7-keto Cholesterol is a bioactive sterol and a major oxysterol component of oxidized LDL.{26766,5829} It is produced by oxidation of cholesterol via ethanol-mediated lipid peroxidation or photodamage as well as oxidation of 7-dehydro cholesterol (Item No. 14612) by the cytochrome P450 (CYP) isoform CYP7A1.{26764,26765,26761} 7-keto Cholesterol inhibits CYP7A1 (IC50 = ~1 ?M).{26765} It induces activation and chemotaxis of retinal microglia as well as polarization to a pro-inflammatory state via NLRP3 inflammasome activation in vitro.{39975} Intraocular implantation of 7-keto cholesterol coated wafers increases ocular levels of VEGF, IL-1?, and GRO/KC, macrophage infiltration, and neovascularization in rat eye.{39976} Levels of 7-keto cholesterol in lipid deposits are increased in a variety of chronic diseases, including atherosclerosis, Alzheimer’s disease, and age-related macular degeneration.
