Abstract
IL-10 is the best known and most studied anti-inflammatory cytokine and, in the last 20 years, it has acquired even greater fame as it has been associated with the regulatory phenotype of B cells. Indeed, although great efforts have been made to find a unique marker, to date IL-10 remains the main way to follow both murine and human regulatory B cells, hence the need of precise and reproducible methods to identify and purify IL-10-producing B cells for both functional and molecular downstream assays. In this chapter, we present our protocols to isolate these cells from the murine spleen and peritoneum and from human peripheral blood. Since the production of IL-10 by B cells is not only a weapon to counteract the adverse effect of pro-inflammatory cytokines but also a response to cellular activation, we focused on those B cells that are prone to IL-10 production and detectable following a short-term stimulation with phorbol-12-myristate-13-acetate, ionomycin, and lipopolysaccharide (murine system) or CpG (human system).
