Lecithin-cholesterol acyltransferase (LCAT) catalyzes the intravascular synthesis of lipoprotein cholesteryl esters by converting cholesterol and lecithin to cholesteryl ester and lysolecithin. LCAT is unique in that it catalyzes sequential reactions within a single polypeptide sequence, a phospholipase A2 reaction followed by a transacylation reaction. In this report we find that LCAT mediates...
The breakdown of phospholipids in animal tissues has for long been regarded as involving the removal of the fatty acid residues by the successive action of phospholipases A and B, followed, in lecithin breakdown, for example, by the degradation of the glycerylphosphorylcholine so formed by means of a specific diesterase. The initial removal of a single fatty acid from the phospholipid molecule ...
A unique feature of lipoprotein lipase (LpL), the rate-limiting enzyme in the hydrolysis of circulating triglycerides, is its movement from its cell of synthesis, adipocyte or myocyte, to its site of action, the luminal endothelial surface. This involves processes that allow LpL to be released from the adipocyte cell surface and transferred against the flow of interstitial fluid to the luminal ...
We used a bone marrow transplantation approach to distinguish the activities of bone marrow-derived macrophages from the activities of central nervous system-resident microglia in phenomena associated with axon demyelination and remyelination. We transplanted wild type or germline NG2 null beta-actin-EGFP expressing bone marrow into irradiated wild type or NG2 null recipient mice, followed by a...
