Abstract

Lecithin:cholesterol acyltransferase (LCAT) is postulated to take care of excess cholesterol formed during metabolism of triglyceride (TG)-rich lipoproteins. To test this hypothesis the relationship between secretion of LCAT and TG have been investigated in rats with ventromedial hypothalamic lesions which lead to increased hepatic secretion of TG. 1. The increased plasma concentration of TG in rats with ventromedial hypothalamic lesions was positively correlated to the activity of LCAT in plasma. 2. Incubation of hepatocytes isolated from such rats revealed a positive linear correlation between secretion of TG and of LCAT. 3. The secretion of unesterified cholesterol was neither correlated to the secretion of the acyltransferase nor to the TG.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
