Neuregulin-1 facilitates myelin regeneration through microglia-mediated mechanisms in a mouse model of chronic demyelination
Restoring a brain protein accelerates myelin repair in chronic demyelination, suggesting a potential treatment direction for progressive multiple sclerosis.
This mouse study demonstrated that neuregulin-1 (NRG-1) deficiency is associated with impaired remyelination and that therapeutic NRG-1 restoration promotes myelin repair by restoring microglial function for cholesterol processing and myelin debris clearance in chronic demyelinated lesions. These findings support NRG-1 as a potential therapeutic target for progressive MS, a disease with very high unmet need and limited current treatments.
