We show that TLR2 associates with the high-affinity LPS binding protein membrane CD14 to serve as an LPS receptor complex , and that LPS treatment enhances the oligomerization of TLR2 .
 ( protein: TLR2, None) , ( protein: TLR2, None) , ( protein: LPS receptor complex, None) , ( protein: high-affinity LPS binding protein, None) , ( protein: CD14, None)
