The purpose of this research is to characterize the effect of teriflunomide on the activation of B-cells, as well as its capacity to modify B-cell cytokine secretion. The in-vitro identified effects of teriflunomide on the expression of B-cell activation markers, costimulatory and antigen presenting molecules, as well as on cytokine secretion, will then be confirmed in a cohort of Relapsing Remitting Multiple Sclerosis (RRMS) patients treated with this medication.

Neurology/MS clinic: patients with Relapsing Remitting MS "Treatment naïve Relapsing Remitting MS patients will be recruited to provide samples for the in vitro tests. In addition, Relapsing Remitting MS patients who are already receiving treatment with teriflunomide as a part of their routine care will be recruited to obtain blood samples for the in vivo testing."
