Omega-3 fatty acids and endothelial leukocyte adhesion molecules

Prostaglandins Leukot Essent Fatty Acids. Feb-Mar 1995;52(2-3):191-5. doi: 10.1016/0952-3278(95)90021-7.

Abstract

Although dietary fatty acids can modulate atherogenesis and inflammation, the mechanisms by which this occurs are poorly understood. Induction in endothelial cells of adhesion molecules for circulating leukocytes and of inflammatory mediators by cytokines likely contributes to early phases of atherogenesis and inflammation. We report here that incorporation into cellular lipids of one specific fatty acid of the omega-3 family, docosahexaenoic acid (DHA), decreases cytokine-induced expression of endothelial leukocyte adhesion molecules, secretion of inflammatory mediators, and leukocyte adhesion to endothelial cells. These properties of DHA may contribute to antiatherogenic and antiinflammatory effects of omega-3 fatty acids.
