Targeting cholesterol metabolism in macrophages to eliminate viral infection

Recent evidence suggests a link between cholesterol metabolism and innate immunity. Upon viral infection, macrophages show reduced cholesterol synthesis accompanied by enhanced expression of antiviral genes, including type I interferon (IFN-I). IFN-I can induce 25-hydroxycholesterol (25-HC) accumulation, which blocks viral entry. However, it has been unclear whether other cholesterol-associated metabolic products or enzymes regulate innate…
