Dissection of multiple sclerosis genetics identifies B and CD4+ T cells as driver cell subsets.

Background: Multiple sclerosis (MS) is an autoimmune condition of the central nervous system with a well-characterized genetic background. Prior analyses of MS genetics have identified broad enrichments across peripheral immune cells, yet the driver immune subsets are unclear.

Results: We utilize chromatin accessibility data across hematopoietic cells to identify cell type-specific enrichments of MS genetic signals.
