Age-related macular degeneration(AMD)involves dysregulation of the innate immune response of complement and mononuclear phagocytes and abnormalities of local microglia.When microglia transition from a resting state to an active state,their metabolic pathway also changes,known as"metabolic reprogramming",and their glucose metabolic reprogramming is a key factor in the pathogenesis of AMD,involving multiple signaling pathways.Including phosphatidylinositol 3-kinase-serine threonine kinase-rapamycin target,adenylate activated protein kinase and hypoxia-inducing factor 1 pathway.These metabolic changes regulate the inflammatory response,energy supply,and neuroprotective functions of microglia.Therapeutic strategies to regulate the reprogramming of glucose metabolism in microglia have achieved initial results.Future studies should further explore the mechanisms of microglia metabolic regulation to develop new targeted drugs and intervene in the treatment of AMD through anti-cellular aging pathways.
