背景信息：TLR4. TLR4 is a 100 kDa type I transmembrane glycoprotein that belongs to the mammalian Toll‑Like Receptor family of pathogen pattern recognition molecules. The complex of TLR4 with MD‑2 functions as a critical receptor for bacterial endotoxin/lipopolysaccharide (LPS) (1-3). Mature human TLR4 consists of a 608 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 187 aa cytoplasmic domain. TLR4 contains 21 leucine rich repeats in its ECD and one cytoplasmic Toll/IL‑1 receptor (TIR) domain (4). The ECD of human TLR4 shares approximately 25% aa sequence identity with other human TLRs and 60%-74% aa sequence identity with bovine, equine, feline, mouse, rat, and porcine TLR4. On monocytes, macrophages, dendritic cells, and B cells, MD-2 expression is required for cell surface localization of TLR4 and for optimal LPS-induced TLR4 signaling (5-8). MD-2 also forms soluble disulfide‑linked homo‑oligomers which can interact with TLR4 (6). Through a domain separate from its TLR4-binding domain, MD-2 extracts LPS from circulating CD14-LPS complexes and carries the LPS into a ternary complex with TLR4 (9-11). The interaction of MD-2/LPS with TLR4 induces receptor oligomerization and the triggering of an inflammatory response (2, 12). Increased levels of plasma MD-2 in septic shock patients sensitizes MD-2 non-expressing epithelial cells to LPS and promotes widespread tissue inflammation (13).
