Acid sphingomyelinase (ASM) is a sphingolipid metabolizing enzyme that catalyzes the hydrolysis of sphingomyelin to ceramide, and previous work has shown it is upregulated in models of Alzheimer’s disease. Here the authors demonstrate in a mouse model of Alzheimer’s disease that antibody-based immunotherapy targeting plasma ASM resulted in attenuated neuropathological features by suppressing pathogenic Th17 cells.
