Cell Biol Int 2023; 47:754-767. [PMID: 36542640 DOI: 10.1002/cbin.11980] [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: 09/02/2022] [Revised: 11/16/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022]
Abstract
Inflammation and fibrosis are highly correlated with the progression of calcific aortic valve disease (CAVD). As one of the differentiated forms of valvular interstitial cells, myofibroblasts play a critical role in CAVD's development as do macrophages. Although numerous studies have been conducted on them separately, their communication and interaction remain unclear. We used porcine aortic valves to isolate valve interstitial cells (VICs). VICs were induced to differentiate into myofibroblasts by transforming growth factor-β1 (TGF-β1). After successful activation was determined, the myofibroblast-conditioned medium (CM) was collected and used to act on RAW264.7, a macrophage cell line. A migration and adhesion assay estimated the recruitment capability of myofibroblasts on macrophages. We used flow cytometry, quantitative polymerase chain reaction (qPCR), and Western blot analysis to investigate myofibroblasts' polarity promotion function in macrophages. Finally, we used macrophage-CM on VICs to explore the differentiation induction function of polarized macrophages. Myofibroblast marker alpha-smooth muscle actin and M2 macrophage marker CD163 were detected as upregulated in CAVD patients, and their expression has a certain correlation. The Smad3/HA/CD44 axis activated the differentiation of myofibroblasts by Western blot. The myofibroblast-CM can promote chemotaxis and adhesion of macrophages through protein kinase B/chemokine (C-C motif) ligand5 and Smad3/HA/CD44, respectively. Hyaluronic acid (HA) inside the myofibroblast-CM stimulates macrophages to polarize into M2 macrophages. In turn, M2 macrophage-CM has the promotive ability to activate myofibroblasts but fails to induce the osteoblast differentiation of VICs directly. The crosstalk between myofibroblasts and macrophages causes the excessive activation of myofibroblasts. This positive feedback loop may play a vital role in CAVD progression.

Abstract
Atherosclerosis chiefly results from inflammation as well as vascular endothelial cell dysfunction. Methylation levels of neuronally expressed developmentally downregulated 4 (NEDD4) were found to be fortified in atherosclerosis patients and NEDD4 deficiency enhanced vascular calcification. However, the exact function of NEDD4 in inflammation and vascular endothelial dysfunction remains to be elucidated. In the present study, CCK-8 assay was used to estimate cell viability. Reverse transcription-quantitative PCR was adopted to examine the expression of NEDD4, inflammation-associated enzymes and apurinic/apyrimidinic endodeoxyribonuclease 1 (APEX1). Western blotting was used to test NEDD4, endothelial nitric oxide synthase, inducible nitric oxide synthase and APEX1 protein levels. Cytotoxicity was detected by a lactate dehydrogenase (LDH) kit. Reactive oxygen species level was tested by a corresponding kit. Vascular cell adhesion molecule 1 and intercellular adhesion molecule 1 contents were examined with ELISA. Cell adhesion assays evaluated the adhesion of endothelial cells. Co-immunoprecipitation assay was used to test the relationship between NEDD4 and APEX1. The data revealed that NEDD4 expression rapidly declined in oxidized low density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs). Following NEDD4 overexpression, the active damage, inflammatory release and endothelial cell dysfunction in ox-LDL-induced HUVECs were attenuated. After co-transfection of APEX1 interference plasmids and NEDD4 overexpression plasmids, cell damage, inflammatory release and endothelial cell dysfunction in ox-LDL-induced HUVECs were improved again. Taken together, NEDD4 attenuated ox-LDL-induced inflammation and endothelial dysfunction by regulating APEX1 expression.

Abstract
Cardiovascular diseases (CVDs), the most common cause of mortality in rich countries, include a wide variety of pathologies of the heart muscle and vascular system that compromise the proper functioning of the heart. Most of the risk factors for cardiovascular diseases are well-known: lipid disorders, high serum LDL cholesterol, hypertension, smoking, obesity, diabetes, male sex and physical inactivity. Currently, much evidence shows that: (i) the human microbiota plays a crucial role in maintaining the organism’s healthy status; and (ii) a link exists between microbiota and cardiovascular function that, if dysregulated, could potentially correlate with CVDs. This scenario led the scientific community to carefully analyze the role of the microbiota in response to drugs, considering this the right path to improve the effectiveness of disease treatment. In this review, we examine heart diseases and highlight how the microbiota actually plays a preponderant role in their development. Finally, we investigate pharmacomicrobiomics—a new interesting field—and the microbiota’s role in modulating the response to drugs, to improve their effectiveness by making their action targeted, focusing particular attention on cardiovascular diseases and on innovative potential treatments.

