초록/해제  
요약Sphingolipids are critical amphipathic molecules present in all eukaryotic cell membranes that are enriched in the developing and adult brain. Though strongly implicated in most neurological diseases, how sphingolipids function in and between brain cells in vivo remains largely enigmatic. Here we dissect the brain functions of Glucocerebrosidase (GBA), a conserved lysosomal hydrolase for sphingolipid catabolism, in a Drosophila model. We identify that glia produce GBA for sphingolipid degradation and neural lysosomal function, and demonstrate that glial gba1bknockout causes diurnal protein aggregate formation, sleep loss, and impaired neurite remodeling in a dynamic circadian circuit that grows and shrinks each day. Remarkably, lipidomics targeted across both time and age revealed diurnal fluctuations in sphingolipids during adulthood as well as a unique sphingolipidome during brain development. The developmental sphingolipidome is characterized by glial catabolism and coordinated neural biosynthesis, and developmental sphingolipids dominate adult patterns of substrate accumulation in glial catabolic mutants. The striking compartmentalization of sphingolipid metabolism between glia and neurons likely acts to finetune neuronal structure and function during both development, adult remodeling, and disease.
