BACKGROUND Although (192)Ir intracoronary brachytherapy has been demonstrated to dramatically reduce the recurrence of in-stent restenosis, up to 24% of these patients will still require repeat target-vessel revascularization. The short- and long-term outcomes of repeat percutaneous intervention in this population have not been characterized. METHODS AND RESULTS Analysis was performed of all ...
a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...
TLR2-dependent cellular signaling in Mycobacterium tuberculosis-infected macrophages causes apoptosis and inhibits class II major histocompatibility complex (MHC-II) molecules antigen processing, leading to evasion of surveillance. Mycobacterium tuberculosis (MTB) lipoproteins are an important class of Toll-like receptor (TLR) ligand, and identified as specific components that mediate these eff...
background one-third of the world’s population is infected with mycobacterium tuberculosis. investigation of toll-like receptors (tlrs) has revealed new information regarding the immunopathogenesis of this disease. toll-like receptors can recognize various ligands with a lipoprotein structure in the bacilli. toll-like receptor 2 and tlr-4 have been identified in association with tuberculosis in...
Although triglyceride accumulation in the liver causes non-alcoholic fatty liver disease (NAFLD), hypercholesterolemia is also a main cause of NAFLD as well as atherosclerosis. However, NAFLD and atherosclerosis have not been investigated simultaneously in animal models fed a high-cholesterol diet. Moreover, it is unclear whether systemic inflammation can exacerbate both pathologies in the same...
پاتوژن های مهاجم توسط دستگاه ایمنی ذاتی و اکتسابی کنترل می شوند. دستگاه تولید مثل ماده از نظر ایمنولوژیک در قدرت خود برای القاء بی پاسخی نسبت به فلور طبیعی میکروبی در بخش های پایین تر این دستگاه و پاسخ به باکتری های پاتوژن منحصر به فرد است. به طوری که بخش های بالاتر دستگاه تولید مثل ماده شامل: بدنه ی رحم، شاخ رحم و لوله های رحمی عملا? فاقد ارگانیسم ها هستند. باکتری های خودی بدون القاء پاسخ الته...
TLR signaling is critical for early host defense against pathogens, but the contributions of mast cell TLR-mediated mechanisms and subsequent effector functions during pulmonary infection are largely unknown. We have previously demonstrated that mast cells, through the production of IL-4, effectively control Francisella tularensis replication. In this study, the highly human virulent strain of ...
TLR ligands induce dendritic cell (DC) maturation. During this process, cells initiate proteolytic degradation of internalized protein Ags into peptides that complex with MHC class II (MHC II) and simultaneously increase expression of costimulatory molecules and of cytokines such as IL-6, IL-12, and IL-23. In these ways, TLR-activated DCs are able to activate naive Th cells and initiate Th1 and...
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 مطالعة حاضر، ارزیابی مقایسه میزان بروز TLR-2 و TLR-4 توسط تکنیک Real-...
Background: Toll-like receptors (TLRs) detect diverse pathogen-associated molecular patterns and play a critical role in the innate immune response. Hosts should activate TLR-signaling pathways to eliminate invading pathogens. However, excessive activation of these pathways may interrupt immune homeostasis, leading to several diseases. Therefore precise regulation of TLR-signaling pathways is e...
