How B-cells Work to Promote MS and T-cell Attacks on Myelin Detailed in Study

B-cells in the immune system play an important role in the unfolding of inflammation and brain lesions in multiple sclerosis (MS), largely by how they influence the actions of another immune system cell, called T-cells, a new study reports.

Its findings help explain why therapies like Ocrevus and off-label use of rituximab, both of which act on B-cells, are effective in controlling MS.

The study, “Memory B Cells Activate Brain-Homing, Autoreactive CD4+ T Cells in Multiple Sclerosis,” was published in the journal Cell.

Despite advances in understanding MS, it is still unclear exactly which specific cells and molecules drive the immune system to attack healthy tissue and damage the protective myelin layer surrounding nerve cells in the brain and spinal cord.

A team of researchers at the University of Zurich and the Karolinska Institute in Sweden report that memory B-cells, so-called because they normally work to remind the immune system of
