Toll-like receptor 4 is a part of the innate immune system and recognizes Helicobacter pylori lipopolysaccharide. The goal of this study was to analyze the role of Toll-like receptor 4 polymorphisms +896 (rs4986790) and +1196 (rs4986791) in the pathogenesis of Helicobacter pylori related gastroduodenal diseases in relation to gastric secretion and inflammation. Toll-like receptor 4 polymorphism...
Toll-like receptor (TLR) signaling has been implicated in the inflammatory responses in intestinal epithelial cells (IECs). Such inflammatory signals mediate complex interactions between commensal bacteria and TLRs and are required for IEC proliferation, immune response, repair, and homeostasis. The upregulation of certain TLRs in colorectal cancer (CRC) tissues suggests that TLRs may play an e...
The Toll-like receptor family mediates the innate immune system through recognizing the molecular patterns of microorganisms and self-components and leading the synthesis of the inflammatory mediators. We retrospectively examined whether or not genetic variations in toll-like receptor 1 (rs5743551, -7202GQ>A), toll-like receptor 2 (rs7656411, 22215G>T), and toll-like receptor 4 (rs11536889, +37...
استرس حالتی است در روان و تن که ناشی از وارد شدن فشارهای روحی و جسمی به فرد است. استرس مزمن باعث بیماری هایی مانند افسردگی و اضطراب می شود. امروزه از مهمتر?ن بحثهای مطرح در جوامع پزشک? و بو?ژه در کشور ما اهم?ت و نقش گ?اهان دارو?? و سنت? در درمان ب?ماری ها م?باشد. گیاه مرزنجوش با اسم علمی origanum vulgare از تیره lamiaceae پراکنش وسیع جهانی دارد و از گیاهان خوراکی رایجی است که در نقاط مختلف دنیا...
signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...
background: toll like receptors (tlrs) are well recognized players in inflammatory conditions. among them tlr-4 is involved in chronic inflammatory processes such as formation of atherosclerotic plaques. objective: the present study was aimed to examine the effects of percutanoeus coronary intervention (pci) as a revascularization method on monocyte expression of htlr-4 and on the serum levels ...
background: multiple sclerosis (ms) is a t cell mediated autoimmune disease with unknown etiology. appropriate ms therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. ligation of tlr-2 and tlr-4 stimulates the production of several cytokines leading to cns autoimmunity and neurodegenerative diseases. objective: to find a relationship between m...
BACKGROUND Mechanical ventilation induces diaphragm muscle atrophy, which plays a key role in difficult weaning from mechanical ventilation. The signaling pathways involved in ventilator-induced diaphragm atrophy are poorly understood. The current study investigated the role of Toll-like receptor 4 signaling in the development of ventilator-induced diaphragm atrophy. METHODS Unventilated anim...
طبق مطالعات مختلف، مرفین دارای اثرات تعدیل کننده ایمنی می باشد. اما مکانیسم های دقیق این اثرات در cns تا حد زیادی ناشناخته است. در این مطالعه، پتانسیل بالقوه پیش تیمار مرفین در التهاب عصبی القاء شده با لیپوپلی ساکارید (lps) بررسی شد. بدین منظور، اثر سه دوز مرفین )10 و 7و 4 mg/kg) روی بیان سیتوکین های پیش التهابی tnf?,il-i? و cox-2 در هیپوکمپ rat، همچنین احتمال درگیری رسپتورهای اوپیوییدی mor و...
