Apolipoproteins modulate the inflammatory response to lipopolysaccharide

An increasing body of evidence demonstrates a close interplay between lipoprotein metabolism and sepsis. Sepsis results in an increase of plasma triglycerides within VLDL as a consequence of an enhanced hepatic VLDL production and/or inhibited peripheral and hepatic VLDL clearance. In contrast, sepsis decreases plasma cholesterol within LDL and...

Apolipoprotein C-I binds free fatty acids and reduces their intracellular esterification

Mice that overexpress human apolipoprotein C-I (apoC-I) homozygously (APOC1+/+ mice) are protected against obesity and show cutaneous abnormalities. Although these effects can result from our previous observation that apoC-I inhibits FFA generation by LPL, we have also found that apoC-I impairs the uptake of a FFA analog in adipose tissue. In...
