk of CVD mortality for CKD patients, with an HR of 0.63 (95% CI: 0.45, 0.88). Consistent results were observed in subgroup and sensitivity analyses. A significant negative association was observed between live microbe intake and the risk of all-cause mortality as well as CVD mortality in the CKD population, with a p-value for trend < 0.05. CONCLUSION Our study indicated that high dietary live microbe intake could mitigate the risk of all-cause and CVD mortality in CKD patients. These findings support the inclusion of live microbes in dietary recommendations, highlighting their significant roles in CKD.

Development of a Caco-2-based intestinal mucosal model to study intestinal barrier properties and bacteria-mucus interactions. Gut Microbes 2025; 17:2434685. [PMID: 39714032 DOI: 10.1080/19490976.2024.2434685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 11/15/2024] [Accepted: 11/21/2024] [Indexed: 12/24/2024] Open
Abstract
The intestinal mucosal barrier is a dynamic system that allows nutrient uptake, stimulates healthy microbe-host interactions, and prevents invasion by pathogens. The mucosa consists of epithelial cells connected by cellular junctions that regulate the passage of nutrients covered by a mucus layer that plays an important role in host-microbiome interactions. Mimicking the intestinal mucosa for in vitro assays, particularly the generation of a mucus layer, has proven to be challenging. The intestinal cell-line Caco-2 is widely used in academic and industrial laboratories due to its capacity to polarize, form an apical brush border, and reproducibly grow into confluent cell layers in different culture systems. However, under normal culture conditions, Caco-2 cultures lack a mucus layer. Here, we demonstrate for the first time that Caco-2 cultures can form a robust mucus layer when cultured under air-liquid interface (ALI) conditions on Transwell inserts with addition of vasointestinal peptide (VIP) in the basolateral compartment. We demonstrate that unique gene clusters are regulated in response to ALI and VIP single stimuli, but the ALI-VIP combination treatment resulted in a significant upregulation of multiple mucin genes and proteins, including secreted MUC2 and transmembrane mucins MUC13 and MUC17. Expression of tight junction proteins was significantly altered in the ALI-VIP condition, leading to increased permeability to small molecules. Commensal Lactiplantibacillus plantarum bacteria closely associated with the Caco-2 mucus layer and differentially colonized the surface of the ALI cultures. Pathogenic Salmonella enterica were capable of invading beyond the mucus layer and brush border. In conclusion, Caco-2 ALI-VIP cultures provide an accessible and straightforward way to culture an in vitro intestinal mucosal model with improved biomimetic features. This novel in vitro intestinal model can facilitate studies into mucus and epithelial barrier functions and in-depth molecular characterization of pathogenic and commensal microbe-mucus interactions.

Abstract
BACKGROUND Diabetic kidney disease (DKD), characterized by mesangial fibrosis and renal dysfunction, is a major microvascular complication of diabetes. Studies have shown that miRNAs are closely related to the progression of DKD. Therefore, in this study, we aimed to explore whether miR-1225-3p can regulate Smad ubiquitin regulatory factor 2 (SMURF2)-mediated carbohydrate response element binding protein (ChREBP) ubiquitination through Rho GTPase-activating protein 5 (ARHGAP5) to affect fibrosis in DKD. METHODS DKD mice were established by intraperitoneally injecting streptozocin (STZ), and a DKD cell model was generated by culturing in media supplemented with 25 mmol/L glucose (high glucose, HG). StarBase was used to predict the target binding sites between miR-1225-3p and ARHGAP5, and a dual-luciferase reporter gene assay was used to verify this relationship. Western blotting, RT-qPCR, flow cytometry, immunoprecipitation, ELISAs, HE staining, and Masson staining were used to detect relevant indicators. RESULTS ARHGAP5 and SMURF2 expression was decreased, but ChREBP was highly expressed in the renal tissue of DKD mice and HG-induced mouse mesangial cells (MMCs). miR-1225-3p could target and regulate the transcription of ARHGAP5, and an association between ARHGAP5 and SMURF2 was revealed. miR-1225-3p facilitated fibrosis and oxidative stress in MCCs by inhibiting ARHGAP5. In addition, SMURF2 promoted the ubiquitination of HA-ChREBP, and miR-1225-3p facilitated fibrosis and oxidative stress by mediating the ARHGAP5/SMURF2-mediated ubiquitination of ChREBP in MCCs. Furthermore, the miR-1225-3p inhibitor inhibited fibrosis and inflammation in the renal tissues of DKD mice. CONCLUSION miR-1225-3p facilitates fibrosis and oxidative stress by mediating ARHGAP5/SMURF2-mediated ubiquitination of ChREBP.

