[PMID: 38628735 PMCID: PMC11019104 DOI: 10.1016/j.heliyon.2024.e28029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 02/28/2024] [Accepted: 03/11/2024] [Indexed: 04/19/2024] Open
Abstract
Despite extensive research reveal rheumatoid arthritis (RA) is related to atherosclerosis (AS), common pathogenesis between these two diseases still needs to be explored. In current study, we explored the common pathogenesis between rheumatoid arthritis (RA) and atherosclerosis (AS) by identifying 297 Differentially Expressed Genes (DEGs) associated with both diseases. Through KEGG and GO functional analysis, we highlighted the correlation of these DEGs with crucial biological processes such as the vesicle transport, immune system process, signaling receptor binding, chemokine signaling and many others. Employing Protein-Protein Interaction (PPI) network analysis, we elucidated the associations between DEGs, revealing three gene modules enriched in immune system process, vesicle, signaling receptor binding, Pertussis, and among others. Additionally, through CytoHubba analysis, we pinpointed 11 hub genes integral to intergrin-mediated signaling pathway, plasma membrane, phosphotyrosine binding, chemokine signaling pathway and so on. Further investigation via the TRRUST database identified two key Transcription Factors (TFs), SPI1 and RELA, closely linked with these hub genes, shedding light on their regulatory roles. Finally, leveraging the collective insights from hub genes and TFs, we proposed 10 potential drug candidates targeting the molecular mechanisms underlying RA and AS pathogenesis. Further investigation on xCell revealed that 14 types of cells were all different in both AS and RA. This study underscores the shared pathogenic mechanisms, pivotal genes, and potential therapeutic interventions bridging RA and AS, offering valuable insights for future research and clinical management strategies.

Abstract
Dental pulp cells play a crucial role in maintaining the balance of the pulp tissue. They actively respond to bacterial inflammation by producing proinflammatory cytokines, particularly interleukin-6 (IL-6). While many cell types release adenosine triphosphate (ATP) in response to various stimuli, the mechanisms and significance of ATP release in dental pulp cells under inflammatory conditions are not well understood. This study aimed to investigate ATP release and its relationship with IL-6 during the inflammatory response in immortalized human dental pulp stem cells (hDPSC-K4DT) following lipopolysaccharide (LPS) stimulation. We found that hDPSC-K4DT cells released ATP extracellularly when exposed to LPS concentrations above 10 μg/mL. ATP release was exclusively attenuated by N-ethylmaleimide, whereas other inhibitors, including clodronic acid (a vesicular nucleotide transporter inhibitor), probenecid (a selective pannexin-1 channel inhibitor), meclofenamic acid (a selective connexin 43 inhibitor), suramin (a nonspecific P2 receptor inhibitor), and KN-62 (a specific P2X7 antagonist), did not exhibit any effect. Additionally, LPS increased IL-6 mRNA expression, which was mitigated by the ATPase apyrase enzyme, N-ethylmaleimide, and suramin, but not by KN-62. Moreover, exogenous ATP induced IL-6 mRNA expression, whereas ATPase apyrase, N-ethylmaleimide, and suramin, but not KN-62, diminished ATP-induced IL-6 mRNA expression. Overall, our findings suggest that LPS-induced ATP release stimulates the IL-6 pathway through P2-purinoceptor, indicating that ATP may function as an anti-inflammatory signal, contributing to the maintenance of dental pulp homeostasis.

Abstract
Because of the devastating health effects of social determinants of health (SDoH), it is important for the primary care provider to assess and monitor these types of stressors. This can be done via surveys, geomapping, or various biomarkers. To date, however, each of these methods is fraught with obstacles. There are currently are no validated "best" SDoH screening tools for use in clinical practice. Nor is geomapping, a perfect solution. Although mapping can collect location specific factors, it does not account for the fact that patients may live in one area, work in another and travel frequently to a third.

Abstract
Epilepsy is defined as spontaneous recurrent seizures in the brain. There is increasing evidence that inflammatory mediators and immune cells are involved in epileptic seizures. As more research is done on inflammatory factors and immune cells in epilepsy, new targets for the treatment of epilepsy will be revealed. The Janus kinase-signal transducer and transcriptional activator (JAKSTAT) signaling pathway is strongly associated with many immune and inflammatory diseases, At present, more and more studies have found that the JAK-STAT pathway is involved in the development and development of epilepsy, indicating the JAK-STAT pathway's potential promise as a target in epilepsy treatment. In this review, we discuss the composition, activation, and regulation of the JAK-STAT pathway and the relationship between the JAK-STAT pathway and epilepsy. In addition, we summarize the common clinical inhibitors of JAK and STAT that we would expect to be used in epilepsy treatment in the future.

Network pharmacology and in vivo experiments reveal the pharmacological effects and molecular mechanisms of Simiao Powder in prevention and treatment for gout. BMC Complement Med Ther 2022; 22:152. [PMID: 35672755 PMCID: PMC9175488 DOI: 10.1186/s12906-022-03622-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 05/13/2022] [Indexed: 11/10/2022] Open
Abstract
Background Gout is a common disease with high incidence due to unhealthy diet and living habits. Simiao Powder, as a classic formula consisted of four common herbs, has been widely used in clinical practice since ancient times to prevent and treat gout. However, the pharmacological mechanism of Simiao Powder is still unclear. Methods Based on network pharmacology, Simiao Powder active compounds were identified in TCMSP, ETCM and BATMAN database, used to establish a network of interaction between potential targets of Simiao Powder and known therapeutic targets of gout. Subsequently, the key potential targets are being used for protein–protein interaction, GO enrichment analysis and KEGG pathway enrichment analysis through several authoritative open databases. Molecular docking through AutoDockTools software can verify interaction between molecules. Finally, to validate the predicted results, in vivo experiments based on hyperuricemic-gout mice model were designed and treated with Simiao powder and allopurinol. Serum levels of uric acid (UA), creatinine (Cr), blood urea nitrogen (BUN) and xanthine oxidase (XOD) were determined using a customized assay kit while the expression of PPAR-γ, PTGS1, IL-6 and Bcl2 mRNA were analyzed through qRT-PCR. Results Disease-target-compound network was visualized basing on the 20 bioactive compounds and the 19 potential targets using Cytoscape software. The results of PPI analysis, GO enrichment and KEGG pathway enrichment analysis indicate that the potential mechanism of Simiao Powder in treating gout may be achieved by regulating immune and inflammatory reactions, improving metabolism and endocrine. The results of molecular docking show that most of the targets and components have good binding activity. In vivo experiments revealed that Simiao powder can decreased serum UA and XOD levels in hyperuricemic-gout mice, and improved renal function. Furthermore, Simiao powder certainly regulates the expression of PPAR-γ, PTGS1, IL-6 and Bcl2 mRNA in ankle tissue in hyperuricemic-gout mice. Conclusion Collectively, this research predicted a multiple compounds, targets, and pathways model mechanism of Simiao Powder in the prevention and treatment of gout, providing new ideas and methods for in-depth research, via vivo experiments.

Abstract
The aims of this study were (1) to compare the levels and interactions of several plasma proteins in patients with myogenous temporomandibular disorders (TMDM) compared to healthy and pain-free controls, (2) to compare the levels and interactions in two TMDM subgroups, myalgia (MYA) and myofascial pain (MFP), and (3) to explore associations between the proteins and clinical data. Thirty-nine patients with TMDM (MFP, n = 25, MYA, n = 14), diagnosed according to the diagnostic criteria for TMD (DC/TMD), aged 38 years, and sex-matched pain-free controls completed an extended DC/TMD Axis II questionnaire and the plasma concentration of 87 biomarkers were analyzed. Nine proteins separated TMDM from controls (p = 0.0174) and 12 proteins separated MYA from MFP (p = 0.019). Pain duration, characteristic pain intensity, pain catastrophizing, perceived stress, and insomnia severity were significantly associated with protein markers (p < 0.001 to p < 0.022). In conclusion, several plasma proteins were upregulated in TMDM and either upregulated or downregulated in MYA compared to MFP. Some proteins in TMDM were associated with pain variables, sleep disturbance, and emotional function. These results show that systemic differences in protein expression exist in patients with TMDM and that altered levels of specific plasma proteins are associated with different clinical variables.

