Background: TGF-β has long been considered as the main inducer of Tregs in tumor microenvironment and is the reason for the aberrant number of Tregs in tumor-bearing individuals. Recently, it has been suggested that the enzyme arginase I is able to mediate the induction of Tregs in a TGF-β-independent fashion. The recombinant WW2/WW3 domains from smad ubiquitination regulatory factor 2 molecule...
the purpose of this study was to determine the role of streptococcal m protein in naturally-occurring cd4+cd25+ regulatory t cells (ntregs) function and development in rheumatic heart disease in iraqi patients. streptococcus pyogenes was isolated for subsequent m protein extraction. also, peripheral blood ntregs and cd4+ t cells were isolated by using magnetic cell separation system. tissue cul...
سابقه و هدف: امروزه اطلاع دقیقی از وضعیت پریودنتال مبتلایان به ویروس hiv با ضعف سیستم ایمنی مستعد ابتلا به بیماری های پریودنتال و ضایعات فرصت طلب دهانی در دست نیست. تحقیق حاضر با هدف تعیین وضعیت پریودنتال افراد مبتلا به hiv مراجعه کننده به بخش عفونی و مرکز مشاوره بیماری های رفتاری امام خمینی و مرکز کاهش خسارات پرسپولیس در فاصله سال های 84-1383 انجام گرفت.مواد و روشها: تحقیق توصیفی حاضر بر روی 1...

idiopathic cd4+ lymphocytopenia is a rare combined immunodeficiency disease, characterized by low cd4+ t-cell count and increased susceptibility to opportunistic infections, autoimmunity and malignancies after exclusion of secondary forms of cd4 lymphocytopenia. here we present a 13-year old boy who was referred to our center because of destructive ulceration of soft and hard palates with exten...
سابقه و هدف: با توجه به روند رو به افزایش شیوع hiv و اهمیت مطالعات اپیدمیولوژی آن، هدف از این مطالعه بررسی اسمیر سرویکس در افراد مبتلا به عفونت hiv و همچنین ارتباط سطح cd4 با اسمیر غیرطبیعی سرویکس در میان یک جمعیت ایرانی بوده است. مواد و روشها: 247 زن در یک مطالعه مورد شاهدی (58 بیمار hiv مثبت ثبت شده در مراکز بهداشتی شمال و شرق تهران و 189 فرد سالم) وارد مطالعه شدند. سیتولوژی سرویکس که به صورت...
Introduction: Intense exercise leads to a decrease in immune system. The aim of this study was to investigate the effect of short-term garlic extract supplementation on some cellular immune system factors after intense exercise in karate athletes. Methods: Eighteen young men (with a mean age of 20.07±4.46, BMI 22.72±2.99 kg/m2) volunteered to participate in this semi-experimented...
Background: Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which T-cell mediated selective pancreatic β- cell destruction occurs. Half the risk of T1DM development is given by the HLA gene region while the remaining risk is assigned to non-HLA genes , probably those engaged in the formation of antigen interaction complex. The CD4 gene product, which is among the most prominent T-ce...
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...
Background: Drugs used in cancer treatment specifically kill T regulatory cells. Objective: To determine different phenotypes of T regulatory cells during the maintenance phase chemotherapy for pediatric acute lymphoblastic leukemia (ALL). Materials: We evaluated the percentages of regulatory T cells by flow cytometry. Soluble CTLA-4 (sCTLA-4) ...
