Toll-like receptor TLR4 and MD-2 bound to lipopolysaccharide

PDB ID: 3FXI

Toll-like receptors recognize foreign molecules as part of the innate immune system. This structure includes the extracellular domain of TLR4 bound to the protein MD-2, which together recognize bacterial lipopolysaccharides.