Abstract
Sleep is essential for optimal child development and health during the life course. However, sleep disturbances are common in early childhood and increase the risk of cognitive, metabolic and inflammatory disorders throughout life. Sleep and immunity are mutually linked, and cytokines secreted by immune cells could mediate this interaction. The sleep modulation of cytokines has been studied mostly in adults and adolescents; few studies have focused on school-aged children and none on preschoolers. We hypothesized that night sleep duration affects cytokine levels in preschoolers. In a sample of 687 children from the EDEN French birth cohort, we studied the associations between night sleep duration trajectories from age to 2–5 years old and serum concentrations of four cytokines (Tumor necrosis factor α [TNF-α], Interleukin 6 [IL-6], IL-10, Interferon γ [IFN)-γ] at age 5, adjusting for relevant covariates. As compared with the reference trajectory (≈11h30/night sleep, 37.4% of children), a shorter sleep duration trajectory (<10 h/night, 4.5% of children), and changing sleep duration trajectory (≥11h30/night then 10h30/night, 5.6% of children) were associated with higher serum levels of IL-6 and TNF-α, respectively at age 5. We found no associations between sleep duration trajectories and IL-10 or IFN-γ levels. This first longitudinal study among children aged 2–5 years old suggests an impact of sleep duration on immune activity in early childhood. Our study warrants replication studies in larger cohorts to further explore whether and how immune activity interacts with sleep trajectories to enhance susceptibility to adverse health conditions.

Abstract
An autoimmune disease is an inappropriate response to one's tissues due to a break in immune tolerance and exposure to self-antigens. It often leads to structural and functional damage to organs and systemic disorders. To date, there are no effective interventions to prevent the progression of autoimmune diseases. Hence, there is an urgent need for new treatment targets. TRPM7 is an enzyme-coupled, transient receptor ion channel of the subfamily M that plays a vital role in pathologic and physiologic conditions. While TRPM7 is constitutively activated under certain conditions, it can regulate cell migration, polarization, proliferation and cytokine secretion. However, a growing body of evidence highlights the critical role of TRPM7 in autoimmune diseases, including rheumatoid arthritis, multiple sclerosis and diabetes. Herein, we present (a) a review of the channel kinase properties of TRPM7 and its pharmacological properties, (b) discuss the role of TRPM7 in immune cells (neutrophils, macrophages, lymphocytes and mast cells) and its upstream immunoreactive substances, and (c) highlight TRPM7 as a potential therapeutic target for autoimmune diseases.

Abstract
Viruses are an underappreciated cause of heart failure. Indeed, several types of viral infections carry cardiovascular risks. Understanding shared and unique mechanisms by which each virus compromises heart function is critical to inform on therapeutic interventions. This review describes how the key viruses known to lead to cardiac dysfunction operate. Both direct host-damaging mechanisms and indirect actions on the immune systems are discussed. As viral myocarditis is a key pathologic driver of heart failure in infected individuals, this review also highlights the role of cytokine storms and inflammation in virus-induced cardiomyopathy.

Abstract
There is an urgent need for therapeutic interventions for desensitization and antibody-mediated rejection (AMR) in sensitized patients with preformed or de novo donor-specific HLA antibodies (DSA). The risk of AMR and allograft loss in sensitized patients is increased due to preformed DSA detected at time of transplant or the reactivation of HLA memory after transplantation, causing acute and chronic AMR. Alternatively, de novo DSA that develops post-transplant due to inadequate immunosuppression and again may lead to acute and chronic AMR or even allograft loss. Circulating antibody, the final product of the humoral immune response, has been the primary target of desensitization and AMR treatment. However, in many cases these protocols fail to achieve efficient removal of all DSA and long-term outcomes of patients with persistent DSA are far worse when compared to non-sensitized patients. We believe that targeting multiple components of humoral immunity will lead to improved outcomes for such patients. In this review, we will briefly discuss conventional desensitization methods targeting antibody or B cell removal and then present a mechanistically designed desensitization regimen targeting plasma cells and the humoral response.

Abstract
OBJECTIVES We sought to determine whether cranberry juice consumption would ameliorate laboratory and clinical measurements of disease activity in people with rheumatoid arthritis receiving fish oil supplementation. METHODS A prospective study was performed with 62 people with rheumatoid arthritis. We analyzed C-reactive protein modification of the Disease Activity Score-28 (DAS28-CRP) and inflammatory markers. The first group was assigned to eat their typical diet, a second group was asked to consume 3 g of fish oil ω-3 fatty acids daily, and a third group received both 3 g of fish oil n-3 fatty acids and 500 mL of reduced-calorie cranberry juice daily. RESULTS Compared with baseline values, the group receiving both fish oil and cranberry juice showed reductions in erythrocyte sedimentation rate (P = 0.033), C-reactive protein (P = 0.002), DAS28-CRP (P = 0.001), adiponectin (P = 0.021), and interleukin-6 levels (P = 0.045), whereas the fish oil group showed decreased DAS28-CRP (P = 0.0261) and adiponectin (P = 0.0239). Differences across treatments showed that the group receiving both fish oil and cranberry experienced reductions (P < 0.05) in erythrocyte sedimentation rate and C-reactive protein compared to the control group and the group treated with fish oil alone, and a reduction in DAS28-CRP was verified when the fish oil and cranberry group was compared to the control group. CONCLUSIONS The ingestion of cranberry juice adds beneficial effects to fish oil supplementation, decreasing disease activity and inflammatory biomarkers in people with rheumatoid arthritis.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is complex autoimmune system disease and significant impact on the health of population in our world. Numerous studies confirmed that genetic factors play a crucial role in the pathogenesis of RA. In this current study, we aimed to investigate IL-6 polymorphisms and RA risk in Chinese Han population. METHODS 508 RA patients and 494 age- and gender- matched healthy controls were recruited, all subjects were genotyped with an Agena MassARRAY platform. Subsequently, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by unconditional logistic regression after adjusting for age and gender. RESULTS Our results suggested that IL-6 rs2243289 allele and genotype frequencies were associated with reduced RA risk under all genetic models (all p < 0.05). Stratification analysis revealed that IL-6 rs2243289 polymorphism was significant associated with decreased the risk of RA in the old groups (age > 54) (all p < 0.05). However, IL-6 rs2069837 and rs1800796 polymorphisms were associated with increased risk of RA among the young groups (age ≤ 54) (all p < 0.05). In addition, subgroup analysis by gender suggested that IL-6 rs2069837 and rs1800796 polymorphism were interacted with increased the risk of RA in males (all p < 0.05). Besides, IL-6 rs2243289 was associated with reduced RA risk in females. CONCLUSIONS In conclusion, our results demonstrated the correlation between IL and 6 polymorphisms and RA susceptibility and confirmed for the first time that the relationship was restricted to age and gender in Chinese Han population.

