Abstract The neutral sphingomyelinases (N-SMases) are a group of Mg²⁺-dependent enzymes with a pH optimum in the neutral range. N-SMases catalyze the conversion of sphingomyelin to ceramide and have been found particularly enriched in brain tissue. N-SMase activity has been implicated in many physiological and pathological processes affecting the brain and nervous system. In this review, we discuss the proposed functions of N-SMase with a particular emphasis on its role in neurological disorders, such as age-related neurodegeneration, Alzheimer's disease, HIV-associated dementia, atherosclerosis, ischemia-reperfusion injury, and cancer.
