Intravenous administration of bone marrow-derived mesenchymal stem cells induces a switch from classical to atypical symptoms in experimental autoimmune encephalomyelitis.

ABSTRACT: Potent immunosuppressive and regenerative properties of mesenchymal stem cells (MSCs) position them as a novel therapy for autoimmune diseases. This research examines the therapeutic effect of MSCs administration at different disease stages in experimental autoimmune encephalomyelitis (EAE). Classical and atypical scores of EAE, associated with Th1 and Th17 response, respectively, and also Treg lymphocytes, were evaluated. MSCs administration at the onset (EAE+MSConset) induced an important amelioration of the clinical signs and less lasting effect at the peak of EAE (EAE+MSCpeak). No effect was observed when MSCs were applied after EAE stabilization (EAE+MSClate). Surprisingly, EAE atypical signs were detected in EAE+MSCpeak and EAE+MSClate mice. However, no correlation was found in Th17/
