WebThe MyD88-dependent way is responsible for proinflammatory cytokine expression. Upon LPS stimulation, the intracellular TIR region of TLR4 binds to the carboxyl terminus of MAL and MyD88, while the amino terminus of MyD88 recruits IRAK4 (IL-1 receptor-associated kinase-4), IRAK1, IRAK2 through homotypic interactions [9]. WebTLR4 is activated by lipopolysaccharide (LPS, endotoxin) of Gram-negative bacteria and sequentially triggers two signaling cascades: the first one involving TIRAP and MyD88 …
