AMPK→remyelination and neuroinflammation suppression
Metformin activates AMPK, which suppresses neuroinflammation and promotes oligodendrocyte progenitor cell differentiation and remyelination — both central to multiple sclerosis pathology. Evidence includes animal models of experimental autoimmune encephalomyelitis and early clinical data, with 8/8 supportive co-mentions and papers up to 2025.
