A lipid-binding receptor reduces B cell activation in early atherosclerosis

GPR55 is a G protein–coupled receptor that is activated by endogenous lipid mediators. Our findings in experimental mouse models of atherosclerosis and human plaques indicate that GRP55 signaling is important for limiting B cell activation and humoral responses during hypercholesterolemia, which suggests that GPR55 signaling has an atheroprotective role.
