G6PD facilitates axon regeneration via clathrin-mediated endocytosis

Metabolic reprogramming is a hallmark of neuronal repair, yet the roles of glucose metabolism-related enzymes remain poorly understood. To investigate their functions, we employed a sciatic nerve injury model, taking advantage the intrinsic regenerative capacity of peripheral neurons. After sciatic nerve crush injury, dorsal root ganglia exhibited sustained upregulation of several enzymes in the pentose phosphate pathway. Notably, glucose-6-phosphate dehydrogenase (G6PD), the rate-limiting enzym
