Abstract
Increasing evidence has implicated the membrane protein CD36 (or fatty acid translocase, FAT) to be involved in high affinity fatty acid uptake. CD36 is expressed in tissues active in fatty acid metabolism, like adipose tissue and skeletal and cardiac muscle, but also in intestine. CD36 is localized in the intestine mainly in the jejunal villi, where it is confined to enterocyte apical membrane.
The aim was to determine the role of CD36 in intestinal lipid absorption. Lipid absorption was determined by administering 3H-labeled triolein and l4C-labeled palmitic acid as an olive oil bolus by intragastric gavage and determine appearance of 3H and 14C label in plasma, after blocking lipolysis by i.v. injections of Triton WR 1339. Surprisingly, no differences in plasma appearance of 3H-label or l4C-label were observed in CD36−/−mice compared to wild type controls. These results suggest that CD36 does not play a role in intestinal lipid absorption after an acute lipid load. (Mol Cell Biochem 239: 199–202, 2002)
