%0 Journal Article %T Dimethyl fumarate alters B©\cell memory and cytokine production in MS patients %A Kyle A. Martin %A Matthew D. Smith %A Peter A. Calabresi %J Archive of "Annals of Clinical and Translational Neurology". %D 2017 %R 10.1002/acn3.411 %X We evaluated the effect of dimethyl fumarate (DMF) treatment on B©\cell memory and cytokine production in 18 patients with relapsing remitting multiple sclerosis (RRMS) using peripheral blood mononuclear cells obtained prior to and at 6 months post©\DMF initiation. We noted a decline in the absolute B©\cell number with DMF treatment, with a preferential depletion of memory B cells and a concurrent increase in na£¿ve B cells. We noted significant reductions in GM©\CSF, TNF©\¦Á, and IL©\6 producing B cells with DMF treatment. These effects on the B©\cell compartment may underlie the beneficial effects of DMF in RRMS %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5420807/
