MD-2 as the target of nonlipid chalcone in the inhibition of endotoxin LPS-induced TLR4 activity.
Myeloid differentiation 2 (MD-2) recognizes endotoxin lipopolysaccharide (LPS), which is required for Toll-like receptor 4 (TLR4) activity. MD-2 represents a more attractive therapeutic target than… Expand
