| abstractText | Multiple sclerosis (MS) is a neurological disorder that affects more than a million people worldwide. The etiology of MS is not known and there is no medical treatment that can cure MS. Earlier studies have shown that peroxisome proliferator-activated receptor (PPARs) agonists ameliorate MS-like disease in experimental allergic encephalomyelitis (EAE). In this study we have used PPARdelta deficient mice to determine its physiological role in the regulation of CNS EAE and MS. We found that PPARdelta(-/-) mice develop EAE with similar day of onset and disease incidence compared to C57BL/6 wild type mice. Interestingly, both male and female PPARdelta(-/-) mice showed prolonged EAE with resistance to remission and recovery. PPARdelta(-/-) mice with EAE expressed elevated levels of IFNgamma and IL-17 along with IL-12p35 and IL-12p40 in the brain and spleen. PPARdelta(-/-) mice also developed augmented neural antigen-specific Th1/Th17 responses and impaired Th2/Treg responses compared to wild type mice. These findings indicate that PPARdelta(-/-) mice develop prolonged EAE in association with augmented Th1/Th17 responses, suggesting a critical physiological role for PPARdelta in the remission and recovery of EAE. |