Abstract
The past 2 decades have seen a revolution in our approach to therapeutic immunosuppression. We have moved from relying on broadly active traditional medications, such as prednisolone or methotrexate, toward more specific agents that often target a single receptor, cytokine, or cell type, using monoclonal antibodies, fusion proteins, or targeted small molecules. This change has transformed the treatment of many conditions, including rheumatoid arthritis, cancers, asthma, and inflammatory bowel disease, but along with the benefits have come risks. Contrary to the hope that these more specific agents would have minimal and predictable infectious sequelae, infectious complications have emerged as a major stumbling block for many of these agents. Furthermore, the growing number and complexity of available biologic agents makes it difficult for clinicians to maintain current knowledge, and most review articles focus on a particular target disease or class of agent. In this article, we review the current state of knowledge about infectious complications of biologic and small molecule immunomodulatory agents, aiming to create a single resource relevant to a broad range of clinicians and researchers. For each of 19 classes of agent, we discuss the mechanism of action, the risk and types of infectious complications, and recommendations for prevention of infection.

Abstract
This study aimed to examine complementary and alternative medicine (CAM) use among patients with ankylosing spondylitis (AS) who had or who had not received treatment with biological agents; the study also aimed to determine the types of CAM methods used by these patients. This is a comparative and cross-sectional study. This research was conducted at a rheumatology outpatient clinic of a university hospital in Turkey. A total of 120 patients who had (n = 60) and had not (n = 60) received therapy with biological agents participated in this study. A patient identification form and a questionnaire prepared by the researchers were used to collate the study data. This study found that the most commonly used method among patients who did not receive biological therapy was thermal facilities, at a rate of 28.3%; and that the most commonly used method among patients who did receive biological therapy was the use of thermal facilities, at a rate of 25%. No significant difference was found between patients who had received and patients who had not received biological therapy in terms of age and disease duration. Information was provided by health professionals to the patients concerning frequently used CAM modalities.

Med Res Rev 2020; 40:606-632.

Abstract
Nowadays, melatonin, previously considered only as a pharmaceutical product for rhythm regulation and sleep aiding, has shown its potential as a co-adjuvant treatment in intestinal diseases, however, its mechanism is still not very clear. A firm connection between melatonin at a physiologically relevant concentration and the gut microbiota and inflammation has recently established. Herein, we summarize their crosstalk and focus on four novelties. First, how melatonin is synthesized and degraded in the gut and exerts potentially diverse phenotypic effects through its diverse metabolites. Second, how melatonin mediates the activation and proliferation of intestinal mucosal immune cells with paracrine and autocrine properties. By modulating T/B cells, mast cells, macrophages and dendritic cells, melatonin immunomodulatory involved in regulating T-cell differentiation, intervening T/B cell interaction and attenuating the production of pro-inflammatory factors, achieving its antioxidant action via specific receptors. Third, how melatonin exerts antimicrobial action and modulates microbial components, such as lipopolysaccharide, amyloid-β peptides via nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) or signal transducers and activators of transcription (STAT1) pathway to modulate intestinal immune function in immune-pineal axis. The last, how melatonin mediates the effect of intestinal bacterial activity signals on the body rhythm system through the NF-κB pathway and influences the mucosal epithelium oscillation via clock gene expression. These processes are achieved at mitochondrial and nuclear levels to control the host immune cell development. Considering unclear mechanisms and undiscovered actions of melatonin in gut-microbiome-immune axis, it's time to reveal them and provide new insight for the outlook of melatonin as a potential therapeutic target in the treatment and management of intestinal diseases.

Relationships Among and Predictive Values of Obesity, Inflammation Markers, and Disease Severity in Pediatric Patients with Obstructive Sleep Apnea Before and After Adenotonsillectomy. J Clin Med 2020; 9:jcm9020579.

Abstract
Both obstructive sleep apnea (OSA) and obesity are major health issues that contribute to increased systemic inflammation in children. To date, adenotonsillectomy (AT) is still the first-line treatment for childhood OSA. However, the relationships among and predictive values of obesity, inflammation, and OSA severity have not been comprehensively investigated. This prospective study investigated body mass index (BMI), serum inflammatory markers, and OSA severity before and after AT in 60 pediatric patients with OSA. At baseline, differences in levels of interleukin-6, interleukin-9, basic fibroblast growth factor, platelet-derived growth factor-BB, as well as regulated on activation, normal T cell expressed and secreted (RANTES) were significant among the various weight status and OSA severity subgroups. After 3 months postoperatively, the differences in these inflammatory markers diminished along with a decrease in OSA severity while obesity persisted. The rate of surgical cure (defined as postoperative obstructive apnea-hypopnea index < 2.0 and obstructive apnea index < 1.0) was 62%. Multivariate analysis revealed that age, BMI z-score, granulocyte-macrophage colony-stimulating factor, monocyte chemotactic protein-1, and RANTES independently predicted surgical cure. Despite the significant reductions in inflammatory markers and OSA severity after AT, an inter-dependent relationship between obesity and OSA persisted. In addition to age and BMI, several inflammatory markers helped to precisely predict surgical cure.

Abstract
Ultraviolet (UV) irradiation affects neuronal structures of the skin and accelerates skin aging. Cytokine cascades in keratinocytes after UV irradiation may result in a paracrine inhibitory effect on nerve cells. The purpose of the present study was to determine the direct effect of cytokines induced by UV radiation on nerve cells in terms of neuronal senescence. Our group performed a preliminary study to determine cytokines induced in UV-irradiated keratinocytes. Among 40 cytokines studied, granulocyte-macrophage colony-stimulating factor (GM-CSF) was increased 4-fold in inflammation antibody array. The GM-CSF was added to cultured human neuroblastoma cells. To evaluate the effect of cellular senescence, the authors performed real-time polymerase chain reaction (RT-PCR), western blot, immunocytochemical, and phase-contrast microscopic evaluations. Expression levels of matrix metallopeptidase-9 (MMP-9), nuclear factor kappa-light-chain-enhancer of activated B cells 1 (NF-κB1), inducible nitric oxide synthase (iNOS), and interleukin β1 (IL-β1) were assessed by RT-PCR. Expression levels of AAP and beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) related to formation of beta-amyloid were evaluated by western blot analysis. Expression levels of MMP-9, NF-κB1, iNOS, and IL-β1 after treatment with GM-CSF were significantly higher than those in the control group. Enhanced expression of AAP and BACE1 was also observed in the treatment group. Thus, GM-CSF might have a provocative effect on nerve cells in terms of neuronal senescence.

Abstract
Hedgehog (Hh) pathway hyperactivation has been observed in various tumors, including breast cancer, and Hh pathway inhibitors have demonstrated antitumor activity in breast cancer. The tumor microenvironment (TME) has been shown to play an important role in modulating cancer cell drug sensitivity, but the TME response to Hh pathway inhibitors is unclear. In the current study, we observed increased TME infiltration of macrophages in breast cancer tissue, and specifically, M2 polarized macrophages after neoadjuvant chemotherapy. Furthermore, we observed an enhanced tolerance to Hh pathway inhibitors in MDA-MB-231 cells after co-culturing with M2 macrophages. In addition, we demonstrated that Hh pathway inhibition significantly induced IL6 expression, and validated that the tolerance to Hh pathway inhibitors was IL6-dependent. This study demonstrates a role of macrophages in Hh pathway inhibition resistance and a role of macrophage-derived IL6 in this resistance of breast cancer cells to Hh inhibition. These data indicate that antagonizing IL6 together with Hh pathway inhibitors may be a novel therapeutic strategy for breast cancer.

