Abstract
T-helper cytokines interferon gamma (IFNɣ), interleukin 17 (IL-17) and IL-10 impact systemic lupus erythematosus (SLE) directly and indirectly via modulation of autoAb production. We determined the separate and combined effects on clinical manifestations of SLE (N = 62). IFNɣ, IL-17 but not IL-10 were significantly elevated in patients with SLE. IFNɣ positively correlated with anti-DNA and anti-SSA. IL-17 positively correlated with anti-SSA and was significantly higher in patients with discoid rash and class V LN. IL-10 did not correlate with circulating autoantibodies but was significantly elevated in patients with LN. Patients with LN had elevated plasma levels of anti-DNA and anti-Sm/ribonuclear protein (RNP). Anti-Sm/RNP levels were decreased in patients with acute mucocutaneous manifestations, including photosensitivity and/or malar rash. The study provides critical insights into pathological mechanisms of LN, which could help guide future diagnoses and therapies.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that associates with aberrant activation of B lymphocytes and excessive autoantibodies. Interleukin 10 (IL-10)/interleukin 35 (IL-35) and IL-10/IL-35-producing regulatory B cells have been demonstrated to possess immunosuppressive functions during systemic lupus erythematosus. Here, we detected the proportion of CD19+CD24highCD27+ B cells as well as IL-10 and IL-35 levels in peripheral blood of SLE patients and healthy individuals, and investigated their relations with clinical features of SLE. METHODS 41 SLE patients and 25 healthy controls were recruited. The patients were divided into groups based on SLEDAI score, anti-dsDNA antibody, rash, nephritis and hematological disorder. Flow cytometry was used to detect the proportion of CD24hiCD27+ B cells. ELISA was used to detect serum levels of IL-10 and IL-35. RESULTS Our results showed that the CD19+CD24highCD27+ B population was decreased in active SLE patients, and anti-correlated with the disease activity. Of note, we found significant increase of IL-10 and decrease of IL-35 in SLE patients with disease activity score > 4, lupus nephritis or hematological disorders compared to those without related clinical features. CONCLUSIONS Reduced CD19+CD24highCD27+ B cells expression may be involved in the pathogenesis of SLE. Moreover, we supposed that IL-35 instead of IL-10 played a crucial role in immune regulation during SLE disease.

Expression of Eosinophilic Subtype Markers in Patients with Kawasaki Disease. Int J Mol Sci 2022; 23:ijms231710093. [PMID: 36077487 PMCID: PMC9456171 DOI: 10.3390/ijms231710093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 08/12/2022] [Accepted: 08/30/2022] [Indexed: 11/17/2022] Open
Abstract
PURPOSE Eosinophils may rise to a higher level in the acute phase of Kawasaki disease (KD) both before and after intravenous immunoglobulin (IVIG) therapy. A substantial body of research was carried out on the association between KD and allergic diseases. Eosinophils play an important role in type 2 inflammation. Recent studies have shown that there are two distinct subtypes of eosinophils. In addition to their role in inflammation, lung-resident eosinophils (rEOS) also regulate homeostasis. Inflammatory eosinophils (iEOS) reflect type 2 inflammation in tissues. iEOS were considered the primary eosinophils in non-severe allergic asthma, while rEOS were thought to be the primary eosinophils in severe non-allergic eosinophilic asthma. This case-control study aimed to investigate the marker expression of eosinophilic subtypes in KD patients. MATERIALS AND METHODS The marker expressions of eosinophilic subtypes in the leukocytes of patients with KD were evaluated by the recently established KDmarkers online tool, a web server including gene expression data. Finally, the results were validated with a quantitative reverse transcriptase polymerase chain reaction (RT-PCR). We analyzed the mRNA expression levels of SELL and IL10RA in leukocytes from KD patients and febrile children. RESULTS Included in our screening tools were transcriptome arrays, which provided clues showing the importance of rEOS, whose role was identified by three genes (lower IL10RA, higher SELL, and SERPINB1 than controls). In contrast, the iEOS representative gene CD101 was not elevated in KD. It was found that the gene IL10RA, a marker of inflammatory eosinophilic leukocytes, was more highly expressed in the leukocytes of KD patients (n = 43) than febrile controls (n = 32), especially those without coronary artery lesions (CAL) (n = 26). Before treatment, SELL expression was higher in leukocytes of CAL patients (CAL, 1.33 ± 0.18, n = 39; non-CAL, 0.87 ± 0.12, n = 55; p = 0.012). SELL was significantly higher after half a year compared to febrile controls. CONCLUSIONS To our knowledge, this is the first study to demonstrate that KD patients have increased SELL than febrile controls after 6 months of treatment. We present evidence here that dynamically different eosinophilic involvement exists between KD patients with and without CAL. The role of eosinophilic subtypes in KD patients warrants further investigation.

