Global or macrophage-specific knockout of Trpm2, which encodes the calcium-permeable ion channel TRPM2, protects mice against atherosclerosis induced by a high-fat diet. Mechanistically, activation of TRPM2 and the scavenger receptor CD36 promote the transformation of macrophages into inflammatory foam cells, thereby accelerating the development and progression of atherosclerosis.
