مقایسه تعداد مطلق جمعیت لنفوسیت هایT CD4+CD25+ خون محیطی در زنان با سقط جنین مکرر و حاملگی های طبیعی
Introduction: Undoubtedly, reproduction is a necessity for survival and successful pregnancy is an immunological paradox. In the present study, we investigated the proportional changes of CD4+CD25bright T cells, CD4+CD25dim T cells in peripheral blood in unexplained recurrent spontaneous abortions (URSA) and compared it with normal pregnant women by antibody monoclonal method. Methods: The st...
Behcet disease (BD) is a systemic inflammatory disease of the unknown etiology. There is however, some evidence to suggest that immunological abnormalities are important in its pathogenesis, furthermore several T-cell abnormalities which may be quite relevant to autoimmune origin of the disease have been described. We report here our study of T-cell subsets, B and NK cells in 68 patients with B...
Celiac disease (CD) is a systemic immune-mediated disorder caused by the dietary gluten in individuals who are genetically susceptible to the disease. In fact, CD is a T cell-mediated immune disease in which gluten-derived peptides activate the lamina propria CD4+ Teff cells, and these T-cell subsets can cause the intestinal tissue damages. Also, there are additional subsets of CD4+ T cells wit...
cytokine production in response to allergens may influence the development of atopy- predisposing immune responses, initializing the early programming of allergy and asthma. vitamin d intake may be protective due to its immunoregulatory properties, that may contribute to influence the expression of the atopic phenotype initiated in early life. the objective of our study was to ...
Background: Programmed cell death protein-1 (PD-1)/PD-L1 pathway is one of the immune checkpoint pathways involved in regulation of the immune responses and suppression of anti-tumor defense. PD-1/B7-H1-blocking antibodies improve immune responses such as cytotoxic activity of CD8+/CD4+T cells and also increase mortality of tumor cells; however their use is accompanied by adverse effects in pat...
Background: Polycystic ovary syndrome (PCOS) is considered as the most common cause of female infertility that affects 4-10% of women in the reproductive age. Previous studies have shown the role of a balanced immune response in a successful pregnancy and fertility. Objective: To investigate the T helper cells type 1 (Th1) /Th2/Th17/Treg paradigms in peripheral blood of infertile PCOS compared ...
High level of CMV-specific CD4+ and CD8+cells Immune Response and Correlation Between them in B-cell Chronic Lymphocytic Leukemia Patients B. Pourgheysri [1] , P. Moss [2] Received: 10/09/07 Sent for Revision: 05/03/08 Received Revised Manuscript: 06/12/08 Accepted: 30/12/08 Background and Objective: Chronic lymphocytic leukemia (CLL) is characterized by a monoclonal proliferation o...
in this paper, the multistage variational iteration method is implemented to solve a general form of the system of first-order differential equations. the convergence of the proposed method is given. to illustrate the proposed method, it is applied to a model for hiv infection of cd4+ t cells and the numerical results are compared with those of a recently proposed method.
Introduction & Objective: Both CD4+ type 1 helper (Th1) cells and CD8+ T cells play effective roles in protection against Mycobacterium tuberculosis infection. DNA vaccine encoding MPB51 can induce Th1-type immune responses and protective immunity upon challenge with M.tuberculosis. This study address to identify T-cell immunodominant epitopes on MPB51 in C57BL/6 mice. Materials & Methods : ...
Background: Type 1 diabetes (T1D) is a T cell mediated autoimmune disease targeting the insulin-producing β cells within pancreatic islets. Autoimmune diseases may develop as a consequence of altered balance between regulatory (Tregs) and autoreactive T cells. Objectives: To evaluate Treg cells frequency and suppressive function in the peripheral blood of newly diagnosed T1D patients in compari...
