Microglia clean up toxic lipids in multiple sclerosis

Dong and colleagues investigated mechanisms mediating neurodegeneration in multiple sclerosis and identified a direct role for oxidized phosphatidylcholines (OxPCs) in driving CNS cell death. Microglia activity, mediated by the lipid sensor TREM2 and a neutralizing OxPC antibody, were capable of rescuing OxPC-induced neurotoxicity.