Tissue-based IL-10 signalling in helminth infection limits IFNγ expression and promotes the intestinal Th2 response. Mucosal Immunol 2022; 15:1257-1269.

Abstract
Type 2 immunity is activated in response to both allergens and helminth infection. It can be detrimental or beneficial, and there is a pressing need to better understand its regulation. The immunosuppressive cytokine IL-10 is known as a T helper 2 (Th2) effector molecule, but it is currently unclear whether IL-10 dampens or promotes Th2 differentiation during infection. Here we show that helminth infection in mice elicits IL-10 expression in both the intestinal lamina propria and the draining mesenteric lymph node, with higher expression in the infected tissue. In vitro, exogenous IL-10 enhanced Th2 differentiation in isolated CD4+ T cells, increasing expression of GATA3 and production of IL-5 and IL-13. The ability of IL-10 to amplify the Th2 response coincided with its suppression of IFNγ expression and in vivo we found that, in intestinal helminth infection, IL-10 receptor expression was higher on Th1 cells in the small intestine than on Th2 cells in the same tissue, or on any Th cell in the draining lymph node. In vivo blockade of IL-10 signalling during helminth infection resulted in an expansion of IFNγ+ and Tbet+ Th1 cells in the small intestine and a coincident decrease in IL-13, IL-5 and GATA3 expression by intestinal T cells. These changes in Th2 cytokines correlated with reduced expression of type 2 effector molecules, such as RELMα, and increased parasite egg production. Together our data indicate that IL-10 signalling promotes Th2 differentiation during helminth infection at least in part by regulating competing Th1 cells in the infected tissue.

Abstract
Systemic lupus erythematosus (SLE) is a disease characterized by dysregulation and hyperreactivity of the immune response at various levels, including hyperactivation of effector cell subtypes, autoantibodies production, immune complex formation, and deposition in tissues. The consequences of hyperreactivity to the self are systemic and local inflammation and tissue damage in multiple organs. Lupus nephritis (LN) is one of the most worrying manifestations of SLE, and most patients have this involvement at some point in the course of the disease. Among the effector cells involved, the Th17, a subtype of T helper cells (CD4+), has shown significant hyperactivation and participates in kidney damage and many other organs. Th17 cells have IL-17A and IL-17F as main cytokines with receptors expressed in most renal cells, being involved in the activation of many proinflammatory and profibrotic pathways. The Th17/IL-17 axis promotes and maintains repetitive tissue damage and maladaptive repair; leading to fibrosis, loss of organ architecture and function. In the podocytes, the Th17/IL-17 axis effects include changes of the cytoskeleton with increased motility, decreased expression of health proteins, increased oxidative stress, and activation of the inflammasome and caspases resulting in podocytes apoptosis. In renal tubular epithelial cells, the Th17/IL-17 axis promotes the activation of profibrotic pathways such as increased TGF-β expression and epithelial-mesenchymal transition (EMT) with consequent increase of extracellular matrix proteins. In addition, the IL-17 promotes a proinflammatory environment by stimulating the synthesis of inflammatory cytokines by intrinsic renal cells and immune cells, and the synthesis of growth factors and chemokines, which together result in granulopoiesis/myelopoiesis, and further recruitment of immune cells to the kidney. The purpose of this work is to present the prognostic and immunopathologic role of the Th17/IL-17 axis in Kidney diseases, with a special focus on LN, including its exploration as a potential immunotherapeutic target in this complication.

CD4+ T cell expression of the IL-10 receptor is necessary for facial motoneuron survival after axotomy. J Neuroinflammation 2020; 17:121.