Abstract
Small-molecule inhibitors are widely used to treat a variety of inflammatory diseases. In this study, we found a novel anti-inflammatory compound, 1-[(2R,4S)-2-methyl-4-(phenylamino)-1,2,3,4-tetrahydroquinolin-1-yl]prop-2-en-1-one (MPQP). It showed strong anti-inflammatory effects in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. These effects were exerted through the inhibition of the production of NO and pro-inflammatory cytokines, such as interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α). Furthermore, MPQP decreased the expression levels of inducible NO synthase (iNOS) and cyclooxygenase 2 (COX-2). Additionally, it mediated the inhibition of the phosphorylation of p38, c-Jun N-terminal kinase (JNK), the inhibitor of κBα (IκBα), and their upstream kinases, IκB kinase (IKK) α/β, mitogen-activated protein kinase kinase (MKK) 3/6, and MKK4. Furthermore, the expression of IL-1 receptor-associated kinase 1 (IRAK1) that regulates NF-κB, p38, and the JNK signaling pathways, was also increased by MPQP. These results indicate that MPQP regulates the IRAK1-mediated inflammatory signaling pathways by targeting IRAK1 or its upstream factors.

Abstract
Background To examine the expression of ADAM-17 in rheumatoid arthritis (RA) biological fluids and the role it plays in monocyte adhesion to RA fibroblast-like synoviocytes (FLSs). Methods ADAM-17 expression was measured by enzyme-linked immunosorbent assays (ELISAs) in serum from normal (NL) subjects, osteoarthritis (OA) patients, and RA patients. We also analyzed the correlation between ADAM-17 and disease activity score 28 (DAS28) in RA. To determine expression of ADAM-17 in RA synovial tissues (STs) and RA FLS, we performed immunofluorescence analyses. To determine the role of ADAM-17 in RA, we transfected RA FLSs with small interfering RNA (siRNA) against ADAM-17. THP-1 adhesion to ADAM-17 siRNA-transfected RA FLSs was measured. Finally, adhesion molecules on ADAM-17 siRNA-transfected RA FLSs were measured using cell surface ELISAs. Results ADAM-17 in RA serum was significantly higher than that in NL and OA serum and correlated with DAS28. ADAM-17 in RA synovial fluids was higher than that in OA synovial fluids. ADAM-17 was expressed on RA cells lining STs and RA FLSs. THP-1 adhesion to ADAM-17 siRNA-transfected RA FLSs was decreased compared with that to control siRNA-transfected RA FLSs. ICAM-1 on TNF-α-stimulated ADAM-17 siRNA-transfected RA FLSs was significantly decreased compared with that on control siRNA-transfected RA FLSs. Conclusions These data indicate that ADAM-17 is expressed on RA STs and plays a role in RA inflammation by regulating monocyte adhesion to RA FLSs. ADAM-17 might be an important inflammatory mediator in inflammatory diseases such as RA.

Abstract
Epilepsy, a neurological disease characterized by recurrent seizures, is often associated with a history of previous lesions in the nervous system. Impaired regulation of the activation and resolution of inflammatory cells and molecules in the injured neuronal tissue is a critical factor to the development of epilepsy. However, it is still unclear as to how that unbalanced regulation of inflammation contributes to epilepsy. Therefore, one of the goals in epilepsy research is to identify and elucidate the interconnected inflammatory pathways in systemic and neurological disorders that may further develop epilepsy progression. In this paper, inflammatory molecules, in neurological and systemic disorders (rheumatoid arthritis, Crohn’s, Type I Diabetes, etc.) that could contribute to epilepsy development, are reviewed. Understanding the neurobiology of inflammation in epileptogenesis will contribute to the development of new biomarkers for better screening of patients at risk for epilepsy and new therapeutic targets for both prophylaxis and treatment of epilepsy.

Abstract
Background Previously, we reported that ChondorT showed significant anti-arthritis and anti-inflammatory effects. ChondroT, a new herbal medication, consists of the water extracts of Osterici Radix, Lonicerae Folium, Angelicae Gigantis Radix, Clematidis Radix, and Phellodendri Cortex (6:4:4:4:3). The objective of this study was to investigate the effects of ChondroT in collagenase-induced osteoarthritis rat model. Methods Osteoarthritis was induced by the injection of collagenase into the right knee joint cavity of rats. The samples were divided into seven groups [intact (n = 6), control (n = 6), indomethacin (n = 6), Joins tab (n = 6), ChondroT50 (n = 6), ChondroT100 (n = 6), and ChondroT200 (n = 6)]. The control group was administered normal saline, indomethacin group was administered indomethacin (2 mg/kg), and Joins tab group was administered Joins Tab (20 mg/kg). The ChondroT50, ChondroT100, and ChondroT200 groups were administered 50, 100, and 200 mg/kg of ChondroT, respectively. All oral administrations were initiated 7 days after the induction of arthritis and were continued for a total of 12 days. At the end of the experiment, serum aminotransferase, albumin, blood urea nitrogen, creatinine, leukocyte, and inflammatory cytokines [tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6] were analyzed. Hematoxylin and eosin (H&E) and safranin O-fast green staining of the articular structures of the knee joint were performed. Results TNF-α and IL-1β decreased in the ChondroT100 and ChondroT200 groups compared with those in the control group. IL-6 and aspartate aminotransferase decreased in the ChondroT50, ChondroT100, and ChondroT200 groups compared with that in the control group. Albumin, WBC and lymphocytes decreased in the ChondroT100 and ChondroT200 groups compared with those in the control group. In H&E stain, synoviocytes, cartilage lacunae, and chondrocytes were well preserved in the ChondroT100 and ChondroT200 groups, and safranin O-fast staining showed a clear reaction of proteoglycans in the ChondroT100 and ChondroT200 groups. Conclusions Based on these results, it can be proposed that ChondroT has anti-osteoarthritic effects on collagenase-induced rat model.

Abstract
Complex diseases have heterogeneous underlying molecular mechanisms. In order to improve the diagnosis and treatment of disease, it is vital to stratify patients into homogeneous subgroups that share a similar disease etiology. In this study, we performed gene-level subtyping analysis on two independent Rheumatoid Arthritis gene expression cohorts from different ethnic groups to discover the possible disease mechanisms associated with each subtype. Also, a novel pathway-level analysis is proposed to increase the subtyping robustness and facilitate biological interpretation. This approach could stratify RA patients into two robust and homogeneous groups with differing activation of central signal transduction pathways and pro-inflammatory cytokines in the pathogenesis of RA. Such a methodology can help understand disease mechanisms at play in different patient sub-populations and also potentially explain why some patients don't respond to anti-TNF treatment.

Abstract
Background Mesenchymal stem cells (MSCs) have a therapeutic potential for the treatment of osteoarthritic (OA) joint pathology and pain. The aims of this study were to determine the influence of a passage number on the effects of MSCs on pain behaviour and cartilage and bone features in a rodent model of OA. Methods Rats underwent either medial meniscal transection (MNX) or sham surgery under anaesthesia. Rats received intra-articular injection of either 1.5 × 106 late passage MSCs labelled with 10 μg/ml SiMAG, 1.5 × 106 late passage mesenchymal stem cells, the steroid Kenalog (200 μg/20 μL), 1.5 × 106 early passage MSCs, or serum-free media (SFM). Sham-operated rats received intra-articular injection of SFM. Pain behaviour was quantified until day 42 postmodel induction. Magnetic resonance imaging (MRI) was used to localise the labelled cells within the knee joint. Results Late passage MSCs and Kenalog attenuated established pain behaviour in MNX rats, but did not alter MNX-induced joint pathology at the end of the study period. Early passage MSCs exacerbated MNX-induced pain behaviour for up to one week postinjection and did not alter joint pathology. Conclusion Our data demonstrate for the first time the role of a passage number in influencing the therapeutic effects of MSCs in a model of OA pain.

