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 and its causal relationship with
endothelial dysfunction in atherosclerosis are less understood. Here, we review
the recent studies of inflammasome and its activation in endothelial cells, 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, a master regulator in cholesterol
biosynthesis, can be activated in a noncanonical manner, which leads to the
activation of the NOD-like receptor family pyrin domain-containing protein
inflammasome in macrophages and endothelial cells. Results from in-vitro and
in-vivo models suggest that sterol regulatory element-binding protein 2 is a key
molecule in aggravating proinflammatory responses in endothelial cells and
promoting atherosclerosis. SUMMARY: The SREBP-induced NOD-like receptor family
pyrin domain-containing protein 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.
