RIPK3 and atherosclerosis: If previous reports are correct that RIPK3 increases atherosclerosis severity and that necroptotic macrophages are the main source of that increase in severity, then we would expect to see less atherosclerotic phenotypic severity in the Ripk3ΔGlobal, Ripk3ΔHet, and Ripk3ΔMΦ-Cre mice.
