A transcription factor nuclear factor-kappaB (NF-kappaB) plays an essential role in the overall regulation of the immune system and inflammatory responses. Activation of NF-kappaB is tightly regulated by inhibitory proteins termed IkappaB, which consist of classical cytoplasmic and nuclear IkappaBs. Roles of a nuclear regulator of NF-kappaB, IkappaBNS, in the development and function of B cells were studied. We have found that IkappaBNS is important for proliferative activity and antibody production via Toll-like receptor signals. IkappaBNS is also involved in the development of regulatory B cells that produce anti-inflammatory cytokine IL-10. Thus, an additional important role for IkappaBNS in control of the immune response was defined.

转录因子核因子-kappaB（NF-kappaB）在免疫系统和炎症反应的整体调节中起重要作用。NF-κ B的激活受称为IkappaB的抑制性蛋白的严格调节，IkappaB由经典的细胞质和细胞核IkappaB组成。研究了NF-κ B B的核调节因子IkappaBNS在B细胞发育和功能中的作用。我们已经发现，IkappaBNS是重要的增殖活性和抗体生产通过Toll样受体信号。IkappaBNS还参与产生抗炎细胞因子IL-10的调节性B细胞的发育。因此，定义了IkappaBNS在控制免疫应答中的额外重要作用。