Abstract
The development of inhibitory autoantibodies to the infused clotting factor VIII (FVIII) is a major complication for severe hemophilia A management. Novel therapy options for hemophilia have significantly progressed in the last decade, and a gene therapy cure for hemophilia is becoming a reality. However, mechanistic studies of FVIII autoantibodies (FVIII inhibitors) have lagged behind and remain a challenge for both protein replacement and gene therapy. FVIII inhibitor formation is assumed to be a classical T cell-dependent immune response in which cytokines/chemokines play an important role. The study of cytokine profile changes during FVIII inhibitor development may be helpful to understand the mechanism of inhibitor development and to explore potential novel approaches that will minimize the risk. After FVIII-/- mice were treated with intravenous administration of an adeno-associated virus 8 vector encoding human FVIII, FVIII expression peaked at week 2 (W2), and FVIII inhibitor was thoroughly developed at week 8 (W8). W8 plasma that showed positive FVIII inhibitor, and W2 samples with negative FVIII inhibitor (anti-FVIII[+]), were subjected to multiplex cytokines measurement. W8 and W2 samples were both negative for FVIII inhibitor (anti-FVIII[-]) as the control. In comparison to mice in the anti-FVIII(-) group, mice in the anti-FVIII(+) group exhibited significantly elevated pro-inflammatory cytokines of interleukin (IL)-1, IL-6, IL-12p40, monocyte chemoattractant protein-1, macrophage inflammatory protein (MIP)-1, MIP-2, and tumor necrosis factor alpha (TNF-α), especially at higher titers. The anti-inflammatory cytokine of transforming growth factor beta (TGF-β) was decreased at W2 in both groups. Multivariate analysis of the risk factors for FVIII inhibitor development showed peak FVIII activity at W2. IL-6 and TNF-α at W8 were positively correlated with inhibitor formation, and negatively correlated with the age starting gene therapy. Collectively, the elevated monocyte derived pro-inflammatory cytokines/chemokines, together with the decreased anti-inflammatory cytokine of TGF-β at an early time point, may contribute to the persistent inflammatory environment in favor of an immune response toward FVIII inhibitor development.

Abstract
OBJECTIVES We aimed to evaluate the association between the change in serum IL-6 during the clinical course of tocilizumab (TCZ) therapy and rheumatoid arthritis (RA) disease activity or occurrence of adverse events. METHODS General laboratory data including serum IL-6 levels and physical findings were obtained every 4 weeks, and, in addition, at the time when any adverse events occurred. RESULTS The proportion achieving Clinical Disease Activity Index (CDAI) remission at 52 weeks was significantly lower in 20 patients with serum IL-6 ≥ 30 pg/ml at 12 weeks than 24 patients with serum IL-6 < 30 pg/ml. In 17 patients with serum IL-6 ≥ 30 pg/ml at 24 weeks, the proportion achieving CDAI remission was also significantly lower than 27 patients with serum IL-6 < 30 pg/ml then. In these 17 patients, Disease Activity Score (DAS) 28-ESR and CDAI at 52 weeks were significantly higher than those with serum IL-6 < 30 pg/ml. Age- and sex-adjusted logistic regression analysis showed logIL-6 at 12 weeks to be a predictive factor for DAS28-ESR remission at 52 weeks. CONCLUSION Serum IL-6 levels from 12 to 24 weeks after TCZ initiation better reflect the efficacy of TCZ at 52 weeks.

Abstract
Systemic sclerosis (SSc) is a connective tissue disease of unknown etiology, manifesting in patients as tissue fibrosis, endothelial dysfunction, and inflammation. The disease is characterized by autoantibodies, a hallmark of autoimmunity. Various cytokines and growth factors are elevated in the systemic circulation and fibrotic lesions of patients with SSc. In particular, several studies over the past 2 decades have shown that interleukin-6 (IL-6) appears to be involved in the pathogenesis of SSc. Based on the association between aberrant IL-6 production and tissue fibrosis in patients with SSc, the anti-IL-6 receptor antibody, tocilizumab, is being investigated in clinical trials. This article reviews the biological features of IL-6 and the IL-6 receptor; the role of IL-6 in the pathogenesis of SSc; and the potential for IL-6 inhibition to be used in the treatment of patients with SSc.

Abstract
Changes in maternal innate immunity during healthy human pregnancy are not well understood. Whether basal immune status in vivo is largely unaffected by pregnancy, is constitutively biased towards an inflammatory phenotype (transiently enhancing host defense) or exhibits anti-inflammatory bias (reducing potential responsiveness to the fetus) is unclear. Here, in a longitudinal study of healthy women who gave birth to healthy infants following uncomplicated pregnancies within the Canadian Healthy Infant Longitudinal Development (CHILD) cohort, we test the hypothesis that a progressively altered bias in resting innate immune status develops. Women were examined during pregnancy and again, one and/or three years postpartum. Most pro-inflammatory cytokine expression, including CCL2, CXCL10, IL-18 and TNFα, was reduced in vivo during pregnancy (20-57%, p<0.0001). Anti-inflammatory biomarkers (sTNF-RI, sTNF-RII, and IL-1Ra) were elevated by ~50-100% (p<0.0001). Systemic IL-10 levels were unaltered during vs. post-pregnancy. Kinetic studies demonstrate that while decreased pro-inflammatory biomarker expression (CCL2, CXCL10, IL-18, and TNFα) was constant, anti-inflammatory expression increased progressively with increasing gestational age (p<0.0001). We conclude that healthy resting maternal immune status is characterized by an increasingly pronounced bias towards a systemic anti-inflammatory innate phenotype during the last two trimesters of pregnancy. This is resolved by one year postpartum in the absence of repeat pregnancy. The findings provide enhanced understanding of immunological changes that occur in vivo during healthy human pregnancy.

Abstract
Rheumatoid arthritis (RA) is one of the most common autoimmune diseases, with a 0.5% worldwide prevalence. The cause of RA remains unknown, however both genetic and environmental factors may contribute to its development. Among these is the Epstein-Barr virus (EBV). Here, we discuss several aspects of the close relationship between EBV and RA. Patients with RA have impaired control of EBV infection. Indeed, they have high titres of antibodies against EBV antigens. Their peripheral blood T lymphocytes are less efficient at controlling the outgrowth of EBV-infected B cells. RA patients have more EBV-infected B cells than normal controls, leading to a 10-fold systemic EBV overload. Post-transplant lymphoproliferative disorder (PTLPD) is a polyclonal EBV-positive B lymphocyte proliferation, which can evolve into an EBV-positive B cell lymphoma. RA patients also have an increased risk of developing EBV-associated lymphoproliferative disorder (LPD). Hence the need to monitor EBV load when treating RA patients with immunosuppressors. EBV, a widespread virus, highly recognized by antibodies but never eliminated, is an ideal candidate to trigger chronic immune complex disease. Anti-EBV antibody responses should be considered as one of the chronic autoantibody responses linked to the development of RA, in the same way as anti-citrullinated protein antibodies.

Abstract
Cytokine-like protein 1 (CYTL1) is a small widely expressed secreted protein lacking significant primary sequence homology to any other known protein. CYTL1 expression appears to be highest in the hematopoietic system and in chondrocytes; however, maintenance of cartilage in mouse models of arthritis is its only reported function in vivo. Despite lacking sequence homology to chemokines, CYTL1 is predicted by computational methods to fold like a chemokine, and has been reported to function as a chemotactic agonist at the chemokine receptor CCR2 in mouse monocyte/macrophages. Nevertheless, since chemokines are defined by structure and chemokine receptors are able to bind many non-chemokine ligands, direct determination of the CYTL1 tertiary structure will ultimately be required to know whether it actually folds as a chemokine and therefore is a chemokine. Towards this goal, we have developed a method for producing functional recombinant human CYTL1 in bacteria, and we provide new evidence about the biophysical and biochemical properties of recombinant CYTL1. Circular dichroism analysis showed that, like chemokines, CYTL1has a higher content of beta-sheet than alpha-helix secondary structure. Furthermore, recombinant CYTL1 promoted calcium flux in chondrocytes. Nevertheless, unlike chemokines, CYTL1 had limited affinity to proteoglycans. Together, these properties further support cytokine-like properties for CYTL1 with some overlap with the chemokines.