Abstract
BACKGROUND Acinetobacter baumannii has become one of the most critical pathogens causing nosocomial pneumonia. Existing animal models of A. baumannii pneumonia are not relevant to the majority of critical care patients. We aimed to develop a novel model of secondary A. baumannii pneumonia in post-sepsis mice. METHODS A two-hit model of sepsis induced by cecal ligation and puncture followed by A. baumannii pneumonia on day 5 was established. In addition, the two-hit model was established in humanized mice. A period of 2 h of mechanical ventilation followed by observation was used in additional experiments. Lung histopathology, bacterial cultures, and cellular infiltration were analysed as well as markers of the inflammasome activity in vivo and ex vivo. RESULTS A. baumannii infection caused mortality and loss of body weight and temperature in post-sepsis mice. Increased lung bacterial burden and dissemination together with signs of enhanced inflammatory injury were observed in post-sepsis mice but not control mice that were challenged with A. baumannii. Post-sepsis mice were unable to mount inflammasome activation in response to secondary pneumonia to the level of control mice. Transfer of wild-type but not capsase-1 KO alveolar macrophages was able to restore the pulmonary protection against A. baumannii. Mechanical ventilation exacerbated the pathological response to pneumonia in post-sepsis mice but enhanced inflammasome signalling in non-sepsis mice with pneumonia. CONCLUSIONS We established a novel model of A. baumannii pneumonia that revealed sepsis-induced impairment of inflammasome activation in alveolar macrophages is critical for the control of secondary A. baumannii pneumonia.

Impact of carbohydrate timing on glucose metabolism and substrate oxidation following high-intensity evening aerobic exercise in athletes: a randomized controlled study. J Int Soc Sports Nutr 2025; 22:2494839. [PMID: 40259503 PMCID: PMC12016275 DOI: 10.1080/15502783.2025.2494839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Accepted: 04/10/2025] [Indexed: 04/23/2025] Open
Abstract
OBJECTIVE The study aimed to investigate the impact of nutrient timing in relation to evening exercise. Specifically, it examined the effects of pre- or post-exercise carbohydrate (CHO) ingestion on glucose metabolism, glucose regulation, and overall substrate oxidation in well-trained athletes during and after physical exercise (PE), spanning the nocturnal period and the subsequent morning. METHODS Ten male endurance cyclists participated in the study. The initial assessments included body composition measurements and an incremental cycle test to determine maximal oxygen uptake (V ˙ O2 max) and maximum power output (Wmax). Following this, participants underwent a control (rest previous day) oral glucose tolerance test (OGTT) and a familiarization exercise trial that had two objectives: (1) to establish the appropriate amount of CHO to use in the pre- or post-exercise drink during the experimental trials, and (2) to familiarize participants with the equipment and study protocol. In the three days prior to both the control and experimental trials, participants followed a standardized, individualized diet designed to meet their energy needs. During the experimental trials, participants completed two separate evening exercise sessions (50 min@70%Wmax + ~24 min time-trial (TT)) with either pre- or post-exercise CHO ingestion (253 ± 52 g), matching the CHO oxidized during exercise. The CHO drink and a volume-matched placebo (PLA) drink (containing no energy) were randomly assigned to be consumed two hours before and directly after the experimental exercise sessions. Post-exercise nocturnal interstitial glucose levels (24:00-06:00) were continuously monitored, and a 120-min OGTT was conducted the following morning to assess substrate oxidation rates and glucose control. RESULTS Pre-exercise CHO intake significantly lowered capillary glucose levels during steady-state exercise (mean difference 0.41 ± 0.27 mmol/L, p = 0.001) without affecting perceived exertion and TT-performance. No difference was observed in nocturnal glucose regulation (00:00-06:00) regardless of whether CHO was consumed before or after exercise. Post-exercise CHO ingestion reduced glucose tolerance during the OGTT compared to the iso-caloric pre-exercise CHO intake (mean difference 0.76 ± 0.21 mmol/L, p = 0.017). However, a post-exercise CHO intake improved respiratory exchange ratio/metabolic flexibility (MetF) significantly. Enhanced MetF during the first OGTT hour after post-exercise CHO ingestion resulted in 70% and 91% higher CHO oxidation compared to pre-exercise CHO and control, respectively (p ≤ 0.029). Average 120-min OGTT fat oxidation rates were higher with both pre- and post-exercise CHO ingestion compared to control (p ≤ 0.008), with no difference between pre- and post-exercise CHO intake. CONCLUSION Morning glucose tolerance was markedly reduced in healthy athletes when CHO was ingested after evening exercise. However, the observed improvements in MetF during the OGTT compared to placebo post-exercise suggest a potential for enhanced athletic performance in subsequent exercise sessions. This opens exciting possibilities for future research to explore whether enhanced MetF induced by CHO-timing can translate to improved athletic performance, offering new avenues for optimizing training and performance.

