Treatment of experimental autoimmune encephalomyelitis (EAE) with resveratrol, an activator of sirtuin 1 (SIRT1), reduces disease severity. This suggested that activators of SIRT1, a highly conserved NAD-dependent protein deacetylase, might have immune-modulating or neuroprotective therapeutic effects in EAE. Previously, we
