    摘要: The present invention provides novel methods for treating and preventing coronary artery disease in HIV-1-infected individuals by interfering with Nef-mediated effect on ABCA1. The invention further provides novel methods for suppressing HIV infection by stimulating cholesterol efflux from cells by stimulating expression of ABCA1 in HIV-1-infected individuals. These methods take advantage of the finding that Nef, a regulatory protein of HIV-1, (1) diminishes expression of ATP-binding cassette transporter A1 (ABCA1), the main transporter of cholesterol from cells to extracellular acceptors; and (2) impairs cholesterol efflux from HIV-1-infected macrophages leading to cholesterol accumulation and formation of foam cells, which is a characteristic feature of atherosclerosis.