Abstract
FlexPro MD® (FP-MD), a novel multi-ingredient dietary supplement formulation, has been demonstrated to relieve knee joint pain in humans. However, the mechanisms of action responsible for the activity of FP-MD have not been elucidated. In this study, we show the anti-inflammatory effects of FP-MD in RAW264.7 macrophage cells and mice challenged with lipopolysaccharide (LPS). FP-MD significantly inhibited the mRNA levels of pro-inflammatory cytokines, including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1β. In contrast, it elevated the mRNA levels of anti-inflammatory cytokine IL-10 in LPS-stimulated RAW264.7 cells. FP-MD markedly reduced LPS-induced phosphorylation levels of nuclear factor-κB (NF-κB) p65 and inhibitor of κB-α (IκB-α). Importantly, the anti-inflammatory effects of FP-MD were demonstrated in mice with LPS-induced inflammatory arthritis in which FP-MD significantly reduced the expression levels of pro-inflammatory cytokines and inflammatory markers. Thus, this study suggests that FP-MD has anti-inflammatory effects by inhibiting NF-κB that may offer a molecular basis for its pain relief property.

Abstract
Marine microalgal exopolysaccharides (EPSs) have drawn great attention due to their biotechnological potentials such as anti-viral, anti-oxidant, anti-lipidemic, anti-proliferative, and immunomodulatory activities, etc. In the present study, the EPS derived from microalgae Thraustochytriidae sp.-derived mutant GA was investigated for its anti-proliferation and immunomodulation. Anti-cancer efficacy of the microalgal EPS was examined for the alterations in cell proliferation and cell cycle-related gene expression that occur in three types of human cancer cell lines, BG-1 ovarian, MCF-7 breast, and SW-620 colon cancer cell lines, by its treatment. Alterations in immunoreactivity by the microalgal EPS were examined by measuring its influence on the growth of T and B lymphocytes and cytokine production of T cells. In cell viability assay, the microalgal EPS inhibited cancer cell growth at the lowest concentration of 10-11 dilution and in a dose-responsive manner within the range of dilution of 10-11~10-3. In addition, the protein expression of cell cycle progression genes such as cyclin D1 and E in these cancer cell lines was significantly reduced by the microalgal EPS in a dose- and a time-dependant manner. In cell proliferation assay using T and B cells, the microalgal EPS induced B cell proliferation even at the lowest dilution of 10-11, but not T cells. In cytokine assay, the microalgal EPS decreased the formation of IL-6 and INF-γ at 10-3 dilution compared to the control and had no significant effects on TNF-α. Collectively, these findings suggest that the EPS derived from microalgae Thraustochytriidae sp. GA has an anti-proliferative activity against cancer cells and an immunomodulatory effect by having an influence on B cell proliferation and cytokine secretion of T cells.

Long term treatment with abatacept or tocilizumab does not increase Epstein-Barr virus load in patients with rheumatoid arthritis - A three years retrospective study. PLoS One 2017; 12:e0171623. [PMID: 28199343 PMCID: PMC5310777 DOI: 10.1371/journal.pone.0171623] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2016] [Accepted: 01/23/2017] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Epstein-Barr Virus (EBV) is a widely disseminated lymphotropic herpes virus implicated in benign and malignant disorders. In transplant patients, immunosuppressive drugs (cyclosporine) diminish control of EBV replication, potentially leading to lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) patients have impaired control of EBV infection and have EBV load ten times higher than controls. As post transplant patients, patients with RA have increased risk of developing lymphomas. Immunosuppressive drugs used to treat RA (conventional disease modifying drugs cDMARDs or biologics bDMARDs) could enhance the risk of developing LPD in RA patients. We have previously shown that long term treatment with Methotrexate and/or TNF alpha antagonists does not increase EBV load in RA. Our objective was to monitor the Epstein-Barr Virus load in RA patients treated with Abatacept (CTLA4 Ig), a T cell coactivation inhibitor, and Tocilizumab, an anti IL6 receptor antibody. METHODS EBV load in the peripheral blood mononuclear cells (PBMCs) of 55 patients under Abatacept (in 34% associated with Methotrexate) and 35 patients under Tocilizumab (in 37% associated with Methotrexate) was monitored for durations ranging from 6 months to 3 years by real time PCR. The influences of treatment duration and disease activity score 28 (DAS28) index on EBV load were analyzed. RESULTS Abatacept did not significantly modify EBV load over time. Tocilizumab significantly diminished EBV load over time. No patient (of 90) developed EBV associated lymphoma. CONCLUSION Long term treatment with Abatacept or Tocilizumab does not increase EBV load in the PBMNCs of patients with RA.

Abstract
Systemic inflammation is involved in vascular calcification and cardiovascular disease which is the leading cause of mortality in rheumatoid arthritis (RA). A high level of serum interleukin (IL)-6 plays a key role in local and systemic inflammation in RA. However, the underlying mechanisms remain unclear. We established a human umbilical artery smooth muscle cell (HUASMC) culturing method to investigate the possible role of IL-6 on vascular calcification. HUASMCs were obtained from umbilical arteries of healthy neonates. To detect calcification effects, HUASMCs were treated with (experimental group) or without (control group) recombinant human (rh) IL-6. The calcium deposition stain and calcium concentrations were measured, as well as the mRNA and protein levels of the regulating factor of osteogenic differentiation-bone morphogenetic protein (BMP) 2 and those calcifying related molecules including bone-specific alkaline phosphatase (BAP), osteoprotegerin (OPG), and osteopontin (OPN). Our study showed that rhIL-6 induced calcification of HUASMCs in a time- and dose-dependent manner, and upregulated expressions of BMP2, BAP, OPG, and OPN of HUASMCs. We then used the anti-BMP2 siRNA to knockdown the expression of endogenous BMP2 to confirm its role. HUASMCs were transfected with negative siRNA (control group) or the valid anti-BMP2 siRNA (experimental group) before they were treated with rhIL-6. Cells transfected with negative siRNA without IL-6 stimulating served as the blank group. The results showed that anti-BMP2 siRNA markedly decreased expressions of BMP2, BAP, OPG, and OPN, and also partly reduced the calcification of HUASMCs induced by rhIL-6. Collectively, according to our study, rhIL-6 could induce the extracellular calcification and osteogenic differentiation of human artery smooth muscle cells through upregulating endogenous BMP2 in vitro. This may be one of the underlying mechanisms of the overwhelming vascular calcification in RA.

Abstract
To investigate the effects of inflammatory factor interleukin (IL)‑6 on the expression of endothelial lipase (EL) and its potential signaling pathways in atherosclerosis, a primary culture of human umbilical vein endothelial cells (HUVECs) was established and treated as follows: i) Control group without any treatment; ii) recombinant human (rh)IL‑6 treatment (10 ng/ml) for 0, 4, 8, 12 and 24 h; iii) p38 mitogen‑activated protein kinases (MAPKs) inhibitor (SB203580, 10 µmol/l) pretreatment for 1 h prior to rhIL‑6 (10 ng/ml) treatment; iv) nuclear factor (NF)‑κB activation inhibitor (pyrrolidine dithiocarbamate, 10 mmol/l) pretreatment for 1 h prior to rhIL‑6 (10 ng/ml) treatment. EL levels were detected by immunocytochemical staining and western blot analysis. Proliferation of HUVECs was detected by immunostaining of proliferating cell nuclear antigen (PCNA) and an MTT assay. p38 MAPK and NF‑κB p65 levels were detected by western blotting. The results showed that rhIL‑6 treatment increased EL expression and proliferation of HUVECs. NF‑κB p65 and MAPK p38 protein levels also increased in a time‑dependent manner in HUVECs after rhIL‑6 treatment. NF‑κB inhibitor and MAPK p38 inhibitor prevented the effects of rhIL‑6 on EL expression. In conclusion, inflammatory factor IL‑6 may participate in the pathogenesis of atherosclerosis by increasing EL expression and the proliferation of endothelial cells via the p38 MAPK and NF-κB signaling pathways.

