Our aim was to assess the reaction of TNFα, resistin, leptin and adiponectin to lipid infusion. Eight healthy subjects underwent a 24-hour lasting infusion of lipid emulsion. Plasma concentrations and expressions of selected cytokines in subcutaneous fat were measured. TNFα plasma concentration did not change during the first 4 hours of hypertriglyceridemia, but a significant increase after 24 hours was detected (p<0.001 for 0; 30; 240 min vs. 24 h). Plasma concentration of resistin significantly increased at 30 min of infusion and remained elevated (p<0.01 for 0 min vs. 30; 240 min; p<0.001 for 0 min vs. 24 h). Plasma concentrations of leptin and adiponectin did not show any significant changes. Although the expression of resistin in the subcutaneous adipose tissue tended to increase, the change was not significant. Expressions of TNFα, leptin and adiponectin were unaffected. In conclusions, our results indicate that acutely induced hyperlipidemia could influence the secretion of TNFα and resistin.

    Conjugated linoleic acid (CLA) is a naturally occurring group of dienoic derivatives of linoleic acid found in beef and dairy products. CLA has been reported to reduce body fat. To examine the mechanism(s) of CLA reduction of fat mass, female C57BL/6J mice were fed standard semipurified diets...

    The A-ZIP=F-1 mouse is lacking virtually all white adipose tissue. Like humans with extensive deficiencies of adipose tissue, the A-ZIP=F-1 mice develop a severe form of insulin resistant diabetes. We have studied the physiology of the A-ZIP=F-1 mice. Their adaptation to fasting is notable for...

    Adiponectin and leptin are adipose hormones closely linked to body fat content, fat distribution and insulin sensitivity. In Caucasians the relationship of these hormones to fat and insulin sensitivity are well described; however, these relationships are less well understood in African Americans...

This could be why not all obese people are diabetic. Adiponectin...

    Obesity is an inflammatory state characterized by an augment in circulating inflammatory factors. Leptin may modulate the synthesis of these factors by white adipose tissue decreasing insulin sensitivity. We have examined the effect of chronic central administration of leptin on circulating...
