Regulatory B cells (Bregs) suppress immune response via the provision of IL-10. Due to the phenotypic heterogeneity of described Bregs, it is important to have standardized protocols for their isolation and identification. Previous work by our laboratory has shown that the immature B-cell populations in the murine spleen and human peripheral blood produce the highest levels of IL-10 on engagement of CD40, and can suppress pro-inflammatory T-cell differentiation. In this chapter, we describe the methods necessary for the isolation of this subset of Bregs and their activation via CD40 in vitro.
