Platelet activation by oxidized low density lipoprotein is mediated by CD36 and scavenger receptor-A.
OBJECTIVE The interaction of platelets with low density lipoprotein (LDL) contributes to the development of cardiovascular disease. Platelets are activated by native LDL (nLDL) through apoE Receptor 2' (apoER2')-mediated signaling to p38(MAPK) and by oxidized LDL (oxLDL) through lysophosphatidic acid (LPA) signaling to Rho A and Ca2+. Here we report a new mechanism for platelet activation by ox...
متن کاملA specific CD36-dependent signaling pathway is required for platelet activation by oxidized low-density lipoprotein.
Platelet hyperactivity associated with hyperlipidemia may contribute to development of a prothrombotic state. We previously showed that oxidized low-density lipoprotein (oxLDL) formed in the setting of hyperlipidemia and atherosclerosis activated platelets in a CD36-dependent manner. We now show that mitogen-activated protein kinase c-Jun N-terminal kinase (JNK)2 and its upstream activator MKK4...
متن کاملCD36 N-terminal cytoplasmic domain is not required for the internalization of oxidized low-density lipoprotein.
The uptake of OxLDLs (oxidized low density lipoproteins) by CD36-expressing macrophages in the arterial intima and the subsequent 'foam cell' formation represents a crucial step in the initiation and development of atherosclerotic plaques. The present study has addressed the function of the CD36 N-terminal cytoplasmic domain in the binding and internalization of OxLDL. A selection of CD36 N-ter...
متن کاملCompare the Effect of Eicosapentaenoic Acid and Oxidized Low-Density Lipoprotein on the Expression of CD36 and Peroxisome Proliferator-Activated Receptor Gamma
Background: There is evidence that CD36 promotes foam cell formation through internalizing oxidized LDL (ox-LDL) into macrophages therefore, it plays a key role in pathogenesis of atherosclerosis. In addition, CD36 expression seems to be mediated by nuclear receptor peroxisome proliferator-activated receptor gamma (PPAR-γ). The aim of the present study was to evaluate and compare the effect of ...
متن کاملA macrophage receptor that recognizes oxidized low density lipoprotein but not acetylated low density lipoprotein.
The formation of cholesterol-loaded macrophage foam cells in arterial tissue may occur by the uptake of modified lipoproteins via the scavenger receptor pathway. The macrophage scavenger receptor, also called the acetylated low density lipoprotein (Ac-LDL) receptor, has been reported to recognize Ac-LDL as well as oxidized LDL species such as endothelial cell-modified LDL (EC-LDL). We now repor...
