Lower brain-derived neurotrophic factor in serum of relapsing remitting MS: Reversal by glatiramer acetate

Neuronal growth factors may exert a neuroprotective effect in multiple sclerosis (MS). We found reduced levels of brain-derived neurotrophic factors (BDNF) in the serum and CSF of relapsing-remitting MS patients, which was reversed by therapy with glatiramer acetate. BDNF may play a protective role in MS, and immunomodulation therapy, such as with glatiramer acetate, may enhance the action this mechanism.
