The first function described for TLR4 was the recognition of exogenous molecules from pathogens (PAMPs), in particular LPS molecules from gram-negative bacteria. [13] As pattern recognition receptor, TLR4 plays a fundamental role in pathogen recognition and activation of innate immunity which is the first line of defense against invading micro-organisms.
TLR4 is the only TLR that uses all four adaptors. Complex consisting of TLR4, MD2 and LPS recruits TIR domain-containing adaptors TIRAP and MyD88 and thus initiates activation of NFκB (early phase) and MAPK. TLR4-MD2-LPS complex then undergoes endocytosis and in endosome it forms a signaling complex with TRAM and TRIF adaptors.

An interesting cooperation has been discovered between TLRs and NLRs, particularly between TLR4 and NOD1 in response to Escherichia coli infection. [25] Another proof of the cooperation and integration of the entire immune system has been shown in vivo, when TLR signaling was inhibited or disabled, NOD receptors took over role of TLRs. [26]

TLR4-IN-C34 (or C34) is a drug which acts as a potent and selective antagonist of Toll-like receptor 4 (TLR4). In animal studies it blocks TLR4-mediated cytokine release and has antiinflammatory effects.
TLRs are located either on the cellular surface (TLR1, TLR2, TLR4, TLR5, TLR6) or within endosomes (TLR3, TLR7, TLR8, TLR9) sensing extracellular or phagocytosed pathogens, respectively. TLRs are integral membrane glycoproteins with typical semicircular-shaped extracellular parts containing leucine-rich repeats responsible for ligand binding ...
