| Outline of Final Research Achievements |
It has been known that monoacylglycerol lipase (MAGL) is involved in wiring process of neural network in brain development, however, its pathological function in inflammatory condition remains unknown. We found that MAGL transcription was downregulated in neonatal brain subjected to hypoxic/ischemic stress and primary microglia treated with lipopolysaccharide (LPS). Microglial MAGL was transcriptionally regulated by Stat6 and its protein was rapidly degraded by proteasome in steady state. LPS treatment inhibited its degradation, resulting in its stabilization in microglia. Intrinsic MAGL was not prerequisite for LPS-dependent induction of several inflammatory cytokines such as IL6 in normoxic or hypoxic conditions, whereas it promoted phagocytosis mediated by Fcγ receptor in microglia.
