The T helper 17 (Th17) cells represent a subset of CD4+ T-cells with unique effector functions, developmental plasticity, and stem-cell features. Th17 cells bridge innate and adaptive immunity against fungal and bacterial infections at skin and mucosal barrier surfaces. Although Th17 cells have been extensively studied in the context of autoimmunity, their role in various other pathologies is u...
BACKGROUND Immunosuppression and age-related deficiencies in cell-mediated immunity are important factors for the reactivation of latent varicella-zoster virus (VZV). CD4+CD25+Foxp3+ regulatory T (Treg) cells and T helper 17 (Th17) cells are closely associated with various viral infections. OBJECTIVE We analyzed Treg cells and Th17 cells in patients with herpes zoster and investigated their r...
The development of Th17 cells is accompanied by the acquisition of responsiveness to both IL-12 and IL-23, cytokines with established roles in the development and/or function of Th1 and Th17 cells, respectively. IL-12 signaling promotes antigen-dependent Th1 differentiation but, in combination with IL-18, allows the antigen-independent perpetuation of Th1 responses. On the other hand, while IL-...
Objective(s): Multiple sclerosis (MS) is considered as a chronic type of an inflammatory disease characterized by loss of myelin of CNS.Recent evidence indicates that Interleukin 17 (IL-17)-producing T helper cells (Th17 cells) population are increased and regulatory T cells (Treg cells) are decreased in MS. Despite extensive research in understanding the mechanism of Th17 and Treg differentiat...
چکید ه سابقه و هدف یکی از اساسیترین سلولهای سیستم ایمنی که در بیماری مولتیپل اسکلروزیس( MS ) دخالت دارد، سلول Th17 میباشد که در بسیاری دیگر از بیماریهای خود ایمن نیز اثرگذار است. اخیراً از میکرو RNA ها در درمان بسیاری از بیماریها استفاده میشود. miRNA ها دستهای از RNA های غیر کد شونده به طول 22 تا 25 نوکلئوتید هستند که نقشهای تنظیمی اساسی در فرآیندهای مختلف سلولی دارند. در این مطالع...
IL-17A-expressing CD4(+) T cells (Th17 cells) are generally regarded as key effectors of autoimmune inflammation. However, not all Th17 cells are pro-inflammatory. Pathogenic Th17 cells that induce autoimmunity in mice are distinguished from nonpathogenic Th17 cells by a unique transcriptional signature, including high Il23r expression, and these cells require Il23r for their inflammatory funct...
Objective(s): Th2 response is related to the aetiology of asthma, but the underlying mechanism is unclear. To address this point, the effect of nebulized inhalation of inactivated Mycobacterium phlei on modulation of asthmatic airway inflammation was investigated. Materials and Methods: 24 male BALB/c mice were randomly divided into three groups: control group (Group A), asthma model group (G...
CD4+ T-helper cells producing interleukin-17 (IL-17), known as T-helper 17 (TH17) cells, comprise heterogeneous subsets that exhibit distinct pathogenicity. Although pathogenic and non-pathogenic TH17 subsets share a common RORγt-dependent TH17 transcriptional programme, transcriptional regulatory mechanisms specific to each of these subsets are mostly unknown. Here we show that the AP-1 transc...
background: systemic lupus erythematosus (sle) is a multisystem autoimmune disease. emerging data suggests that t helper 17 (th17) cells play a pathogenic role in sle and the increased number of these cells correlates with disease activity. in recent years, 1α, 25-dihydroxyvitamin d3 (1,25vitd3) has been considered as an immunomodulatory factor. objective: to investigate the effect of 1,25vitd3...
Helper T cells producing IL-17 (Th17) have high plasticity: restimulation of lymphocytes in an inflammatory environment can induce their transformation into with another phenotype, and a shift towards Th1 is the most common. The result this appearance expressing along classical markers Th17 key Th1-associated molecules. In its general form, population represented by CD4 + CD161 CCR6 CXCR3 IFNγ ...