Abstract
This review was written to be included in the Special Collection 'Therapy Ultrasound: Medicine's Swiss Army Knife?' The purpose of this review is to provide basic presentation and interpretation of the fundamentals of hyperthermia biology, as it pertains to uses of therapeutic ultrasound. The fundamentals are presented but in the setting of a translational interpretation and a view toward the future. Subjects that require future research and development are highlighted. The effects of hyperthermia are time and temperature dependent. Because intra-tumoral temperatures are non-uniform in tumors, one has to account for differential biologic effects in different parts of a tumor that occur simultaneously during and after hyperthermia.

Abstract
To investigate the role of ALKBH3 in acute myeloid leukemia (AML), we constructed an animal model of xenotransplantation of AML. Our study demonstrated that ALKBH3-mediated m1A demethylation inhibits ferroptosis in KG-1 cells by increasing ATF4 expression, thus promoting the development of AML. These findings suggest that reducing ALKBH3 expression may be a potential strategy to mitigate AML progression. Background: Acute myeloid leukemia (AML) is characterized by the unrestrained proliferation of myeloid cells. Studies have shown that ALKBH3 is upregulated in most tumors, but the role of ALKBH3 in AML remains unclear.Methods: In this study, we investigated the function of ALKBH3 in AML cells (KG-1) by immunofluorescence, ELISA, flow cytometry, HE staining, and Western blotting.Results: Our results revealed that ALKBH3 is upregulated in AML and that the downregulation of ALKBH3 inhibited KG-1 cell proliferation and promoted cell apoptosis; at the same time, ALKBH3 upregulated ATF4 expression through m1A demethylation, and the knockdown of ATF4 resulted in increased ferrous iron content; TFR1, ACSL4, and PTGS2 expression; and ROS and MDA levels, whereas SOD and GSH levels and the expression levels of ATF4, SLC7A11, GPX4, and FTH1 decreased in KG-1 cells, thereby promoting ferroptosis. Mechanistically, ALKBH3-mediated m1A demethylation suppressed ferroptosis in KG-1 cells by increasing ATF4 expression, thereby promoting the development of AML.Conclusions: Our study indicated that reducing the expression of ALKBH3 might be a potential target for improving AML symptoms.

Abstract
Lumpy skin disease (LSD), which was confined to the Africa for many decades, has expanded its geographical distribution to numerous countries across Asia and Europe in recent years. The LSD virus (LSDV) is a relatively poorly studied virus. Its 151 Kb genome encodes 156 open reading frames (ORF); however, the exact number of the proteins encoded by the viral genome and their specific functions remain largely unknown. Arthropod vectors primarily transmit the LSDV mechanically, but the precise nature of these vectors in different regions and their role in transmission is not fully understood. Homologous live-attenuated vaccines prepared using LSDV have proven to be highly efficacious compared to heterologous vaccines based on sheep pox virus or goatpox virus, in protecting cattle against LSD. This review offers the latest insights into the molecular biology and transmission of LSDV and discusses the safety and efficacy of available vaccines, along with the challenges faced in controlling and eradicating the disease in endemic regions.

