Brief summary

The purpose of this study is to investigate the immune cell and other factor changes with Ocrevus in Multiple Sclerosis (MS) patients. Researchers will recruit 35 participants for this study. Patients will be enrolled from the Multiple Sclerosis Center at the University of Michigan Health System in Ann Arbor. The goal of the study is to understand the role of regulatory B cell, T cell and other factors in mediating the therapeutic effects of Ocrevus.
