BCAP 最近被克隆为磷酸肌醇 3-激酶 (PI3K) 的结合分子。为了研究 BCAP 的作用,产生了 BCAP 缺陷的突变小鼠。虽然 BCAP 缺陷小鼠能够存活,但它们的成熟 B 细胞数量减少,且 B1 B 细胞缺乏。小鼠产生的血清免疫球蛋白 (Ig)M 和 IgG3 滴度较低,并且对不依赖于 T 细胞的 II 型抗原的反应减弱。 B 细胞受体交联后,BCAP 缺陷的 B 细胞表现出 Ca2+ 动员减少和增殖反应较差。这些发现表明 BCAP 在 B 细胞发育和体液免疫反应中发挥着关键的免疫调节作用。
BCAP was recently cloned as a binding molecule to phosphoinositide 3-kinase (PI3K). To investigate the role of BCAP, mutant mice deficient in BCAP were generated. While BCAP-deficient mice are viable, they have decreased numbers of mature B cells and B1 B cell deficiency. The mice produce lower titers of serum immunoglobulin (Ig)M and IgG3, and mount attenuated responses to T cell–independent type II antigen. Upon B cell receptor cross-linking, BCAP-deficient B cells exhibit reduced Ca2+ mobilization and poor proliferative responses. These findings demonstrate that BCAP plays a pivotal immunoregulatory role in B cell development and humoral immune responses.
