Accumulating evidence indicates that toll-like receptor 4 (TLR4) plays a critical role in promoting adaptive immune responses and are definitively involved in the expansion and maintenance of the neuropathic pain. However, the application of docking in virtual-screening in silico methods to drug discovery has some challenge but it allows us to make the directed and meaningful design of drugs fo...
Radiation therapy is potentially immunogenic yet it rarely generates long-term antitumor effects. We have recently demonstrated that Toll-like receptor 9 (TLR9) jump-starts the signal transduction and activator of transcription 3 (STAT3)-dependent vascularization and regrowth of tumors that recur upon irradiation. We propose that the targeted inhibition of the TLR9/STAT3 signaling axis in myelo...
OBJECTIVES There is a marked propensity for patients with acetaminophen-induced acute liver failure to develop sepsis, which may culminate in multiple organ failure and death. Toll-like receptors sense pathogens and induce inflammatory responses, but whether this is protective or detrimental in acetaminophen-induced acute liver failure remains unknown. DESIGN, SETTING, AND PATIENTS We assesse...
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...
TLR2 in association with TLR1 or TLR6 plays an important role in the innate immune response by recognizing microbial lipoproteins and lipopeptides. Here we present the crystal structures of the human TLR1-TLR2-lipopeptide complex and of the mouse TLR2-lipopeptide complex. Binding of the tri-acylated lipopeptide, Pam(3)CSK(4), induced the formation of an "m" shaped heterodimer of the TLR1 and TL...
Aim: Toll-like receptor 9 (TLR9) can recognize the DNA fragments released from chemotherapy-treated cancer cells in tumor tissues and induce an inflammatory response. The aim of present study w...
toll-like receptor 4 (tlr4), considered one of the most important tlr, recognizes lipopolysaccharide of gram-negative bacteria. recognition of ligands by tlrs induces signaling pathways resulting in activation of transcriptional factors such as nf-κb which are involved in the expression of inflammatory cytokines and chemokines. to prevent an inappropriate immune response, a complex ...
the innate immune system recognizes the presence of bacterial products through the expression of a family of membrane receptors known as toll-like receptors (tlrs). polymorphisms in tlrs have been shown to be associated with increased susceptibility to diseases such as inflammatory bowel disease. the aim of this study was to determine whether there was a correlation between polymorphisms of tlr...
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...