[PMID: 40268755 PMCID: PMC12020221 DOI: 10.1080/0886022x.2025.2492374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2025] [Revised: 03/24/2025] [Accepted: 04/07/2025] [Indexed: 04/25/2025] Open
Abstract
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common inherited kidney disease, characterized by the progressive development of multiple kidney cysts, leading to a gradual decline in kidney function. ADPKD is also the fourth leading cause of kidney failure (KF) in adults. In addition to kidney manifestations, ADPKD is associated with various extrarenal features, including liver cysts, cardiovascular abnormalities, intracranial aneurysms, and chronic pain with significant impact on patients' quality of life. While several disease-modifying agents have been tested in ADPKD, tolvaptan remains the only approved drug by the US Food and Drug Administration. The Mayo Imaging Classification is currently the most practical tool for predicting rate of kidney disease progression in ADPKD. This review provides a comprehensive overview of ADPKD, focusing on its genetics, pathophysiology, clinical presentation, management, and prognostic tools. Advances in diagnostic imaging and genetic testing have improved the early detection of ADPKD, allowing better classification of patients and prediction of KF. The review also discusses current therapeutic approaches to ADPKD, including tolvaptan, a vasopressin V2-receptor antagonist. Additionally, we address specific issues in children and pregnant individuals with ADPKD. Despite substantial progress in understanding ADPKD, there is a large need for additional effective treatments and prognostic markers to provide a more personalized care for these patients.

[PMID: 39962730 PMCID: PMC11837943 DOI: 10.1080/0886022x.2025.2460720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2024] [Revised: 12/31/2024] [Accepted: 01/24/2025] [Indexed: 02/21/2025] Open
Abstract
BACKGROUND In patients undergoing hemodialysis (HD), cardiovascular (CV) disease, particularly sudden cardiac death (SCD), is a major cause of mortality. Independent predictors of SCD include a prolonged QT interval on electrocardiography (ECG) and elevated levels of natriuretic peptides (NPs). This study explores the association between the QTc interval and NPs in HD patients. METHODS This cross-sectional study involved 207 HD patients, having a heart rate of 57 to 103 bpm, displaying sinus rhythm and no extrasystoles in ECG reports. Before the 2nd HD of the week, we conducted ECG and blood tests for atrial NP (ANP), brain NP (BNP), and N-terminal proBNP (NT-proBNP). The heart rate-corrected QT (QTc) was calculated using Bazett formula. Our analysis focused on the association between QTc and each NP, along with evaluating clinically relevant variables related to the QTc interval. RESULTS Univariate analyses indicated robust correlations among the NPs, with each NP significantly associated with the QTc interval. Multiple regression analyses of the three NPs revealed that NT-proBNP demonstrated the strongest predictive ability for the QTc interval. Independent predictors of prolonged QTc included lower corrected calcium (cCa) levels (p = 0.001), lower potassium (K) levels (p < 0.001), and higher log NT-proBNP (p = 0.004). CONCLUSION In HD patients, NT-proBNP shows a stronger link with the QTc interval than BNP or ANP. Integrating clinical management considering both QTc and log NT-proBNP levels might help reduce CV events. Additionally, vigilance regarding low K or cCa levels is recommended from the perspective of the QTc interval.

Abstract
This study investigated stress hyperglycemia ratio (SHR) for acute kidney injury (AKI) and clinical outcomes in intensive care unit (ICU). Key outcomes were AKI within 48 h after ICU admission, acute kidney disease (AKD), ICU mortality, 28-day mortality, 90-day mortality and 1-year mortality. The associations between SHR and outcomes was estimated via logistic regression, Cox proportional hazards regression, and restricted cubic spline (RCS) analyses. Subgroup analyses assessed the consistency of these associations. Totally 3,714 patients were included from the Medical Information Mart for Intensive Care IV. SHR was associated with an increased risk of AKI (ORadjusted 1.29 95%CI 1.05-1.59). Among AKI patients, SHR was associated with increased risks of AKD (ORadjusted 1.94 95%CI 1.57-2.39), ICU mortality (ORadjusted 2.31 95%CI 1.60-3.32), 28-day mortality (HRadjusted 1.39 95%CI 1.29-1.50), 90-day mortality (HRadjusted 1.37 95%CI 1.26-1.48), and 1-year mortality (HRadjusted 1.37 95%CI 1.27-1.47). RCS analysis revealed a linear relationship with AKI, a J-shaped relationship with AKD, and a U-shaped relationship with mortality. Subgroup analysis confirmed the consistency of relationship between SHR and AKI. SHR demonstrates significant associations with AKI incidence, and correlates with AKD progression/mortality in critically ill adult ICU patients, suggesting its potential as a risk stratification and prognostic tool for AKI management, though further prospective validation is required.

