We can say without any exaggeration that both hexokinase and glycolysis are involved in the control of brain cells' life\u0000and death. To perform these pivotal roles, hexokinase occurs in four different isoforms in mammalian\u0000cells. Type I isozyme is best suited for energy generation, introducing glucose in glycolysis. In contrast, Type II and Type III isoforms product is directed to generation of NADPH through the pentose\u0000phosphate pathway, utilized in biosynthetic processes. Nevertheless, hexokinase has another unique\u0000property to accomplish its multiple functions: the capacity for mitochondrial binding. Linked to its\u0000role in apoptosis control, the binding of hexokinase inhibits the action of apoptosis inducers, such as\u0000Bax, from initiating the release of intramitochondrial proteins. Akt mediates HKII binding to mitochondria. Overexpression of the phosphatase SHIP2 reduces Akt activity and enhances apoptosis, emphasizing the role of hexokinase in cell death. Furthermore, hexokinase also participates in cellular\u0000signaling and functional regulation. Adding complexity to this multidimensional enzyme´s attributes,\u0000glycolysis occurs in aerobic or anaerobic situations. “Aerobic glycolysis” participates in the control of\u0000cell excitability, in synapse formation and neurite growth. Here we provide an overview of the multiple roles of hexokinase and glycolysis in neuronal metabolic association with astrocytes, oligodendrocytes, and microglia. We also provide an update on the role of hexokinase and glycolysis in microglia\u0000activation and in brain aging and neurodegenerative diseases.\u0000","PeriodicalId":10784,"journal":{"name":"Current Chemical Biology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74552267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