Abstract
Background After peripheral nerve transection, facial motoneuron (FMN) survival depends on an intact CD4+ T cell population and a central source of interleukin-10 (IL-10). However, it has not been determined previously whether CD4+ T cells participate in the central neuroprotective IL-10 cascade after facial nerve axotomy (FNA). Methods Immunohistochemical labeling of CD4+ T cells, pontine vasculature, and central microglia was used to determine whether CD4+ T cells cross the blood-brain barrier and enter the facial motor nucleus (FMNuc) after FNA. The importance of IL-10 signaling in CD4+ T cells was assessed by performing adoptive transfer of IL-10 receptor beta (IL-10RB)-deficient CD4+ T cells into immunodeficient mice prior to injury. Histology and qPCR were utilized to determine the impact of IL-10RB-deficient T cells on FMN survival and central gene expression after FNA. Flow cytometry was used to determine whether IL-10 signaling in T cells was necessary for their differentiation into neuroprotective subsets. Results CD4+ T cells were capable of crossing the blood-brain barrier and associating with reactive microglial nodules in the axotomized FMNuc. Full induction of central IL-10R gene expression after FNA was dependent on CD4+ T cells, regardless of their own IL-10R signaling capability. Surprisingly, CD4+ T cells lacking IL-10RB were incapable of mediating neuroprotection after axotomy and promoted increased central expression of genes associated with microglial activation, antigen presentation, T cell co-stimulation, and complement deposition. There was reduced differentiation of IL-10RB-deficient CD4+ T cells into regulatory CD4+ T cells in vitro. Conclusions These findings support the interdependence of IL-10- and CD4+ T cell-mediated mechanisms of neuroprotection after axotomy. CD4+ T cells may potentiate central responsiveness to IL-10, while IL-10 signaling within CD4+ T cells is necessary for their ability to rescue axotomized motoneuron survival. We propose that loss of IL-10 signaling in CD4+ T cells promotes non-neuroprotective autoimmunity after FNA.

Abstract
The expression of cytokine receptors has a crucial role in many cellular processes. Recent studies reported that changes of receptor expression could control the action of mediators on target cells. The initiation of different signaling pathways and, therefore, specific effects on cells, depends on certain components forming the cytokine-receptor complex. These mechanisms control the immune response and affect both the course of diseases (oncological, autoimmune, inflammatory) and the effectiveness of therapy. This review describes the potential of immune mediator receptors to regulate the efficiency of cytokine activity during pathologic processes and ensure the variability of their biological effects. Our aim was to investigate the spectrum of potential roles of changes in mediator receptor expression for main classes of pathologies. For all major types of immune mediators (cytokines, interleukins, chemokines, growth factors, and tumor necrosis factors), it has been shown that changes in their receptor expression are associated with impaired functioning of the organism in chronic diseases.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is characterized by abnormal activated T cells, autoreactive B cells, and massive cytokines. The CD4+ T cells determined B-cells differentiation and cytokines production. The programmed death 1 (PD-1) is the checkpoint immunoinhibitory receptor of activated T cells, and its engagement could exhaust T cells. In this study, we investigated the role of PD-1 systemic engagement with PD-L1-Ig in lupus-like nephritis in SLE mice. METHODS The murine PD-L1-Ig was injected into SLE-prone mice. The proteinuria and survival ratio were monitored. The production of anti-dsDNA autoantibodies and cytokines in serum were measured by enzyme-linked immunosorbent assay. The cytokine-producing T cells (interferon-γ, IFN-γ and IL-17α) in kidney and spleen were detected with flowcytometry. The pathological evaluation of the Ig deposition in the glomeruliand was determined with immunofluorescence. Lymphocytes in 24-h urine were detected with flowcytometry. RESULTS The systemic administration of PD-L1-Ig activated PD-1-PD-L1 axis of CD4+ T lymphocytes, suppressed Th17 formation in many organs, including the spleen and the kidney, demolished abnormal production of cytokines (IFN-γ, IL-17, and IL-10) and anti-dsDNA autoantibodies in serum, inhibited immunoglobulin G deposition in the glomeruli with the decrease of proteinuria, and activated T cells in urine. Accordingly, the systemic conjugation of PD-L1-PD-1 impaired renal autoimmune injure and prolonged survival time. CONCLUSION Our research demonstrated that the protective function of systemic activation of PD-1-PD-L1 axis with PD-L1-Ig attenuates the nephritis in SLE-prone mice, which facilitates us to understand the suppressive function of PD-1-PD-L1 axis in the pathogenesis and progress of the lupus nephritis, and to explore a possible effective therapeutic strategy to SLE.

