Neurodegenerative diseases are different and many-sided disorders affecting both the Central and the Peripheral Nervous System. Despite the very different peculiar features, all the neurodegenerative diseases are characterized by the neuronal degeneration, which may be the consequence of different processes, such as an altered protein accumulation, an axonal damage, or the exposure to toxic agents. The progressive neuronal death leads to disease progression, which is not effectively counteracted by the current symptomatic therapies. Among the newly proposed therapeutic approaches, encouraging results have been obtained with Mesenchymal Stem Cells (MSCs), adult stem cells initially proposed for their differentiation potential and for their immune-modulatory abilities. Here we first verified in vivo the protective potential of MSCs into an in vivo model of Multiple Sclerosis (MS), represented by Experimental Autoimmune Encephalomyelitis (EAE), demonstrating that intravenous administration of MSCs are able to ameliorate the clinical score and the functional skills, and to reduce demyelinated lesions. We then investigated in vitro the possible molecular mechanisms of MSC protective action, thus demonstrating that, besides immunomodulation, MSCs are able to support neuronal survival after toxic stimuli exposure by reducing the apoptosis and by inhibiting the Metalloprotease pathway, which is supposed to be involved in neurodegenerative disease progression. Moreover, MSCs are able to promote the axonal myelination through the modulation of p75 receptor. For all these abilities, MSCs can represent a promising therapeutic approach for the treatment of neurodegenerative disorders.
