Identification of Substituted Pyrimido[5,4-b]indoles as Selective Toll-Like Receptor 4 Ligands
A cell-based high-throughput screen to identify small molecular weight stimulators of the innate immune system revealed substituted pyrimido[5,4-b]indoles as potent NFκB activators. The most potent hit compound selectively stimulated Toll-like receptor 4 (TLR4) in human and mouse cells. Synthetic modifications of the pyrimido[5,4-b]indole scaffold at the carboxamide, N-3, and N-5 positions reve...
متن کاملIn silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli
Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...
متن کاملMonocyte Expression of Toll-like Receptor-4 in Patients with Stable Angina Undergoing Percutanoeus Coronary Intervention
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 ...
متن کاملToll Like Receptor 2 and 4 Expression in Peripheral Blood Mononuclear Cells of Multiple Sclerosis Patients
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...
متن کاملtoll-like receptor 4 in ventilator-induced lung injuries
toll like receptors (tlrs) recognize pathogens and generate an immediate defense response by inducing the production of pro-inflammatory cytokines, which rapidly destroy or limit the pathogens. in their bridging role, tlr downstream signals link innate and adaptive immunity, particularly by mediating dc maturation and activation of pathogen specific t lymphocytes. these pathways lead to the act...
