Multiple sclerosis is characterised by immune-mediated demyelination. Astrocytes participate in both the inflammatory response and the formation of the classical MS plaque.

§ 1

Reactive astrocytes in MS lesions

Astrocytes become reactive in and around MS lesions, contributing to both inflammation and scar formation.201,190

§ 2

Emerging therapeutic angles

Modulating astrocyte phenotypes to favor repair rather than scarring is an active research direction.