Abstract
IL-10 is a multifunctional cytokine secreted by a variety of cells. It not only inhibits activation of monocyte/macrophage system and synthesis of monocyte cytokine and inflammatory cytokine but also promotes the proliferation and maturation of non-monocyte-dependent T cell, stimulating proliferation of antigen-specific B cell. Increasing evidence indicates that IL-10 plays an important role in both the onset and development of auto-immune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), Sjogren's syndrome (SS), multiple sclerosis (MS), Crohn's disease (CD), and psoriasis. However, the exact mechanisms of IL-10 in auto-immune diseases remain unclear. In the present review, we will summarize the biological effects of IL-10, as well as its role and therapeutic potential in auto-immune diseases.

Abstract
The immune-regulatory cytokine IL-10 plays a central role during innate and adaptive immune responses. IL-10 is elevated in the serum and tissues of patients with systemic lupus erythematosus (SLE), an autoimmune disorder characterized by autoantibody production, immune-complex formation, and altered cytokine expression. Because of its B cell-promoting effects, IL-10 may contribute to autoantibody production and tissue damage in SLE. We aimed to determine molecular events governing T cell-derived IL-10 expression in health and disease. We link reduced DNA methylation of the IL10 gene with increased recruitment of Stat family transcription factors. Stat3 and Stat5 recruitment to the IL10 promoter and an intronic enhancer regulate gene expression. Both Stat3 and Stat5 mediate trans-activation and epigenetic remodeling of IL10 through their interaction with the histone acetyltransferase p300. In T cells from SLE patients, activation of Stat3 is increased, resulting in enhanced recruitment to regulatory regions and competitive replacement of Stat5, subsequently promoting IL-10 expression. A complete understanding of the molecular events governing cytokine expression will provide new treatment options in autoimmune disorders, including SLE. The observation that altered activation of Stat3 influences IL-10 expression in T cells from SLE patients offers molecular targets in the search for novel target-directed treatment options.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancer types worldwide. The signal transducer and activator of transcription 3 (STAT3) protein is a member of the STAT transcription factor family. Oncogenesis, invasion, and metastasis of HCC are associated with activation of STAT3. However, whether aberrant expression of phosphorylated STAT3 (p-STAT3) in peripheral CD4+ and CD8+ T cells relates to HCC pathogenesis remains unclear. In this study, the expression of p-STAT3 in CD4+ and CD8+ T cells, and the levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), IL-6 and IL-10 in the human hepatoma cell line Huh7 co-cultured with peripheral blood mononucleated cells (PBMCs) of healthy volunteers were measured. The correlations between p-STAT3 and IFN-γ/IL-4, IFN-γ, IL-4, IL-6 and IL-10 were then analyzed. Results showed that the p-STAT3 level is higher in CD4+ and CD8+ T cells in the peripheral blood of HCC patients, and in PBMCs co-cultured with Huh7 cells compared to controls. The cytokine (IL-4, IL-6 and IL-10) levels were increased and the IFN-γ level was decreased in the serum of HCC patients and in supernatants of PBMCs co-cultured with Huh7 cells. Correlation analyses demonstrated that the IFN-γ/IL-4 ratio and the IFN-γ level negatively correlate to the p-STAT3 level in CD4+ and CD8+ T cells in samples from patients and in cells cultured in vitro. By contrast, the levels of IL-4, IL-6 and IL-10 positively correlated to the p-STAT3 level. This study indicated that the expression of p-STAT3 is upregulated in peripheral CD4+ and CD8+ T cells of HCC patients, and which may result in abnormal immune surveillance and thereby, contribute to HCC pathogenesis.

Abstract
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease characterized by excessive production of a variety of autoantibodies, accumulation of immune complexes, and multiple organ systems involvement. Interleukin-10 (IL-10) has an important role in the growth, survival, differentiation, and function of B cells. Abnormally increased IL-10 synthesis seems contributing to the spontaneous hyperactivity of the B cell compartment, so that it can directly result in autoantibody production by committed plasma cells, circulating immune complexes formation, and eventually in tissue and organ damage, suggesting it might associate with the development of SLE. A better understanding of the regulation of IL-10 and its receptors (IL-10R) can likely provide more valuable clues to the pathogenic mechanisms underlying specific forms of SLE, so as to pave the way toward more effective therapeutics.

