Omega-3 fatty acids: mechanisms underlying 'protective effects' in atherosclerosis

Curr Opin Lipidol. 2013 Aug;24(4):345-50. doi: 10.1097/MOL.0b013e3283616364.

Abstract

Purpose of review: This article provides an updated review on mechanistic and molecular studies relating to the effects of n-3 fatty acids (FA) on inhibiting atherogenesis.

Recent findings: The effects of n-3 FA on modulating arterial lipoprotein lipase levels link to changes in lipid deposition in the arterial wall. Lipoprotein lipase expression in the arterial wall also relates to local macrophage-mediated inflammatory processes. Increasing evidence suggests that n-3 FA ameliorate inflammation, another key component in the development of atherosclerosis, including decreases in proinflammatory cytokine production. n-3 FA inhibit atherogenic signaling pathways and modulate the phenotypes of inflammatory leukocytes and their recruitment in the arterial wall.

Summary: New mechanistic insights into the antiatherogenic action of n-3 FA have emerged. These studies may contribute to future therapeutic advances in preventing mortality and morbidity associated with atherosclerosis.
