53 人體免疫系統中的innate immune反應透過Toll-like receptor 4會辨識下列細菌的那一種構造？

Endotoxin Ribosome Capsule Inclusion body

answer ENDOTOXIN

Toll-like receptor 4 is a protein that in humans is encoded by the TLR4 gene.^[1][2] TLR 4 is a toll-like receptor. It detects lipopolysaccharide on Gram-negative bacteria and is thus important in the activation of the innate immune system. TLR4 has also been designated as CD284 (cluster of differentiation284).
