Persistent transcriptional changes in cardiac adaptive immune cells following myocardial infarction: New evidence from the re-analysis of publicly available single cell and nuclei RNA-sequencing data sets. J Mol Cell Cardiol 2024; 192:48-64. [PMID: 38734060 DOI: 10.1016/j.yjmcc.2024.04.016] [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: 07/14/2023] [Revised: 03/17/2024] [Accepted: 04/29/2024] [Indexed: 05/13/2024]
Abstract
INTRODUCTION Chronic immunopathology contributes to the development of heart failure after a myocardial infarction. Both T and B cells of the adaptive immune system are present in the myocardium and have been suggested to be involved in post-MI immunopathology. METHODS We analyzed the B and T cell populations isolated from previously published single cell RNA-sequencing data sets (PMID: 32130914, PMID: 35948637, PMID: 32971526 and PMID: 35926050), of the mouse and human heart, using differential expression analysis, functional enrichment analysis, gene regulatory inferences, and integration with autoimmune and cardiovascular GWAS. RESULTS Already at baseline, mature effector B and T cells are present in the human and mouse heart, having increased activity in transcription factors maintaining tolerance (e.g. DEAF1, JDP2, SPI-B). Following MI, T cells upregulate pro-inflammatory transcript levels (e.g. Cd11, Gzmk, Prf1), while B cells upregulate activation markers (e.g. Il6, Il1rn, Ccl6) and collagen (e.g. Col5a2, Col4a1, Col1a2). Importantly, pro-inflammatory and fibrotic transcription factors (e.g. NFKB1, CREM, REL) remain active in T cells, while B cells maintain elevated activity in transcription factors related to immunoglobulin production (e.g. ERG, REL) in both mouse and human post-MI hearts. Notably, genes differentially expressed in post-MI T and B cells are associated with cardiovascular and autoimmune disease. CONCLUSION These findings highlight the varied and time-dependent dynamic roles of post-MI T and B cells. They appear ready-to-go and are activated immediately after MI, thus participate in the acute wound healing response. However, they subsequently remain in a state of pro-inflammatory activation contributing to persistent immunopathology.

Abstract
T lymphocytes play a crucial role in adaptive immunity. Dysregulation of T cell-derived inflammatory cytokine expression and loss of self-tolerance promote inflammation and tissue damage in several autoimmune/inflammatory diseases, including systemic lupus erythematosus (SLE) and psoriasis. The transcription factor cAMP responsive element modulator α (CREMα) plays a key role in the regulation of T cell homeostasis. Increased expression of CREMα is a hallmark of the T cell-mediated inflammatory diseases SLE and psoriasis. Notably, CREMα regulates the expression of effector molecules through trans-regulation and/or the co-recruitment of epigenetic modifiers, including DNA methyltransferases (DNMT3a), histone-methyltransferases (G9a) and histone acetyltransferases (p300). Thus, CREMα may be used as a biomarker for disease activity and/or target for future targeted therapeutic interventions.

Abstract
BACKGROUND Increased inflammatory mediators produced by inflamed cells are often connected with pressure-induced cardiac remodelling and heart failure. Interleukin-21 (IL-21) serves as an immunomodulator involved in multiple pathological processes, while the role of IL-21 in pressure-induced cardiac remodelling remains unclear. EXPERIMENT APPROACH Cardiac function, CD4+T-cell infiltration, and IL-21 and IL-21 receptor expression levels were investigated in a pressure overload mouse model induced by aortic banding (AB) surgery. Western blotting and qPCR were used to detect the effects of IL-21 on inflammation, apoptosis, and fibrosis in the myocardium after AB surgery. In addition, the signal transduction mechanisms underlying these effects were investigated in vivo and in vitro by qPCR and western blotting. KEY RESULTS IL-21 levels in mice rapidly increased in the acute phase after AB surgery. Compared with those in the control group, the transverse aortas of mice in the AB surgery group contracted. However, it must be noted that neutralizing IL-21 could reduce myocardial injury and remodelling, while the administration of exogenous IL-21 recombinant protein had the opposite effect. Mechanistically, we learned that IL-21 is effective in inducing the activation of tissue inhibitor of metalloproteinase 4 (TIMP4) and matrix metalloproteinase 9 (MMP-9) signalling in vitro and in vivo. We believe that increased activation and secretion of IL-21 and CD4+ T cells may contribute to stress overload-induced cardiac remodelling. CONCLUSION These findings reveal a novel mechanism by which IL-21 stimulates myocardial inflammation, apoptosis, and fibrosis to induce stress-overload-induced myocardial remodelling by activating the TIMP4/MMP9 signalling pathway.

Abstract
OBJECTIVE Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease of unknown origin. The regulation of inflammatory processes involves multiple cellular steps including mRNA transcription and translation. Different miRNAs tightly control these processes. We aimed to determine the roles of specific miRNAs within JIA pathogenesis. METHODS We performed a global miRNA expression analysis in parallel in cells from the arthritic joint and peripheral blood of oligoarticular JIA patients and healthy controls. QRT-PCR analysis was used to verify expression of miRNA in T cells. Ex vivo experiments and flow cytometric analyses were used to analyze proliferation and redox metabolism. RESULTS Global miRNA expression analysis demonstrated a different composition of miRNA expression at the site of inflammation compared with peripheral blood. Bioinformatic analysis of predicted miRNA target genes suggest a huge overrepresentation of genes involved in metabolic and oxidative stress pathways in the inflamed joint. Despite enhanced ROS levels within the local inflammatory milieu, JIA T cells are hyperproliferative and reveal an overexpression of miR-23a, which is an inhibitor of PPIF, the regulator of mitochondrial ROS escape. Mitochondrial ROS escape is diminished in JIA T cells resulting in their prolonged survival. CONCLUSION Our data suggest that miRNA dependent mitochondrial ROS shuttling might be a mechanism that contributes to T cell regulation in JIA at the site of inflammation.

