Blood samples withdrawn from patients diagnosed with Relapsing-Remitting Multiple Sclerosis (RRMS) about to be started on interferon-β treatment and age and gender-matched healthy controls will be extracted and cultured. Exosomes will be isolated from the culture supernatants, phenotyped and added to dendritic cell (DC) cultures. The cytokine expression profile of DCs will be recorded and compared between MS patients and controls. Patients will also be clinically assessed using the Expanded Disability Scale Scores (EDSS).
