The present invention provides a family of non-naturally occurring polypeptides having cholesterol efflux activity that parallels that of full-length apolipoproteins (e.g., Apo AI and Apo E), and having high selectivity for ABCA1 that parallels that of full-length apolipoproteins. Further, the peptides of the invention have little or no toxicity when administered at therapeutic and higher doses. The invention also provides compositions comprising such polypeptides, methods of identifying, screening and synthesizing such polypeptides, and methods of treating, preventing or diagnosing diseases and disorders associated with dyslipidemia, hypercholesterolemia and inflammation.

The present invention relates to a cell culture system to provide a tool for assessing the potential of a patient's serum for preventing the accumulation of cholesterol in arteries (i.e. serum efflux potential) that leads to atherosclerosis and to screen new drug compositions being developed to reduce the accumulation of cholesterol or enhance the clearance of cholesterol from the vessel wall. The present invention combines two individual assays, which are two different cholesterol assays: an assay measuring scavenger receptor class B type I (SR-BI)-mediated cholesterol efflux and an assay measuring ATP binding cassette protein 1 (ABCA1)-mediated cholesterol efflux, and uses them in parallel to test human and animal sera for their potential to stimulate efflux, as mediated by either of the two receptors described above.

The invention belongs to the field of biochemical engineering, and in particular relates to a chemical synthetic method of a low affinity ligand of an oxidized low density lipoprotein receptor CD36. The method comprises the following steps of: carrying out a chemical reaction on 4-Dimethylaminopyridine, N, N'-Dicyclohexylcarbodiimide, azelaic acid and 7-ketocholesterol; and obtaining oxLig-1 through extraction, sample mixing, packing, purification and collection. Experiments show that the chemically synthesized oxLig-1 has same physiological activity with that of oxLig-1 separated and purified from oxLDL (oxidized low density lipoprotein), and the oxLig-1 activates cell signaling mediated by CD36. According to the chemical synthetic method disclosed by the invention, oxLig-1 is synthesized by the chemical method, and oxLig-1 has a completely consistent chemical structure with that of the low affinity ligand of CD36 and can activate ERK (Extracellular Signal-Regulated Kinase) and JNK (Jun N-Terminal Kinase) and up-regulate expression of a cholesterol outflow gene, namely, a triphosadenine binding cassette transporter A1 (ABCA1).
