Cholesterol accumulation in macrophages drives NETosis in atherosclerotic plaques via IL-1β secretion

Abstract

These studies establish a new link between inflammasome-mediated IL-1β production in macrophages and NETosis in atherosclerotic plaques. Macrophage-derived IL-1β appears to increase NETosis both by increasing neutrophil recruitment to plaques and by promoting neutrophil NLRP3 inflammasome activation.
