[Monocytes/macrophages and lipidosis of the human aortic intima in atherosclerosis]. 1995

P V Chumachenko, and N M Cherpachenko, and V S Zhdanov

Immunomorphological and histochemical studies were carried out on the aorta serial sections of 20-40-year-old males. The results demonstrate that monocytes appear in the aortal intima after fat deposition. Intensification of lipoidosis in the aorta promotes an increase in monocyte count in the intima. Enzymes utilizing fat in the macrophages were not revealed at early stages of lipoidosis. Activation of lipoidosis is followed by the appearance of acid lipase, acid phosphatase and nonspecific esterase in monocytes. This is evidence of these cells capacity to phagocyte and utilize fat. The quantity of these cells increases with intensification of lipoidosis. Monocytes/macrophages are expressing HLA-DR antigen on their surface, this expressing their active immunological state.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed)	Lipid
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.
