Abstract:
Lipid-processing mechanisms during demyelination are poorly understood. In this issue of Neuron,Nugent et al. (2020) show by cell-specific lipidomics that Trem2 deficiency leads to cholesterol ester (CE) overload in microglia. This is mediated by misregulation of lipid metabolism genes and is rescued by modulating CE synthesis or efflux.