Abstract
Results from patients with systemic lupus erythematosus (SLE) and from mice suffering from a lupus-like disease suggest that the IL-10 pathway is involved in pathogenesis, and that this cytokine could represent a target for managing SLE development. In this study, we constructed JC virus-like particles (VLP) expressing IL-10-specific short hairpin RNAs (shRNAs) that efficiently silenced IL-10 gene expression. In mice, a single injection of this preparation dramatically reduced serum levels of ILIO. We tested the preventive effect of this vector expressing anti-IL-10 shRNAs in female (NZBxNZW) F, mice. Weekly intraperitoneal injections decreased the incidence and severity of proteinuria, and prolonged lifespan, with reduced IL-10 production. Our data demonstrate that the IL-10 pathway plays a chief role in lupus pathogenesis. It indicates that JC virus-like particles represent a potent vector for delivering interfering RNA in vivo. They suggest that RNA interference targeting IL-10 is an effective strategy to silence the IL-10 pathway, and possesses a therapeutic potential that could be useful in the management of SLE and, possibly, other immune-mediated disorders.

Adenovirus-mediated dual gene expression of human interleukin-10 and hepatic growth factor exerts protective effect against CCl4-induced hepatocyte injury in rats. Dig Dis Sci 2012; 57:1857-65. [PMID: 22399249 DOI: 10.1007/s10620-012-2117-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2011] [Accepted: 02/22/2012] [Indexed: 12/27/2022]
Abstract
BACKGROUND Hepatocyte injury is a common pathological cause of various liver diseases. Due to a lack of an effective preventive treatment, gene therapy has become an interesting approach to prevent and alleviate liver injury. AIMS A protective effect of adenovirus-mediated dual gene expression of human interleukin-10 (hIL-10) and human hepatocyte growth factor (hHGF) was investigated against tetrachloromethane (CCl(4))-induced hepatocyte injury in rats. METHODS An adenoviral vector carrying the hIL-10 and hHGF genes was constructed, and its protective effect against rat hepatocyte injury was investigated both in vivo and in vitro. RESULTS In the in vitro CCl(4)-induced cell injury model, simultaneous transfection of hIL-10 and hHGF genes via an adenoviral vector resulted in production of anti-hepatocyte biological factors by an autocrine mechanism, then significantly improved hepatocyte viability. In the in vivo rat model, synergistic effects of these two gene products protected hepatocytes from damage by reducing the CC1(4)-induced hepatocyte degeneration, hepatic fibrosis, and intrahepatic inflammatory cell infiltration, thereby preserving liver function. CONCLUSION Adenovirus-mediated dual gene expression of hIL-10 and hHGF effectively protected against liver damage by likely regulating immune responses to reduce hepatocyte injury and by promoting hepatocyte regeneration. The hIL-10 and hHGF dual gene expression vector has significant potential in the field of liver disease therapeutics and constitutes one of the most promising current strategies for gene therapy.

Abstract
OBJECTIVE Studies have suggested that interleukin-10 receptor1 (IL-10R1) is involved in genetic susceptibility to systemic lupus erythematosus (SLE) in animal models and Caucasians. Therefore, the current study was designed to determine whether the IL-10R1 gene plays a role in the pathogenesis of human SLE in the Chinese Han population. METHODS The seven exons of the IL-10R1 gene were amplified and sequenced using a BigDye Terminator v1.1 Cycle Sequencing kit and an ABI 3100 DNA Analyzer. A missense single nucleotide polymorphism (SNP) locus with a minor allele frequency of at least 0.1 was chosen to evaluate the correlation with the incidence of SLE. RESULTS Seven SNPs were found to reside in the exons of the IL-10R1 gene. Among the SNPs, A744G was evaluated for a correlation with the incidence of SLE because A744G was the only missense SNP with a minor allele frequency of at least 0.1. There was no significant difference in the distribution of the A and G alleles between the SLE patient group and the healthy control group (P = 0.693). Furthermore, the genotype frequencies of A744A, A744G and G744G did not differ significantly between the two groups (P = 0.906). CONCLUSION In the Chinese Han population, missense SNPs within the exons of the IL-10R1 gene do not contribute to the development of SLE.
