Abstract

Glatiramer acetate (GA) is efficacious in reducing demyelinating-associated exacerbations in patients with relapsing-remitting multiple sclerosis (RRMS) and in several experimental autoimmune encephalomyelitis (EAE) models. Here we report that GA reduced the clinical and pathological signs of mice in chronic EAE induced by myelin oligodendrocyte glycoprotein (MOG). GA-treated mice demonstrated only mild focal inflammation, and less demyelination, compared with controls. Moreover, we also found minimal axonal disruption, as assessed by silver staining, antibodies against amyloid precursor protein (APP) and non-phosphorylated neurofilaments (SMI-32), in the GA-treated group. In conclusion, our study demonstrated for the first time that axonal damage is reduced following GA treatment in C57/bl mice with chronic MOG-induced EAE.