Abstract
PURPOSE This review aims to outline the crucial role of IL-36 signaling in inflammatory skin diseases and summarize the therapeutic potential of spesolimab. Our goal is to provide insights into the off-label applications of spesolimab and future directions for its use in treating other challenging skin diseases. MATERIALS AND METHODS We conducted a comprehensive literature search across PubMed, Embase, Web of Science, MEDLINE, Scopus, and the Cochrane Library to identify relevant studies. For RCTs, we additionally searched the ClinicalTrials.gov database. RESULTS In this review, we examine its off-label applications for conditions such as palmoplantar pustulosis, acrodermatitis continua of Hallopeau, hidradenitis suppurativa, pyoderma gangrenosum, and acute generalized exanthematous pustulosis. This review also explores the role of IL-36 in the pathophysiology of these disorders and discusses how spesolimab may address the limitations of current therapies for refractory cases. Randomized controlled trials and case reports are summarized to highlight the efficacy and tolerability of spesolimab across various inflammatory skin conditions. We highlight the challenges presented by the absence of standardized treatment guidelines and the need for larger clinical trials. CONCLUSIONS This review underscores the potential of spesolimab to enhance treatment strategies for inflammatory skin diseases.

Abstract
PURPOSE This study aimed to explore the characteristics of intestinal microflora polymorphism in postmenopausal women, and to determine the pathophysiological changes of gene polymorphism of intestinal flora and bone metabolism in postmenopausal osteoporosis (PMOP) patients. METHODS A total of 104 postmenopausal women with PMOP or normal bone density were included. Lifestyle, hip T-score, bone metabolism indexes (25(OH)D, PTH, β-CTX, PINP), intestinal mucous membrane barrier function (diamine oxidase, D-lactic acid, LPS), gene polymorphisms, and characteristics of gut microbiota were examined. RESULTS Women with PMOP had reduced physical activity, less dietary protein and calcium intake, lower levels of 25(OH)D, hip T-score, and BMD, but PMOP group had increased total energy and fat intake, and higher levels of PTH, β-CTX, diamine oxidase, D-lactic acid, and LPS (p < .05 for all), as compared with normal subjects. Analyses of the α- and β-diversity of fecal microbiota indicated remarkably differences in postmenopausal women with or without PMOP. In details, individuals with PMOP had increased abundances of some genera (e.g. Roseburia and Bacteroides), but decreased abundances of some genera (e.g. Streptococcus and Dorea). Furthermore, use of a random forest model based on differential abundant taxa and ROC analysis could efficiently identify women with PMOP in the present cohort (AUC = 0.93). CONCLUSION The incidence of PMOP was closely associated with fecal microbial compositions and intestinal functional changes. The present findings supported potential applications of gut microbiome analysis for early diagnosis of PMOP, and provided potential therapeutic targets.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a chronic autoimmune disease that primarily affects the axial joints. Immune cells play a key role in the pathogenesis of AS. This study integrated bioinformatics methods with experimental validation to explore the role of natural killer (NK) cells in AS. METHODS Two microarray datasets, GSE25101 and GSE73754, were selected, and the scRNA-seq data were obtained from GSE194315 and Liu's research. Differentially expressed genes (DEGs) and functional enrichment analysis were performed respectively. Weighted gene co-expression network analysis (WGCNA) was conducted to identify key modules of co-expressed genes and genes involved in NK cell function. The diagnostic value of the identified key genes was evaluated using ROC curves, logistic regression analysis, and a nomogram. Real-time PCR (RT-PCR) was used to quantified the expression of genes. Statistical analysis was conducted using the R software package, and a p-value of less than 0.05 was considered statistically significant. RESULTS Pathways enrichment analysis revealed the involvement of NK cell-mediated immune pathways and regulation of the innate immune response, indicating the crucial role of innate immunity, especially NK cells, in AS pathogenesis. The construction of a co-expression network revealed that the MElightyellow module was most relevant to the NK cell-mediated immune pathway. IL2RB, CD247, PLEKHF1, EOMES, S1PR5, FGFBP2 from the MElightyellow module were identified as key genes involved in NK cell-mediated immune response and served as potential diagnostic biomarkers for AS, with moderate to high diagnostic values based on AUC values. Further analysis using scRNA-seq profiling revealed the higher expression level of IL2RB, CD247, PLEKHF1, S1PR5, FGFBP2 in NK cells compared to that in other cell types. CD247, PLEKHF1, EOMES, S1PR5, and FGFBP2 were reduced expressed in AS patients as compare to control group verified by scRNA-seq data, CD247, EOMES, FGFBP2, IL2RB and S1PR5 were reduced expressed verified by RT-PCR, and PLEKHF1, S1PR5, and FGFBP2 was upregulated after TNF-α blocker therapy. CONCLUSION The study revealed the potential role of NK cells and identified IL2RB, CD247, PLEKHF1, EOMES, S1PR5, and FGFBP2 as key genes associated with NK cells in the pathogenesis of AS.

