The Bar-Or laboratory recently reported that human B cells from normal subjects can produce either pro-inflammatory (TNF-alpha; LT) or regulatory (IL-10) effector cytokines depending on their context of activation. It was of interest to investigate the change in B cell cytokine profiles from normal subjects when activated in the context of a Th1 pro-inflammatory environment or a Th2 anti-inflammatory environment. It was found that the B cell regulatory network of effector cytokines from normal subjects is significantly modulated depending on the local cytokine milieu. In addition, it was of interest to study how MS patients' B cell cytokine network would respond in a Th1 pro-inflammatory and a Th2 anti-inflammatory context. It was found that MS patients' B cell cytokine network was dysregulated compared to B cell responses from normal subjects. The findings define a novel regulatory network involving human B cells from normal subjects and point to a newly discovered abnormality in MS patients' B cells.
