به طور معمول مازاد تغذیه، در بدن به صورت چربی ذخیره و به چاقی منجر می شود. یکی از عوامل ابتلا به دیابت نوع 2 ، چاقی است. tlr به عنوان یک پیوند ملکولی بین اسید های چرب آزاد ، التهاب و سیستم ایمنی عمل می کنند. tlr از طریق تولید سایتوکاین های پایین دست از قبیل il-10, il-6 ،il-1? ، tnf-? منجر به بروز التهاب می شوند. این سایتوکاین ها در پاسخ به محرک التهابی ترشح می شوند و مسیر های سیگنالینگ التهاب...
Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...
background: early childhood caries (ecc) is a common health problem in the developing countries. basic knowledge about the etiology and pathogenesis of ecc plays an important role in its prevention. objective: to determine the relationship between salivary tlr-2 concentration and early childhood caries formation methods: twenty-eight children with ages ranging from 36 to 71 months (15 in ecc gr...
Here, we have investigated the mRNA expression of Toll-like receptor 2 (TLR-2), TLR-4, and MD-2 in spleens and livers of C3H/HeN mice (carrying wild-type TLR-4) and C3H/HeJ mice (carrying mutated TLR-4) in response to Salmonella infection. During Salmonella infections, TLR-4 is activated, leading to increased TLR-2 and decreased TLR-4 expression.
مقدمه: در عفونتهای پریودنتال پیش نیاز شروع پاسخهای میزبان، شناخت پاتوژنها توسط سیستم ایمنی میزبان میباشد. خانواده رسپتورهای toll-like (tlrs)، مسئول شناسایی ساختارهای حفظ شده میکروبیال نظیر لیپوپلی ساکارید (lps) باکتریها میباشند و مسیرهای سیگنال دهنده را که در نهایت منجر به پاسخهای ایمنی میشود، فعال میکنند. هدف از مطالعه حاضر، ارزیابی مقایسه میزان بروز tlr-2 و tlr-4 توسط تکنیک real-...
INTRODUCTION Toll-like receptors (TLRs) are an important link between innate and adaptive immunity. MATERIAL AND METHODS Expression of TLR-2, TLR-4, and TLR-9 genes was assessed in 60 coronary artery disease (CAD) patients and 79 controls by SYBR Green 1 based real time PCR assay. RESULTS Expression of the TLR-2 gene was found to be significantly elevated in cases (1.295 ±0.09) compared to ...
A missense mutation in the cytoplasmic domain of the Toll-like receptor-4 (TLR-4) has been identified as the defect responsible for lipopolysaccharide (LPS) hyporesponsiveness in C3H/HeJ mice. TLR-4 and TLR-2 have recently been implicated in LPS signaling in studies where these receptors were overexpressed in LPS non-responsive 293 human embryonic kidney cells. However, the signaling role of TL...
Objective(s): TLR-4 activates a number of inflammatory signaling pathways. Also, AMPK could be involved in anti-inflammatory signaling. The aim of this study was to identify whether stimulation of AMPK could inhibit LPS-induced Tlr-4 gene expression in mice hearts. Materials and methods: Heart AMPK activity and/or Tlr-4 expression was stimulated in different mice groups, using respectively IP i...
BACKGROUND The incidence of ischemic reperfusion injury (IRI) in early phase post-transplantation and activation of toll-like receptor (TLR-2) and TLR-4 remarkably impact the outcome of a renal allograft. OBJECTIVE To investigate whether the expression of TLRs in peripheral blood mononuclear cells (PBMCs) can predict the clinical outcome of kidney allografts. METHODS We obtained blood sampl...