Abstract
The vascular network, uniquely sensitive to mechanical changes, translates biophysical forces into biochemical signals for vessel function. This process relies on the cell's architectural integrity, enabling uniform responses to physical stimuli. Recently, the nuclear envelope (NE) has emerged as a key regulator of vascular cell function. Studies implicate nucleoskeletal elements (e.g. nuclear lamina) and the linker of nucleoskeleton and cytoskeleton (LINC) complex in force transmission, emphasizing nucleo-cytoskeletal communication in mechanotransduction. The nuclear pore complex (NPC) and its component proteins (i.e. nucleoporins) also play roles in cardiovascular disease (CVD) progression. We herein summarize evidence on the roles of nuclear lamina proteins, LINC complex members, and nucleoporins in endothelial and vascular cell mechanotransduction. Numerous studies attribute NE components in cytoskeletal-related cellular behaviors to insinuate dysregulation of nucleocytoskeletal feedback and nucleocytoplasmic transport as a mechanism of endothelial and vascular dysfunction, and hence implications for aging and vascular pathophysiology.

Abstract
Obstructive sleep apnea (OSA) is characterized by intermittent hypoxia/hypercapnia (IHC), affects predominantly obese individuals, and increases atherosclerosis risk. Since we and others have implicated gut microbiota and metabolites in atherogenesis, we dissected their contributions to OSA-induced atherosclerosis. Atherosclerotic lesions were compared between conventionally-reared specific pathogen free (SPF) and germ-free (GF) Apoe-/- mice following a high fat high cholesterol diet (HFHC), with and without IHC conditions. The fecal microbiota and metabolome were profiled using 16S rRNA gene amplicon sequencing and untargeted tandem mass spectrometry (LC-MS/MS) respectively. Phenotypic data showed that HFHC significantly increased atherosclerosis as compared to regular chow (RC) in both aorta and pulmonary artery (PA) of SPF mice. IHC exacerbated lesions in addition to HFHC. Differential abundance analysis of gut microbiota identified an enrichment of Akkermansiaceae and a depletion of Muribaculaceae (formerly S24-7) family members in the HFHC-IHC group. LC-MS/MS showed a dysregulation of bile acid profiles with taurocholic acid, taurodeoxycholic acid, and 12-ketodeoxycholic acid enriched in the HFHC-IHC group, long-chain N-acyl amides, and phosphatidylcholines. Interestingly, GF Apoe-/- mice markedly reduced atherosclerotic formation relative to SPF Apoe-/- mice in the aorta under HFHC/IHC conditions. In contrast, microbial colonization did not show a significant impact on the atherosclerotic progression in PA. In summary, this research demonstrated that (1) IHC acts cooperatively with HFHC to induce atherosclerosis; (2) gut microbiota modulate atherogenesis, induced by HFHC/IHC, in the aorta not in PA; (3) different analytical methods suggest that a specific imbalance between Akkermansiaceae and Muribaculaceae bacterial families mediate OSA-induced atherosclerosis; and (4) derived bile acids, such as deoxycholic acid and lithocholic acid, regulate atherosclerosis in OSA. The knowledge obtained provides novel insights into the potential therapeutic approaches to prevent and treat OSA-induced atherosclerosis.

