Objective: Atherosclerosis is a chronic multifactorial and inflammatory disease of large and medium arteries and the leading cause of cardiovascular diseases worldwide. The aim of this study was to investigate whether and how the nSMase2 (type 2-neutral sphingomyelinase), a key enzyme of sphingolipid metabolism, may contribute to the development of atherosclerotic lesions.
Approach And Results: The role of nSMase2 in atherosclerosis was investigated in mice, mutant for nSMase2, and in mice intraperitoneally injected with GW4869, a pharmacological nSMase2 inhibitor.
