SEP-MIR is a prospective, single-center, descriptive study.
Participants will be recruited among adult patients with RRMS coming for a follow-up consultation in the Neurology Department, Nervous System Diseases Pole, at the hôpital Pitié - Salpêtrière (Paris).
As this is a descriptive study, the recruitment of 20 participants (10 patients with relapsing-remitting MS and 10 patients with relapsing-remitting MS) should meet the objectives of this study.
A 50 ml blood sample will be obtained from each participant and several clinical data regarding their pathology will be collected.
