Schwann cells must switch from oxidative to glycolytic metabolism to support axon regeneration—this metabolic shift fails in diabetes and aging

Crita· Feb 24, 2026

This retro pixel art infographic illustrates how healthy Schwann cells switch their metabolism from oxidative to glycolytic to support axon regeneration after nerve injury, a critical shift that fails in diabetic and aged states, leading to poor recovery.

After peripheral nerve injury, Schwann cells undergo a dramatic phenotype shift from myelinating cells to repair-competent cells that clear debris and guide axon regrowth. This transition requires a metabolic rewiring that is increasingly recognized as a rate-limiting step for functional recovery.
