- Abstract:
- Multiple sclerosis (MS) is a chronic debilitating disease of unknown etiology. The disease has a seasonal exacerbation of clinical symptoms, which are frequently described in spring and summer. However, the mechanisms of such seasonal exacerbations remain unknown. In this study, we used targeted metabolomics analysis of serum samples using LC-MC/MC to determine seasonal changes in metabolites. We have found changes in multiple metabolites which differed depending on season. The ceramides, belonging to the sphingolipid pathway, were found activated in spring-summer (SS) and fall-winter (FW) MS, suggesting their central role in disease pathogenesis. Our identification of ceramide activation suggests a mechanism of neuron damage in MS which could be further investigated as therapeutic targets.
