Relapsing-remitting (RRMS), a most common form of MS, is characterized by acute attacks alternated by partial or complete recovery periods. The major focus of our research is to identify the therapeutic target using metabolomics. Metabolomics is a fast emerging field which can provide a direct “functional readout of the physiological state” of an organism. Identification of blood-based metabolic pathway(s) in relapsing-remitting form of MS (RRMS) which could be used for therapy. Using untargeted ultra-performance liquid and gas mass spectrometry, we measured serum metabolites from 33 RRMS patients, and 14 healthy subjects (HS). A total of 621 known metabolites were detected and 60 metabolites were significantly altered in the serum of RRMS compared to HS. Bioinformatics analysis revealed four metabolic pathways altered in RRMS including glycerophospholipid, citrate cycle, sphingolipids, and pyruvate metabolism. PBMCs isolated from RRMS patients exhibited higher glycolysis suggesting altered metabolic state of immune cells. EAE mice treated with glycolytic inhibitor 2-deoxyglucose (2-DG; once daily), resulted in a significantly delayed (P
