Background: TGF-β isoforms play crucial roles in diverse cellular processes. Therefore, targeting and inhibiting TGF-β signaling pathway provides a potential therapeutic opportunity. TGF-β isoforms bind and bring the receptors (TβRII and TβRI) together to form a signaling complex in an ordered manner. Objectives: Herein, an antagonistic variant of TGF-β (AnTβ)...
background: cutaneous leishmaniasis is a neglected parasitic disease, which imposes massive human distress and financial costs to the endemic countries. better understanding of host immune response to the parasite leads to helpful strategies for disease control. interleukin (il)-10 and transforming growth factor (tgf)-β are important immune regulatory cytokines, which appear to develop non-heal...
Background: Successful pregnancy in allopregnant women depends upon the control of graft rejection mechanisms. It has been suggested that some immunosuppressive cytokines contribute to successful pregnancy and transplantation. Transforming growth factor beta (TGF- β) exhibits potent immunoregulatory and anti-inflammatory properties which might prolong graft survival. Recent studies suggest a ...
سیستمیک اسکلروزیس نوعی بیماری بافت پیوندی است که معمولا پوست و در موارد پیشرفته آن ریه، کلیه و قلب را نیز درگیر مینماید. اتیولوژی و پاتولوژی این بیماری ناشناخته است. یک عامل موثر از قبیل ویروس یا مواد شیمیایی برای افرادی که از نظر ژنتیکی مستعد ابتلا به سیستمیک اسکلروزیس باشند، می تواند سرآغاز ایجاد بیماری باشد. از مکانیسم های احتمالی درگیر در پاتولوژی این بیماری آسیب به رگ های خونی کوچک، رسوب ک...
چند قلوزایی یکی از مهمترین صفات اقتصادی در پرورش بز است، که علاوه بر تأثیر پذیری از ژن های کوچک اثر، تحت تأثیر ژن های با اثر بزرگ نیز می باشد. در دهه های اخیر مشخص شد که دو عضو متعلق به خانواده فاکتورهای رشد با منشأ اووسیتی به نامهایgdf9 وbmp15 برای رشد فولیکولی و تخمک ریزی ضروری هستند. هدف از پژوهش حاضر مطلعهی چند شکلی در جایگاههای ژنی gdf9 وbmp15 و ارتباط الگوهای ژنوتیپی شناسایی شده در...
Background: Ageing and physical inactivity can negatively affect immune system. On the contrary, a healthy lifestyle and physical activity can improve immune system and prevent from mild inflammatory diseases. Transforming Growth Factor-β (TGF-β) can play an important role in the regulation of immune function and inflammation. This study aimed to investigate the effects of 8 weeks of theraband ...
the widespread use of sulfur mustard (sm) as a chemical warfare agent in the past century has proved its long-lasting toxic effects. despite a lot of research over the past decades on iranian veterans, there are still major gaps in the sm literature. transforming growth factor (tgf-β), a cytokine that affects many different cell processes, has an important role in the lungs of pati...
background: regulatory cd4+t (treg) cells are effective in maintaining immune tolerance. objective: to investigate single nucleotide polymorphisms (snps) of transforming growth factor β-1 (tgf-β1) and forkhead box protein 3 (foxp3) genes in iranian patients with allergic rhinitis (ar). methods: variations at codons 10 and 25 of tgf-β1 and foxp3 at positions -3279 a>c and -924 a>g were evaluated...
The aim of this study to evaluate the expression Programmed cell death-1 (PD-1), TGF- ß, and IL-10 in placental tissue aborted women correlation with Toxoplasma.gondii (T. gondii) these cytokines each other toxoplasmosis, during an abortion. samples have been processed used for immunohistochemistry PDL-1, IL-10, TGF-β. There was increase TGF-β, infected T.gondii, results showed that residence p...
transforming growth factor-beta (tgf-β) is one of the most important cytokines implicated in growth, differentiation, repair and also the pathogenesis of the lung fibrosis by its stimulatory effect on extracellular matrix deposition. pulmonary epithelial cells are considered as a source of tgf-β in lung. substance p (sp), as a neuroimmunomodulator has elevated levels in inflamed airways and alt...
