主 题:Anesthesia-arousal Brain glycogen General anesthesia Glycogen phosphorylase Glycogen synthetase Isoflurane
摘 要:General anesthesia severely affects the metabolites in the ***,principally stored in astrocytes and providing the short-term delivery of substrates to neurons,has been implicated as an affected ***,whether glycogen plays a pivotal role in modulating anesthesia-arousal remains ***,we demonstrated that isoflurane-anesthetized mice exhibited dynamic changes in the glycogen levels in various brain *** synthase(GS)and glycogen phosphorylase(GP),key enzymes of glycogen metabolism,showed increased activity after isoflurane *** blocking glycogenolysis with 1,4-dideoxy-1,4-imino-Darabinitol(DAB),a GP antagonist,we found a prolonged time of emergence from anesthesia and an enhancedδfrequency in the EEG(electroencephalogram).In addition,augmented expression of glycogenolysis genes in glycogen phosphorylase,brain(Pygb)knock-in(PygbH11/H11)mice resulted in delayed induction of anesthesia,a shortened emergence time,and a lower ratio of EEG-δ.Our findings revealed a role of brain glycogen in regulating anesthesiaarousal,providing a potential target for modulating anesthesia.
