Myasthenia gravis (MG) is an autoimmune disease mediated by auto-antibodies against the neuromuscular junction. The thymus has an important role in the pathogenesis of MG because most of the patients have thymic pathology and thymectomy (TE) can reduce the severity of the disease. In the present study, the frequency of Th17 and Tc17 cells were studied in MG patients (pre and 6 months post-TE) a...

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 counterb...

Background : Allergic asthma is a chronic inflammatory disease of airway that often determined with degrees of inflammation, hypersensitivity, bronchial constriction and airway changes. Th1, Th2 and Th17 cells are the main cells involved in the pathophysiology of asthma. . Therefore, this study evaluated Th1, Th2, and Th17 cells functions by assessment the expression of INF-g, IL-4, and IL-17 g...

objective(s): this study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by th17/treg. materials and methods: experimental periodontitis was established by silk thread ligation with porphyromonasgingivalis daubing in the bilateral maxillary second molar of male sprague-dawley (sd) rats. alveolar bones were scanned by micro...

Background: Recurrent miscarriage (RM) affects 2-5% of pregnant women. Paternal lymphocyte immunotherapy is a common treatment for RM patients but the outcome has not been consistent. Therefore, combined therapy with other immunosuppressive drugs such as 1 a, 25-dihydroxy-vitamin-D3 (vitamin D3) may improve the outcome. Objectives: To investigate the effect of vitamin D3 on the balance of two...

primary sjögren's syndrome (pss) is a common autoimmune disease involving abnormal th17 activation. the aim of the current study was to investigate the immunosuppression effect of cyclosporine a (cys a), a potent immunosuppressor on the proliferation and activation of t cells, on the activation of th17 cells. blood samples from both inactive and active pss patients as well as healthy controls w...

t lymphocytes that are involved in cellular mediated immunity include two types known as tcd8+ (cytotoxic t lymphocytes) and tcd4+ (helper t lymphocytes). tcd4+ has four main subtypes, including th1, th2, th17, and treg lymphocytes.th17 lymphocytes play a role in defense against microbes that th1 and th2 lymphocytes have not the ability to respond to them. the most important cytokines, which ar...

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by T-cells imbalance. There are ongoing controversies about the role of specific T-helper cell subsets and their cytokines. The study aimed to confirm the disturbance of Th17/Treg ratio in SLE patients. Methods: Subjects were SLE patients who met the American College of Rheumatology 1997 criteria. Dis...
