WebFeb 17, 2009 · Toll-like receptor 4 (TLR4), the signal-transducing molecule of the LPS receptor complex, plays a fundamental role in the sensing of LPS from Gram-negative bacteria. Activation of TLR4 signaling pathways by LPS is a critical upstream event in the pathogenesis of Gram-negative sepsis, making TLR4 an attractive target for novel … WebOct 21, 2010 · LPS is the well-characterized PAMP for TLR4, and is the principal glycolipid component of the outer membrane of Gram-negative bacteria. TLR4 plays an important role in mediating LPS-induced inflammatory signaling and infectious diseases.
WebMay 1, 2008 · Upon LPS recognition, TLR4 undergoes oligomerization and recruits its downstream adaptors through interactions with the TIR (Toll-interleukin-1 receptor) domains. TIR domains contain three highly conserved regions, which mediate protein–protein interactions between the TLRs and signal transduction adaptor proteins. WebThe pattern recognition receptor TLR4 recognizes lipopolysaccharide (LPS), a component of the cell wall of Gram-negative bacteria. Ligand binding to TLR4 stimulates two distinct signaling pathways, and different LPS types and their derivatives can bias signaling through either pathway depending on their composition, which has implications for the use of …
