About this trial

In the sponsor's words

MS is a heterogeneous disease either in its response to treatment or clinical manifestation. Indeed, the natural history of MS is varying from a benign condition to a devastating and rapidly incapacitating disease. Clinical heterogeneity could also be cellular and / or molecular. The aim is to identify from OMIC analyses, at the early stage of the disease, differentially expressed molecules and / or cell subpopulations derived from CD8 + T lymphocytes and / or CD4 + T lymphocytes and / or B lymphocytes and monocytes from patients with aggressive versus non-aggressive, compared to a cohort of healthy controls
