The inverse relationship between HDL and apolipoprotein A-I concentrations and the risk for premature atherosclerosis is well established, but the mechanism whereby apolipoprotein A-I offers protection is still somewhat elusive. Recent studies suggest that a specific subpopulation within the lipoprotein (AI) subclass may be more effective than others in promoting cholesterol efflux from cells. In addition, it appears that the lipid-free form of apolipoprotein A-I may have an important role in the antiatherosclerotic process. Unique new functions of apolipoprotein A-I-containing particles in modulating cytokines and lipid hydroperoxide transport, together with their role in antiatherogenesis, are also discussed. Current research with transgenic mice, however, indicates that apolipoprotein A-II must be taken into consideration in understanding the development of atherosclerosis, because it appears to be a potent antagonist for the protective properties of apolipoprotein A-I.

UI	MeSH Term	Description	Entries
D008052	Lipid Metabolism, Inborn Errors	Errors in the metabolism of LIPIDS resulting from inborn genetic MUTATIONS that are heritable.	Lipid Metabolism, Inborn Error
D008074	Lipoproteins	Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes.	Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating
D008822	Mice, Transgenic	Laboratory mice that have been produced from a genetically manipulated EGG or EMBRYO, MAMMALIAN.	Transgenic Mice,Founder Mice, Transgenic,Mouse, Founder, Transgenic,Mouse, Transgenic,Mice, Transgenic Founder,Transgenic Founder Mice,Transgenic Mouse
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D002784	Cholesterol	The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.	Epicholesterol
D004195	Disease Models, Animal	Naturally-occurring or experimentally-induced animal diseases with pathological processes analogous to human diseases.	Animal Disease Model,Animal Disease Models,Disease Model, Animal
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001161	Arteriosclerosis	Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involved, such as ATHEROSCLEROSIS with fatty lesions in the ARTERIAL INTIMA of medium and large muscular arteries.	Arterioscleroses
