Description: | 25-Hydroxycholesterol is a metabolite of cholesterol that is produced and secreted by macrophages in response to Toll-like receptor (TLR) activation. 25-hydroxycholesterol is a potent (EC50≈65 nM) and selective suppressor of IgA production by B cells. |
Target: | Human Endogenous Metabolite |
In Vitro: | The synthesis of 25-hydroxycholesterol is catalyzed by the enzyme cholesterol 25-hydroxylase, which uses cholesterol and molecular oxygen as substrates and NADPH as a cofactor. 25-hydroxycholesterol is a potent bioactive lipid in the innate and adaptive immune systems[1]. |