Abstract
Leprosy may present kidney and endothelial abnormalities, being a risk factor for complications. However, the involvement of renal and vascular endothelia has been poorly investigated. We aimed to investigate if the levels of systemic endothelial biomarkers are associated with kidney abnormalities and the clinical forms of leprosy. This is a cross-sectional study with leprosy patients enrolled in January 2017 to December 2018, before the initiation of the multidrug therapy. Leprosy-associated clinical and epidemiological data were collected. Two groups were investigated: Paucibacillary (PB) and Multibacillary (MB) infections, for the comparisons. Serum and urine samples were obtained for laboratory analysis. In serum samples, were evaluated the endothelial biomarkers VCAM-1 and ICAM-1. In total, 101 leprosy patients were included, the mean age was 48±١٥ years and 71 (70%) were male. The multibacillary form occurred in 81 cases (80%), among which 22 had the Virchowian form. Serum creatinine was more elevated in the MB group than in PB patients. In addition, VCAM-1 was elevated in the MB group and was correlated with the bacteriological index (rho = 0.372, p <0.01), the duration of disease symptoms (rho = 0.234, p = 0.04), and the number of skin lesions (rho = 0.468, p <0.001). Moreover, in MB patients who presented albuminuria >15 mg/g of creatinine, VCAM-1 showed a significant correlation with increased albuminuria and improved the correlation with the number of skin lesions (rho= 0.563, p=0.010). In conclusion, higher systemic VCAM-1 levels were associated with the multibacillary clinical form of leprosy and with increased albuminuria. Prospective studies are necessary to establish a cause-effect and evaluate the preventive role of these biomarkers to improve the clinical care.

Abstract
Mycobacterium leprae, the causative agent of leprosy, is still actively transmitted in endemic areas reflected by the fairly stable number of new cases detected each year. Recognizing the signs and symptoms of leprosy is challenging, especially at an early stage. Improved diagnostic tools, based on sensitive and specific biomarkers, that facilitate diagnosis of leprosy are therefore urgently needed. In this review, we address the challenges that leprosy biomarker research is facing by reviewing cell types reported to be involved in host immunity to M leprae. These cell types can be associated with different possible fates of M leprae infection being either protective immunity, or pathogenic immune responses inducing nerve damage. Unraveling these responses will facilitate the search for biomarkers. Implications for further studies to disentangle the complex interplay between host responses that lead to leprosy disease are discussed, providing leads for the identification of new biomarkers to improve leprosy diagnostics.

Abstract
BACKGROUND Macrophages are the main players involved in inflammation. Intercellular adhesion molecule-1 (ICAM-1) facilitates macrophage polarization prior to extravasation into inflamed tissue. Piperine, a natural product derived from black pepper, possesses useful biological and pharmacological activities. In the current study, the possible anti-inflammatory effect of piperine on the expression of ICAM-1 on J774.1 murine macrophage cell line was investigated. METHODS Lipopolysaccharide (LPS)-stimulated J774.1 cells were cultured in the presence of different concentrations of piperine to examine the changes in ICAM-1 expression by real-time PCR and flow cytometry. RESULTS We found that piperine decreased ICAM-1 gene expression level from 2.4 ± 0.25 RFC (relative fold change) in LPS-only treated cells to 0.85 ± 0.525 RFC at 1µg/ml (p<0.05), 0.43 ± 0.27 RFC at 10µg/ml (p<0.01), and 0.26 ± 0.25 RFC at 20µg/ml (p<0.01). In flow cytometry, piperine at all concentrations significantly decreased ICAM-1 surface expressions (P<0.05). The geometric mean fluorescence intensity (g-MFI) in LPS-only treated cells (792 ± 57.3) decreased to 482±70 g-MFI at 20 μg/ml piperine. CONCLUSION According to the results of this study, by decreasing the expression of ICAM-1, piperine has been suggested to reduce inflammation and have the potential to provide therapeutic benefits for immune-mediated diseases.

