Foam cell accumulation in arterial walls is the critical initiating event of atheroma plaque development. Macrophages acquire this phenotype by cholesterol ester accumulation and pro-inflammatory signaling pathways activation. Oxydized form of cholesterol activates LXR and subsequently atheroprotective cellular cholesterol efflux. In parallel, crystallized cholesterol phagocytosis will impair vesicular traffic, activating NLRP3 and deleterious IL-1 cytokines release. Here we describe further those pathways in human macrophages and to evidence new key factors in atherosclerosis development. First, stimulation of cellular cholesterol efflux to ApoA-I and HDL from human macrophage by LXR agonist is LXRα-dependent. Transcriptional activation of...
