background: lack of sufficient information on the mechanism of plasma exchange (pe) therapy in multiple sclerosis (ms), has limited this treatment to individual patients with severe relapses who have been refractory to other treatments. this is while pe is used very successfully as a first-line standard treatment in many other neuro-immune disorders. recent data suggest that treg/th17 counterba...
Abstract Background Primary biliary cholangitis (PBC), an autoimmune liver disease, presents with progressive damage to the intrahepatic bile ducts infiltrating mononuclear cells and appearance of anti‐mitochondrial antibodies (AMAs). The initiation disease is permissively mediated by dysfunctional regulatory T (Treg cells). Naïve CD4 + cultured splenic B220 without additional cytokines or chem...
Abstract The transcription factor TCF-1 is essential for the development and function of T regulatory (Treg) cells, however its poorly understood. Here, we show that primarily suppresses genes are co-bound by Foxp3. Single-cell RNA-seq analysis identified effector- central-memory Treg-cells with differential expression Klf2 memory activation markers. deficiency did not change core Treg transcri...
Gut commensal microbes affect the mucosal immune system via expansion of regulatory T cells (Treg) in colon. This is mediated short-chain fatty acids (SCFA), bacterial metabolites generated during fiber fermentation. SCFA are also produced by skin bacteria and may activate resident Treg, activity which diminished certain inflammatory dermatoses. Only upon binding to G-protein coupled receptors,...
Foxp3+ T regulatory (Treg) cells suppress immune cell activation and establish normal immune homeostasis. How Treg cells maintain their identity is not completely understood. Here we show that Ndfip1, a coactivator of Nedd4-family E3 ubiquitin ligases, is required for Treg cell stability and function. Ndfip1 deletion in Treg cells results in autoinflammatory disease. Ndfip1-deficient Treg cells...
Foxp3+ regulatory T (Treg) cells are broadly divided into naive-like and activated Treg cells, however recent studies suggest further Treg cell heterogeneity. Treg cells contribute to impaired T cell responses in chronic infections, but the role of specific Treg cell subpopulations in viral infections is not well defined. Here, we report that activated Treg cells are separated into two transcri...
helicobacter pylori (h. pylori) is a gram-negative bacterium that colonizes the human stomach and affects more than half of the global human population. this microorganism shows variations in its geographical distribution and causes chronic gastritis, peptic ulcer, gastric adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. the development of these clinical entities depends on the ba...
PURPOSE Regulatory T (Treg) cells are key modulators in the immune system. Recent studies have shown that atopic dermatitis (AD) patients have higher numbers of Treg cells; however, little is known about the specific phenotype and function of Treg cells in AD. MATERIALS AND METHODS To identify differentially expressed proteins in peripheral induced Treg cells in AD and naturally derived Treg ...
patients and methods in this cross-sectional study, peripheral mononuclear cells (pbmcs) were isolated from peripheral blood of 29 patients with newly diagnosed pulmonary tb and 19 patients with positive tuberculin skin test. the pbmcs were activated with ppd for 72 hours. activated cells were harvested, rna was extracted and cdna was synthesized. a real-time taqman method was designed and opti...
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...