Abstract
Leprosy is a disease caused by Mycobacterium leprae (ML) with diverse clinical manifestations, which are strongly correlated with the host's immune response. Skin lesions may be accompanied by peripheral neural damage, leading to sensory and motor losses, as well as deformities of the hands and feet. Both innate and acquired immune responses are involved, but the disease has been classically described along a Th1/Th2 spectrum, where the Th1 pole corresponds to the most limited presentations and the Th2 to the most disseminated ones. We discuss this dichotomy in the light of current knowledge of cytokines, Th subpopulations and regulatory T cells taking part in each leprosy presentation. Leprosy reactions are associated with an increase in inflammatory activity both in limited and disseminated presentations, leading to a worsening of previous symptoms or the development of new symptoms. Despite the efforts of many research groups around the world, there is still no adequate serological test for diagnosis in endemic areas, hindering the eradication of leprosy in these regions.

Abstract
Intravenous artesunate is effective against cerebral malaria (CM), but high mortality and neurological sequelae in survivors are inevitable. We investigated the effect of combined artesunate and tetramethylpyrazine using mouse models of experimental cerebral malaria (ECM). Artesunate + tetramethylpyrazine reduced microvascular blockage and improved neurological function, including the rapid murine coma and behavior scale (RMCBS), leading to improved survival and reduced pathology in ECM. This combination downregulated the expression of adhesion molecules and sequestration of parasitized red blood cells (pRBCs), increased cerebral blood flow, nerve growth factor (b-NGF), vascular endothelial growth factor A (VEGF-A), and neurotrophin (brain-derived neurotrophic factor (BDNF), neurotrophic factor-3 (NT-3)) levels, and alleviated hippocampal neuronal damage and astrocyte activation. Down- (n = 128) and upregulated (n = 64) proteins were identified in the artesunate group, while up- (n = 217) and downregulated (n = 177) proteins were identified in the artesunate + tetramethylpyrazine group, presenting a significantly altered proteome profile. KEGG analysis showed that 166 differentially expressed proteins were enriched in the Art group and 234, in the artesunate + tetramethylpyrazine group. The neuroprotective effects of artesunate + tetramethylpyrazine were mainly related to proteins involved in axon development and transportation between blood and brain. These results suggested that artesunate + tetramethylpyrazine could be a potential adjuvant therapy against CM, but this will have to be confirmed in future studies and trials.

Abstract
Calcific aortic valve disease (CAVD) is the most frequent heart valve disorder. It is characterized by an active remodeling process accompanied with valve mineralization, that results in a progressive aortic valve narrowing, significant restriction of the valvular area, and impairment of blood flow.The pathophysiology of CAVD is a multifaceted process, involving genetic factors, chronic inflammation, lipid deposition, and valve mineralization. Mineralization is strictly related to the inflammatory process in which both, innate, and adaptive immunity are involved. The underlying pathophysiological pathways that go from inflammation to calcification and, finally lead to severe stenosis, remain, however, incompletely understood. Histopathological studies are limited to patients with severe CAVD and no samples are available for longitudinal studies of disease progression. Therefore, alternative routes should be explored to investigate the pathogenesis and progression of CAVD.Recently, increasing evidence suggests that epigenetic markers such as non-coding RNAs are implicated in the landscape of phenotypical changes occurring in CAVD. Furthermore, the microbiome, an essential player in several diseases, including the cardiovascular ones, has recently been linked to the inflammation process occurring in CAVD. In the present review, we analyze and discuss the CAVD pathophysiology and future therapeutic strategies, focusing on the real and putative role of inflammation, calcification, and microbiome.