Abstract
Background Takayasu arteritis is a chronic non-specific inflammatory disease and mean platelet volume can either be decreased or increased during inflammation. However, there are no published data to confirm an association between mean platelet volume and Takayasu arteritis. Our aim was to evaluate the role of mean platelet volume in patients with Takayasu arteritis. Methods A total of 119 consecutive patients with Takayasu arteritis and 217 healthy individuals were included in this study. Forty-five Takayasu arteritis patients with active disease were followed with prednisone therapy. Results Mean platelet volume of patients was low compared with control groups (10.1 ± 1.47 fL vs. 11.2 ± 0.91 fL; P < 0.001). Mean platelet volume was lower in active Takayasu arteritis than in inactive Takayasu arteritis patients (9.3 ± 1.39 fL vs. 10.6 ± 1.28 fL; P< 0.001). Mean platelet volume values were significantly increased after prednisone treatment (9.3 ± 1.45 fL vs. 10.5 ± 1.29 fL; P < 0.001). Mean platelet volume negatively correlated with C-reactive protein, erythrocyte sedimentation rate, neutrophil count and platelet count (r = − 0.219, P = 0.018; r = − 0.296, P < 0.001; r = − 0.273, P = 0.003; r =−0.486, P< 0.001), and positively correlated with platelet distribution width (r=0.304, P ≤ 0.001) in patients with Takayasu arteritis. An inverse correlation between mean platelet volume and erythrocyte sedimentation rate was observed in active Takayasu arteritis patients (r = −0.406, P = 0.010). In multiple linear regression analysis, mean platelet volume was independently correlated with erythrocyte sedimentation rate in patients with Takayasu arteritis. Conclusions Our results suggest that mean platelet volume may identify active disease in patients with Takayasu arteritis, and the values of mean platelet volume may help to establish remission of active disease after treatment in Takayasu arteritis patients.

Abstract
This broad review elaborates on the most up-to-date knowledge on biochemical and psychobiological aspects of parental loss and other childhood adversities during divorce involving minor children. So far, divorce involving minor children was unfortunately considered by authorities only as a purely juridical problem, and this approach has often allowed a completely different approach according to the Courts. Now, scientific research, also making use of animal models, is demonstrating the biological basis of the problem and the indisputable consequences on the well-being and health of children. The innovative conclusion of this review is that this argument (because of its frequency and gravity) is primarily a question of public health and that it is necessary to further harmonize practices in this area.

Krüppel-Like Factor 4 Is a Regulator of Proinflammatory Signaling in Fibroblast-Like Synoviocytes through Increased IL-6 Expression. Mediators Inflamm 2016; 2016:1062586.

Abstract
Human fibroblast-like synoviocytes play a vital role in joint synovial inflammation in rheumatoid arthritis (RA). Proinflammatory cytokines induce fibroblast-like synoviocyte activation and dysfunction. The inflammatory mediator Krüppel-like factor 4 is upregulated during inflammation and plays an important role in endothelial and macrophage activation during inflammation. However, the role of Krüppel-like factor 4 in fibroblast-like synoviocyte activation and RA inflammation remains to be defined. In this study, we identify the notion that Krüppel-like factor 4 is higher expressed in synovial tissues and fibroblast-like synoviocytes from RA patients than those from osteoarthritis patients. In vitro, the expression of Krüppel-like factor 4 in RA fibroblast-like synoviocytes is induced by proinflammatory cytokine tumor necrosis factor-α. Overexpression of Krüppel-like factor 4 in RA fibroblast-like synoviocytes robustly induced interleukin-6 production in the presence or absence of tumor necrosis factor-α. Conversely, knockdown of Krüppel-like factor 4 markedly attenuated interleukin-6 production in the presence or absence of tumor necrosis factor-α. Krüppel-like factor 4 not only can bind to and activate the interleukin-6 promoter, but also may interact directly with nuclear factor-kappa B. These results suggest that Krüppel-like factor 4 may act as a transcription factor mediating the activation of fibroblast-like synoviocytes in RA by inducing interleukin-6 expression in response to tumor necrosis factor-α.

Abstract
Since the discovery of leptin in 1994, our vision of adipose tissue as a static organ regulating mainly lipid storage and release has been completely overthrown, and adipose tissue is now seen as an active and integral organ in human physiology. In the past years, extensive research has tremendously given us more insights in the mechanisms and pathways involved not only in normal but also in 'sick' adipose tissue, for example, in obesity and lipodystrophy. With growing evidence of a link between obesity and several types of cancer, research focusing on the interaction between adipose tissue and cancer has begun to unravel the interesting but complex multi-lateral communication between the different players. With breast cancer as one of the first cancer types where a positive correlation between obesity and breast cancer incidence and prognosis in post-menopausal women was found, we have focused this review on the paracrine and endocrine role of adipose tissue in breast cancer initiation and progression. As important inter-species differences in adipose tissue occur, we mainly selected human adipose tissue- and breast cancer-based studies with a short reflection on therapeutic possibilities. This review is part of the special issue on "Adiposopathy in Cancer and (Cardio)Metabolic Diseases".

Abstract
INTRODUCTION Over 100 susceptibility loci have now been identified for rheumatoid arthritis (RA), several of which are already the targets of approved RA therapies providing proof of concept for the use of genetics in novel drug development for RA. Determining how these loci contribute to disease will be key to elucidating the mechanisms driving disease development, which has the potential for major impact on therapeutic development. AREAS COVERED Here the authors review the use of genetics in drug discovery, including the use of 'omics' data to prioritise potential drug targets at susceptibility loci using RA as an exemplar. They discuss the current state of RA genetics its impact on stratified medicine, and how the findings from RA genetics studies can be used to inform drug discovery. EXPERT OPINION It is anticipated that functional characterisation of disease variants will provide biological validation of a gene as a drug target, providing safer targets, with an increased likelihood of efficacy. In the future, techniques such as genome editing may represent a plausible option for RA therapy. Technologies such as genome-wide chromatin conformation capture Hi-C and CRISPR will be crucial to inform our understanding of how diseases develop and in developing new treatments.

Abstract
Coptis chinensis has been used for the treatment of inflammatory diseases in China and other Asian countries for centuries. However, the chemical constituents and mechanism underlying the anti-inflammatory activity of this medicinal plant are poorly understood. Here, coptisine, the main constituent of C. chinensis, was shown to potently inhibit the production of nitric oxide (NO) by suppressing the protein and mRNA expressions of inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Coptisine also inhibited the production of the pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-6 (IL-6) by suppressing expression of cytokine mRNA. Coptisine suppressed the degradation of inhibitor of nuclear factor κBα (IκBα) and phosphorylation of extracellular signal-regulated kinase (ERK), c-Jun NH2-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK), and phosphoinositide 3-kinase/Akt (PI3K/Akt). Coptisine had no effect on the expression of toll-like receptor 4 (TLR-4) and myeloid differentiation factor 88 (MyD88) as well as LPS binding to TLR-4. Coptisine also inhibited carrageenan-elicited rat paw edema and reduced the release of TNF-α and NO in rat inflamed tissue. These results suggest that coptisine inhibits LPS-stimulated inflammation by blocking nuclear factor-kappa B, MAPK, and PI3K/Akt activation in macrophages, and can be used as an agent for the prevention and treatment of inflammatory diseases.

