Crystal Clots as Therapeutic Target in Cholesterol Crystal Embolism.

Rationale: Cholesterol crystal embolism can be a life-threatening complication of advanced atherosclerosis. Pathophysiology and molecular targets for treatment are largely unknown. Objective: We aimed to develop a new animal model of cholesterol crystal embolism to dissect the molecular mechanisms of cholesterol crystal (CC)–driven arterial occlusion, tissue infarction, and organ failure. Methods and Results: C57BL/6J mice were injected with CC into the left kidney artery. Primary end point was glomerular filtration rate (GFR). CC caused crystal clots occluding intrarenal arteries and a dose-d... Mehr ...
