Reverse cholesterol transport is a multi-step process resulting in the net movement of cholesterol from peripheral tissues back to the liver first via entering the lymphatic system, then the bloodstream. [1] Cholesterol from non-hepatic peripheral tissues is transferred to HDL by the ABCA1 (ATP-binding cassette transporter). [2]
ABCA1 mediates the efflux of cholesterol and phospholipids to lipid-poor apolipoproteins (apoA1 and apoE) (reverse cholesterol transport), which then form nascent high-density lipoproteins (HDL). It also mediates the transport of lipids between Golgi and cell membrane .
Drugs in this class substantially increase HDL cholesterol, lower LDL cholesterol, and enhance reverse cholesterol transport. [citation needed]CETP inhibitors inhibit cholesterylester transfer protein (CETP), which normally transfers cholesterol from HDL cholesterol to very low density or low density lipoproteins (VLDL or LDL).
Atherosclerosis. Atherosclerosis contributes to about half of all deaths in Western countries, including the United States. Globally, it causes about 10 million deaths per year.. Atherosclerosis ...
Several steps in the metabolism of HDL can participate in the transport of cholesterol from lipid-laden macrophages of atherosclerotic arteries, termed foam cells, to the liver for secretion into the bile. This pathway has been termed reverse cholesterol transport and is considered as the classical protective function of HDL toward atherosclerosis.
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries. This is a chronic inflammatory disease involving many different cell types and is driven by elevated levels of cholesterol in the blood. [9]
This movement of cholesterol is known as reverse cholesterol transport and is a protective mechanism against the development of atherosclerosis, which is the principal cause of heart disease and stroke. SR-BI is crucial in carotenoid and vitamin E uptake in the small intestine.
Mechanism of action of CER-001. CER-001 is designed to mimic the natural structure and function of nascent HDL, also known as pre-beta HDL. [12] This mimicry stimulates cholesterol efflux from macrophages, captures cholesterol and eliminates it via reverse lipid transport (RLT) pathway, also known as reverse cholesterol transport (RCT) pathway.
