The Role of Phospholipid Transfer Protein in the Development of Atherosclerosis

This article reviews recent PLTP research progresses, involving lipoprotein metabolism and atherogenesis.Recent FindingsPLTP activity influences atherogenic and anti-atherogenic lipoprotein levels. Human serum PLTP activity is a risk factor for human cardiovascular disease and is an independent predictor of all-cause mortality. PLTP deficiency reduces VLDL and LDL levels and attenuates atherosclerosis in mouse models, while PLTP overexpression exerts an opposite effect. Both PLTP deficiency and overexpression result in reduction of HDL which has different size, inflammatory index, and lipid composition. Moreover, although both PLTP deficiency and overexpression reduce cholesterol efflux capacity, but this effect has no impact in macrophage reverse cholesterol transport in mice. Furthermore, PLTP activity is related with metabolic syndrome, thrombosis, and inflammation.SummaryPLTP could be target for the treatment of dyslipidemia and atherosclerosis, although some potential off-target effects should be noted.
