بروز لیشمانیوز جلدی که در پی انتقال لیشمانیا ماژور به پوست توسط پشه ناقل صورت می گیرد، متاثر از عملکرد همکارانه سلولهای t تنظیمی cd25+foxp3+ ساکن پوست است. بلافاصله پس از ورود لیشمانیا به پوست، لیشمانیا توسط ماکروفاژها و سلولهای دندریتیک به دام میافتند و مانع القای پاسخهای ایمنی نوع یک توسط این سلولها می شوند. یکی از مکانیسمهای مهاری لیشمانیا ، می تواند القای سلولهای t تنظیمی توسط ماکروفاژها با...
Abstract The impact of using chemical fertilizers in the cultivation system changes soil’s physicochemical characteristics. Local resources-based amelioration technology can be used as a solution to increase soil fertility and plant productivity. This study aimed measure properties Inceptisols monoculture polyculture systems. A randomized block design was this research with eight treatments thr...
Abstract: Background and Aim: The increasing incidence of infertility is alarming. About 10-30% of infertility are classified as Unexplained Infertility (UI) which is not an absolute clinical condition. TGF-b1 is multifunctional cytokine and produced mainly by T regulatory (Treg) lymphocytes. This cytokine plays important roles in physiology of normal pregnancy. The association of Single...
Objective(s): To investigate and test the hypotheses that TGF-β1 enhanced myocardial differentiation through Wnt/β-catenin pathway with rat bone marrow mesenchymal stem cells (BMSCs).Materials and Methods: Lentiviral vectors carrying the TGF-β1 gene were transduced into rat BMSCs firstly. Then several kinds of experimental methods were u...
Abstract Introduction High-grade primary brain tumors cause serious morbidity and mortality. This study aimed to investigate the role of transforming growth factor beta (TGF-β) suppressor mothers against decapentaplegic (Smad) receptors in high-grade tumors. Material Method Thirteen patients with a pathological diagnosis glioblastoma multiforme were included study. Pathological preparations eac...
Background and Aims: TGF-β is an effective cytokine in the viral replication cycle, which is also highly relevant to the pathogenesis of some viral infections. TGF-β induction by viral proteins is one of the ways to escape the virus from the immune system by inhibiting interferon signaling and other immune system factors. In recent years, the role of TGF-β and its inhibitor...
Transforming growth factor beta (TGF-b) is a mediator released by nearly all cell types. It has suppression activity on the immune system, but exactly how this effect is carried out is not clear. Previous experiments showed that IgG interacts with or carriers active TGF-b, that could suppresses cytotoxic T-cell responses to an immunogenic tumor in mice. Since T cell receptor (TCR) has structura...
Objective(s): Transforming growth factor alpha (TGF-α) has been shown to modulate the gastric acid secretion. Therefore, the aim of the present study was to investigate the effect of sodium hydrosulfide (NaHS) on TGF-α expression in gastric mucosa in rats. Materials and Methods: Eighteen rats were randomly divided into 3 groups (6 per group). To determine the effect of NaHS on gene and protein ...
Background: Normal tissue toxicity continues to remain as a major challenge for radiation oncologists for delivering the total dose to the tumour cells in cancer patients. Cellular, molecular and plasma based early biomarkers to predict the overreactions and non-overreactions of normal tissue toxicity before the initiation of radiotherapy can be valuable for personalised treatment. The aim of t...
زمینه و هدف: سولفور موستارد یک عامل تاول زا می باشد که در طی جنگ ایران و عراق به عنوان سلاح جنگی مورد استفاده قرار گرفته است. یکی از مهمترین بافت های درگیر در صدمات ناشی از گاز خردل ریه می باشد. تغییر در ساختار مورفولوژیکی راه های هوایی و فیبروز اطراف برونشیول ها به دنبال استنشاق گاز خردل در جانبازان شیمیایی با عارضه مزمن انسدادی راه های هوایی (COPD) دیده می شود.یکی از مولکول هایی که در ایجاد ف...
