TLR 4 - Wikipedia, The Free Encyclopedia
Toll-like receptor 4 is a protein that in humans is encoded by the TLR4 gene. TLR 4 is a toll-like receptor. It detects lipopolysaccharide from Gram-negative bacteria and is thus important in the activation of the innate immune system. TLR 4 has also been designated as CD284 (cluster of ... Read Article
