Lipopolysaccharide-induced insulin resistance in monolayers of cultured hepatocytes.

Abstract

In order to clarify the endotoxin effect on the hepatic removal of insulin, the influence of lipopolysaccharide (LPS) from E. coli 0111:B4 on the insulin binding and endocytosis in cultured hepatocytes from adult male rats has been investigated. LPS decreases both processes in a time and temperature-dependent manner, showing a major effect at short time and low temperature, according to the characteristics of LPS binding and uptake.
