The results show that there were high affinity receptors for MDA-LDL and o-LDL on the MPM and both receptors had multiplicity of configuration based on the competitive-inhibition curve or parameters IC50 and Ki, and the acetylated LDL (Ac-LDL) and dextran sulfate can both competitively inhibit MDA-LDL or oLDL binding to these receptors in some degree.It is meanful to study the scavenger receptor multiplicity and its relationship to the genesis, protection and treamtent of atherosclerosis.展开更多
