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.
调节性B细胞(Bregs)通过分泌白细胞介素-10(IL-10)来抑制免疫反应。由于所描述的Bregs存在表型异质性,因此制定标准化的分离和鉴定方案非常重要。我们实验室之前的工作表明,小鼠脾脏和人类外周血中的未成熟B细胞群体在CD40激活时产生的IL-10水平最高,并且能够抑制促炎性T细胞分化。在本章中,我们描述了分离该Bregs亚群并在体外通过CD40激活它们所需的方法。