Abstract
BACKGROUND AND OBJECTIVE The laser acupuncture has many potential therapeutic effects. Currently, they are not evaluated for their therapeutic effects on rheumatoid arthritis (RA) patients. The aim of this study was to investigate the effects of laser acupuncture on the oxidative and antioxidative markers, as well as the inflammatory markers and disease activity of RA patients. DESIGN/MATERIALS AND METHODS The study was conducted on 30 RA patients and 20 healthy subjects. The patients were subjected to laser acupuncture (904 nm, 100 mW power output, 1 minute irradiation time, beam area of 1 cm(2) , total energy per point 6 J, energy density 6 J/ cm(2) , irradiance 0.1 W/cm(2) , frequency 10000 Hz, duty-cycle 100%) for 3 days/week for duration of 4 weeks. The acupuncture points of exposure were LI4, TE5, LI 11, DU 14, LIV3, SP6, GB34, and S36. The levels of oxidative and antioxidant markers were determined by spectrophotometric methods whereas the inflammatory markers were determined by ELISA methods. Lastly, using DAS28 scores the disease activity was assessed. RESULTS After laser acupuncture, the study group revealed significantly increased plasma superoxide dismutase (SOD), glutathione reductase (GR), catalase activities, blood glutathione (GSH), and plasma ATP concentrations, compared to those before treatment (P < 0.0005). Moreover, the results revealed significantly reduced plasma malondialdehyde (MDA), serum nitrate and nitrite, serum C-reactive protein (CRP), plasma interleukin-6 (IL-6) levels and significantly reduced glutathione peroxidase (GPx) activity and erythrocyte sedimentation rate (ESR) in laser exposed patients, compared to those before treatment (P < 0.0005). The RA patients subjected to laser acupuncture showed highly significant reduction in disease activity (P < 0.0005) based on DAS28 score. CONCLUSION Our study results confirmed the effectiveness of laser acupuncture in alleviating oxidative stress and inflammation, improving antioxidant and energy metabolic status, while also suppressing the disease activity in RA patients. Laser acupuncture is a promising treatment modality to reduce the pain and suffering of RA patients because of its efficiency in inhibiting most of the main factors involved in the pathogenesis of this disease.

Abstract
Purpose. Interleukin 6 (IL-6) plays a crucial role in both adaptive and innate immunity. The rs1800795 gene polymorphism of IL-6 is associated with various autoimmune diseases, like multiple sclerosis. Methods. 134 patients with HLAB27 positive iridocyclitis, 84 patients with intermediate uveitis, 132 controls, and 65 HLAB27 positive controls were recruited for the present case-control study. Main outcome measures were genotype distribution and allelic frequencies determined by polymerase chain reaction. Results. The frequency of carriers of the minor allele for rs1800795 was significantly higher in patients with intermediate uveitis compared to controls (p = 0.04; OR: 1.46; CI: 1.02–2.11). Frequencies of the minor allele for rs1800795 did not differ significantly in patients with HLAB27 associated uveitis when compared to controls (p > 0.05). Conclusion. These findings further deepen our understanding of the commonality between multiple sclerosis and intermediate uveitis. Given the functionality of the investigated polymorphism, new pathophysiological insights are gained that help to evaluate possible therapeutic targets.

Abstract
Use of phyto-medicine and digitalization of phyto-compounds has been fallen enthralling field of science in recent years. Quercetin, a flavonoid with brilliant citron yellow pigment, is typically found in fruits and leafy vegetables in reasonable amount. Quercetin's potentials as an antioxidant, immune-modulator, antiinflammatory, anti-cancer, and others have been the subject of interest in this review. Although, profiling the insights in to the molecular characterization of quercetin with various targets provided the loop-holes in understanding the knowledge for the aforementioned mechanisms, still necessitates research globally to unearth it completely. Thus, the available science on the synthesis and significant role played by the old molecule - quercetin which does wonders even now have been vividly explained in the present review to benefit the scientific community.

Effect of 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol on Immune Functions in Healthy Adults in a Randomized Controlled Trial. Immune Netw 2015; 15:150-60. [PMID: 26140047 PMCID: PMC4486778 DOI: 10.4110/in.2015.15.3.150] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2015] [Revised: 06/01/2015] [Accepted: 06/08/2015] [Indexed: 12/01/2022] Open
Abstract
We previously reported that 1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol (PLAG) accelerates hematopoiesis and has an improving effect on animal disease models such as sepsis and asthma. The effects of PLAG supplementation on immune modulation were assessed in healthy men and women. The objective was to evaluate the effects of PLAG supplementation on immune regulatory functions such as activities of immune cells and cytokine production. A randomized double blind placebo-controlled trial was conducted. Seventy-five participants were assigned to one of two groups; all participants had an appropriate number of white blood cells on the testing day. The PLAG group (n=27) received oral PLAG supplements and the control group (n=22) received oral soybean oil supplements. IL-4 and IL-6 production by peripheral blood mononuclear cells (PBMC) were lower (p<0.001 and p<0.001, respectively) with PLAG than with soybean oil. However, the production of IL-2 and IFN-γ by PBMC was unaltered with PLAG supplementation. The B cell proliferation decreased significantly in the PLAG group compared to the soybean oil control (p<0.05). The intake of PLAG in healthy adults for 4 weeks was deemed safe. These data suggest that PLAG has an immunomodulatory function that inhibits the excessive immune activity of immunological disorders such as atopic and autoimmune diseases. PLAG could improve the condition of these diseases safely as a health food supplement.

Abstract
The prevalence of rheumatoid arthritis (RA) is 0.19%–0.41% in Chinese population. RA exerts profound influence on health-related quality of life (HRQoL), which imposed huge burdens on patients physically, mentally, and economically. As a developing country, People’s Republic of China faces enormous challenges in management of RA. Conventional-synthesized disease-modifying antirheumatic drugs (csDMARDs) remain the most selective therapeutic options for RA in People’s Republic of China owing to their affordable price and fair efficacy as well as tolerability. Unfortunately, there are substantial RA patients who are poor responders to csDMARDs, even to subsequently combined therapy with tumor necrosis factor antagonist (anti-TNF). Tocilizumab (TCZ) has been approved as a subsequent-line biological agent in patients with moderate-to-severe RA worldwide including People’s Republic of China. TCZ is the first biological agent approved for the treatment of RA inhibiting interlukin-6 (IL-6) by blocking both membrane-bound and soluble IL-6 receptors. Open-label studies in real-life practice and strictly controlled clinical trials demonstrated its high efficacy and safety profile in treatment of patients with RA who have inadequate responses to csDMARDs and anti-TNF. HRQoL of RA patients was improved in various measurements. TCZ was associated with 1.2 times the risk of adverse events, such as infections, dyslipidemia, and hepatic transaminases elevation, compared with pooled placebo. A relatively long half-life allowing for monthly intravenous administration and a newly developed subcutaneous injection make TCZ more acceptable. However, data are not enough so far comparing TCZ to anti-TNF. Lack of evidence in Chinese patients and high cost of TCZ limit its prescription in People’s Republic of China being a developing country. Further clinical trials and post-marketing surveillance may offer a comprehensive assessment of patient satisfaction and acceptability, which may help us define the optimal role for TCZ in therapeutic strategy.
