Purpose of review: Great effort has been devoted to elucidate the molecular mechanisms by which inflammasome in macrophages contributes to atherosclerosis. Inflammasome in vascular endothelial cells (ECs) and its causal relationship with endothelial dysfunction in atherosclerosis are less understood. Here we review recent studies of inflammasome and its activation in ECs, and highlight such endothelial inflammatory response in atherosclerosis. Recent findings: Inflammasomes are critical effectors in innate immunity, and their activation in macrophages and the arterial wall contributes to atherogenesis. Sterol regulatory element-binding protein 2 (SREBP2), a master regulator in cholesterol biosynthesis, can be activated in a non-canonical manner, which leads to activation of the inflammasome NOD-like receptor family pyrin domain-containing protein (NLRP) in macrophages and ECs. Results from in vitro and in vivo models suggest that SREBP2 is a key molecule in aggravating pro-inflammatory responses in ECs, and promoting atherosclerosis. Summary: The SREBP-induced NLRP inflammasome and its instigation of innate immunity is an important contributor to atherosclerosis. Elucidating the underlying mechanisms will expand our understanding of endothelial dysfunction and its dynamic interaction with vascular inflammation. Furthermore, targeting SREBP-inflammasome pathways can be a therapeutic strategy for attenuating atherosclerosis.
