ABSTRACT
Elevated serum free fatty acid levels are associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. Macrophages are recruited to atherosclerotic plaques and metabolic tissues during obesity and accumulate lipids, including free fatty acids. We investigated the molecular consequences of intracellular saturated free fatty acid accumulation in macrophages.
