B cells shape the alloimmune response through polarized subsets. These cells inhibit or promote immune responses by expressing suppressive or proinflammatory cytokines. Their summed activity dictates the influence of B cells on the alloimmune response. We review the evidence for regulatory B cells and effector B cells in mice and humans, discuss current limitations in their phenotypic identification, and discuss regulatory B cells as a signature for clinical renal allograft tolerance and predictive markers for allograft outcomes. We discuss the effects of therapeutic agents on regulatory B cells and potential approaches to augment their numbers as a therapeutic tool.
B细胞通过极化亚群塑造同种免疫反应。这些细胞通过表达抑制性或促炎细胞因子来抑制或促进免疫反应。它们的总体活性决定了B细胞对同种免疫反应的影响。我们综述了小鼠和人类中调节性B细胞和效应B细胞的证据，讨论了它们在表型鉴定方面目前存在的局限性，并讨论了调节性B细胞作为临床肾移植耐受性的标志以及移植结果的预测标志物。我们还讨论了治疗药物对调节性B细胞的影响以及增加其数量作为一种治疗工具的潜在方法。
