FABP4 and atherosclerosis: A-FABP had an effect on atherosclerosis due to not only the dysregulation of systemic metabolism related with adipose tissue, as a result of the activation of macrophages, as it was reported that the expression of A-FABP in macrophages is induced by oxidized low-density lipoprotein (LDL) [6], but also Toll-like receptor activators [7].