Abstract
Antagonism of the neonatal Fc receptor through an engineered antibody Fc fragment, such as efgartigimod, results in a decrease in immunoglobulin G levels. This approach is being evaluated as a therapeutic strategy for the treatment of IgG-mediated autoimmune diseases. Our goal was to evaluate the impact of mFc-ABDEG, a mouse-adapted antibody Fc fragment with a mode of action highly similar to efgartigimod, on vaccine-induced protective immune responses against viral infections. Therefore, mouse vaccination models for COVID-19 and influenza were employed, utilizing an mRNA COVID-19 vaccine (COMIRNATY) and an adjuvanted, inactivated quadrivalent influenza vaccine (Seqirus+AddaVax), respectively. In both models, vaccination induced robust humoral responses. As expected, animals treated with mFc-ABDEG had lower levels of virus-specific IgG, while virus-specific IgM responses remained unaffected. The COVID-19 vaccine induced a strong Th1-type T cell response irrespective of mFc-ABDEG treatment. Influenza vaccination resulted in a poor T cell induction, regardless of mFc-ABDEG treatment, due to the Th2-biased response that inactivated influenza vaccines typically induce. Importantly, mFc-ABDEG treatment had no effect on protective immunity against live viral challenges in both models. Vaccinated animals treated with mFc-ABDEG were equally protected as the non-treated vaccinated controls. These non-clinical data demonstrate that FcRn antagonism with mFc-ABDEG did not affect the generation of vaccine-induced protective humoral and cellular responses, or protection against viral challenges. These data substantiate the clinical observations that, although IgG titers were reduced, FcRn antagonism with efgartigimod did not impair the ability to generate new specific IgG responses, regardless of the timing of vaccination.

Cancer Biol Ther 2025; 26:2477365. [PMID: 40065703 PMCID: PMC11901378 DOI: 10.1080/15384047.2025.2477365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2024] [Revised: 02/25/2025] [Accepted: 03/05/2025] [Indexed: 03/14/2025] Open
Abstract
PURPOSE Abnormal expression of PINCH-1 has been observed in various types of human cancers. However, the clinical importance and mechanism underlying its role in head and neck squamous cell carcinoma (HNSCC) is yet to be fully elucidated. METHODS This study evaluated the expression of PINCH-1 in HNSCC samples through immunohistochemical staining and Western blotting. AMC-HN-8, Cal27, and SCC7 cell lines were utilized for cellular function experiments, both in vivo and in vitro. CCK8, colony-formation assay, flow cytometry, wound-healing assay, and transwell assay were employed to investigate the effects of alterations in target proteins on the growth and metastasis of cancer cells. Mito-Tracker Deep Red FM was used to track mitochondrial morphology. RESULTS PINCH-1 was found to be overexpressed in HNSCC and closely associated with lymph node metastasis and poor pathologic differentiation. Its upregulation promoted proliferation, inhibited apoptosis, and enhanced migration and invasion in HNSCC cells. It also promoted mitochondrial fission. We conducted a mechanism analysis, which showed that PINCH-1 knockdown inhibited mitochondrial fission by reducing the expression of DRP1. Furthermore, inhibition of mitochondrial fission could impede the proliferation and metastasis of HNSCC cells. Re-expression of DRP1 reversed the inhibitory effect of PINCH-1 knockdown on mitochondrial fission, cell proliferation, and metastasis in HNSCC cells. CONCLUSIONS PINCH-1 plays a critical oncogenic role in HNSCC by enhancing DRP1-mediated mitochondrial fission, which may serve as a novel therapeutic target for HNSCC.