Abstract
We recently reported that the risk of sexually acquired HIV-1 infection is increased significantly by variants in the gene encoding CD101, a protein thought to modify inflammatory responses. Using blood samples from individuals with and without these variants, we demonstrate that CD101 variants modify the prevalence of circulating inflammatory cell types and show that CD101 variants are associated with increased proinflammatory cytokine production by circulating T cells. One category of CD101 variants is associated with a reduced capacity of regulatory T cells to suppress T cell cytokine production, resulting in a reduction in the baseline level of immune quiescence. These data are supported by transcriptomics data revealing alterations in the intrinsic regulation of antiviral pathways and HIV resistance genes in individuals with CD101 variants. Our data support the hypothesis that CD101 contributes to homeostatic regulation of bystander inflammation, with CD101 variants altering heterosexual HIV-1 acquisition by facilitating increased prevalence and altered function of T cell subsets.

Abstract
Background: Gonadotropin-releasing hormone analogs (GnRHas) are used for treating central precocious puberty (CPP). However, their roles in the regulation of immune cells especially regulatory T cells (Tregs) remains elusive. Therefore, we characterized buserelin-induced phenotypical and functional changes of Tregs.Methods: A rat CPP model was established followed by administration of buserelin acetate. Flow cytometry was used to evaluate the expression of functional molecules in splenic Tregs. The suppressive activity of Tregs was determined by the suppression assay. GnRHR expression in Tregs was assessed by flow cytometry analysis and Immunoblotting. Normal Tregs were then stimulated and treated with buserelin acetate in vitro. After that, Foxp3 expression, Treg proliferation, and cytokine production were analyzed by flow cytometry. Intracellular signaling was evaluated by Immunoblotting, and Treg function was determined by the suppression assay.Results: After in vivo buserelin treatment, the frequency of splenic Tregs was decreased, with the reduction in the expression of Foxp3, IL-10, and TGF-β. The suppressive activity of Tregs was weakened. Buserelin down-regulated Foxp3 expression while promoting the expression of RORγt and IL-17 in Tregs through activating the protein kinase A (PKA) pathway in vitro. The PKA inhibitor H-89 abolished the effect of buserelin and enhanced Treg function.Conclusion: Buserelin impaired the immunosuppressive activity of Tregs through the PKA signal pathway. Buserelin-induced activation of PKA signaling down-regulated Foxp3 expression while promoting RORγt expression in Tregs, and subsequently weakened Treg function. Our study indicates the necessity of monitoring Treg activity in CPP patients to avoid potential autoimmunity or inflammation.

Abstract
To determine the potential changes of IL-6, IL-17A and IL-21 levels during induction therapy, and to assess their relationship with disease activity and immunologic features on patients with active lupus nephritis, twenty-eight patients treated with corticosteroid and immunosuppressants were included in this study. Demographic, clinical, serological data and disease activity were assessed. Blood samples were collected at week 0, 12 and 24, and serum concentrations of IL-17A, IL-6 and IL-21 were measured by cytometric bead array. The serum concentrations of IL-6, IL-17A and IL-21 (P<0.001, P<0.01, P=0.001, respectively) decreased progressively during induction therapy. Concentration of IL-6, IL-17A and IL-21 was higher in non-remission group than that in remission group. A positive correlation was established between the concentration of these cytokines and the severity of proteinuria (P<0.001, P=0.020, P=0.045, respectively), ESR (P<0.001), SLEDAI scores (P<0.05), and ANA titers (P=0.018, P=0.048, P<0.05, respectively). Additionally, ROC curve analysis for IL-6, IL-17A and IL-21 was performed to predict the disease activity. The optimal cutoff level was 5.78 pg/ml, 1.98 pg/ml and 8.59 pg/ml, with AUC=0.809, 0.735 and 0.786. The concentration of IL-6 and IL-21 may be regarded as an indicator for the remission of active lupus nephritis, with cutoff value of 9.12 pg/ml and 11.30 pg/ml, while AUC=0.930 and 0.896. The production of serum IL-6, IL-17A and IL-21 in active LN was dramatically declined during induction therapy, which may improve disease activity while delay disease progression of LN.

Abstract
BACKGROUND Inflammatory effector T cells trigger inflammation despite increased numbers of Treg cells in the synovial joint of patients suffering from juvenile idiopathic arthritis (JIA). The cAMP response element (CREM)α is known to play a major role in regulation of T cells in SLE, colitis, and EAE. However, its role in regulation of effector T cells within the inflammatory joint is unknown. METHODS CREM expression was analyzed in synovial fluid cells from oligoarticular JIA patients by flow cytometry. Peripheral blood mononuclear cells were incubated with synovial fluid and analyzed in the presence and absence of CREM using siRNA experiments for T cell phenotypes. To validate the role of CREM in vivo, ovalbumin-induced T cell dependent arthritis experiments were performed. RESULTS CREM is highly expressed in synovial fluid T cells and its expression can be induced by treating healthy control PBMCs with synovial fluid. Specifically, CREM is more abundant in CD161+ subsets, than CD161- subsets, of T cells and contributes to cytokine expression by these cells. Finally, development of ovalbumin-induced experimental arthritis is ameliorated in mice with adoptively transferred CREM-/- T cells. CONCLUSION In conclusion, our study reveals that beyond its role in SLE T cells CREM also drives an inflammatory phenotype of T cells in JIA.