Abstract
The skin is an organ harboring several types of immune cells that participate in innate and adaptive immune responses. The immune system of the skin comprises both skin cells and professional immune cells that together constitute what is designated skin-associated lymphoid tissue (SALT). In this review, I extensively discuss the organization of SALT and the mechanisms involved in its responses to infectious diseases of the skin and mucosa. The nature of these SALT responses, and the cellular mediators involved, often determines the clinical course of such infections. I list and describe the components of innate immunity, such as the roles of the keratinocyte barrier and of inflammatory and natural killer cells. I also examine the mechanisms involved in adaptive immune responses, with emphasis on new cytokine profiles, and the role of cell death phenomena in host-pathogen interactions and control of the immune responses to infectious agents. Finally, I highlight the importance of studying SALT in order to better understand host-pathogen relationships involving the skin and detail future directions in the immunological investigation of this organ, especially in light of recent findings regarding the skin immune system.

Abstract
The use of engineered cardiac tissues (ECTs) is a new strategy for the repair and replacement of cardiac tissues in patients with myocardial infarction, particularly at late stages. However, the mechanisms underlying the development of ECTs, including cell-scaffold interactions, are not fully understood, although they are closely related to their therapeutic effect. In the present study, we aimed to determine the cellular fate of cardiomyocytes in a 3D scaffold microenvironment, as well as their role in generating the cellular diversity of ECTs by single-cell sequencing analysis. Consistent with the observed plasticity of cardiomyocytes during cardiac regeneration, cardiomyocytes in 3D scaffolds appeared to dedifferentiate, showing an initial loss of normal cytoskeleton organization in the adaptive response to the new scaffold microenvironment. Cardiomyocytes undergoing this process regained their proliferation potential and gradually developed into myocardial cells at different developmental stages, generating heterogeneous regenerative ECTs. To better characterize the remodeled ECTs, high-throughput single-cell sequencing was performed. The ECTs contained a wide diversity of cells related to endogenous classes in the heart, including myocardial cells at different developmental stages and different kinds of interstitial cells. Non-cardiac cells seemed to play important roles in cardiac reconstruction, especially Cajal-like interstitial cells and macrophages. Altogether, our results showed for the first time that cells underwent adaptive dedifferentiation for survival in a 3D scaffold microenvironment to generate heterogeneous tissues. These findings provide an important basis for an improved understanding of the development and assembly of engineered tissues.

Abstract
AbstractLeprosy is a granulomatous disease, infectious and transmissible, which affects the skin and peripheral nerves, havingMycobacterium lepraeas causative agent. The manifestation of this disease causes cutaneous lesions, peripheral neuropathies and, in more extreme cases, may generate deformities and disabilities in affected individuals. Patents were identified using the descriptor ‘leprosy’ and code A61K of the international patent classification, which indicates only products that meet human needs. The analysis was made using theWIPO,ESPACENETandUSPTOdatabases, until the month of September 2016. Through this review, we found a variety of in vitro, pre-clinical and clinical studies relating to the treatment of leprosy with different types of compounds and forms of administration. New treatment proposals should include pain reduction capabilities, prevention or limitation of the appearance of cutaneous lesions, as well as prevention of the progression of the disease to more severe stages that may lead to loss of function or potentiate the individual's immune response to theM. lepraebacillus in order to prevent bacterial spread. We concluded that any patents developed with natural products were not found in the treatment of leprosy. All the deposited products were synthetic origin, mostly tested in humans and of varied forms of administration.

Abstract
Macrophages are among the main cells involved in generation of inflammation. To investigate the anti-inflammatory effect of Satureja hortensis (summer savory), lipopolysaccharide (LPS)-activated J774.1 macrophages were treated with various extracts, and the expression and release of various inflammatory molecules by macrophages were examined. We showed that dichloromethane and hexane extracts reduced nitric oxide (NO) production more efficiently than other extracts. Both extracts decreased gene expression of inducible NO synthase (iNOS) (<0.44 fold of control), cyclooxygenase (COX)-2 (<0.29 fold), interleukin (IL)-1β (<0.41 fold), IL-6 (<0.25 fold) and tumor necrosis factor (TNF)-α (<0.2 fold). The extracts reduced IL-6 and IL-1β proteins production from macrophages. Surface intensity of expression of intercellular adhesion molecule (ICAM)-1 decreased to 845 ± 28.1 (dichloromethane) and 715 ± 48.6 (hexane) compared to the control (902 ± 73.1). These findings showed that Satureja hortensis, by influencing macrophages and related mediators, could contribute to reduction of inflammation and might be useful as an anti-inflammatory agent.
