الوصف: Objective— We tested the hypothesis that endothelial peroxisome proliferator–activated receptor-γ protects against vascular thrombosis using a transgenic mouse model expressing a peroxisome proliferator–activated receptor-γ mutant (E-V290M) selectively in endothelium. Approach and Results— The time to occlusive thrombosis of the carotid artery was significantly shortened in E-V290M mice compared with nontransgenic littermates after either chemical injury with ferric chloride (5.1±0.2 versus 10.1±3.3 minutes; P =0.01) or photochemical injury with rose bengal (48±9 versus 74±9 minutes; P =0.04). Gene set enrichment analysis demonstrated the upregulation of NF-κB target genes, including P-selectin, in aortic endothelial cells from E-V290M mice ( P P P =0.02). The shortened time to arterial occlusion in E-V290M mice was reversed by administration of P-selectin–blocking antibodies or neutrophil-depleting antibodies ( P =0.04 and P =0.02, respectively) before photochemical injury. Conclusions— Endothelial peroxisome proliferator–activated receptor-γ protects against thrombosis through a mechanism that involves downregulation of P-selectin expression and diminished P-selectin–mediated leukocyte–endothelial interactions.
