背景(Background)
B細(xì)胞活化因子(BAFF)也稱為腫瘤壞死因子配體超家族成員13B、TNFSF13B、BAFF、B淋巴細(xì)胞刺激因子(BLyS)、分化簇257(CD257)、DTL、TNF-和APOL相關(guān)白細(xì)胞表達(dá)配體(TALL-1)、THANK、TNFSF20、ZTNF4,是一種屬于腫瘤壞死因子(TNF)配體家族的細(xì)胞因子。這種細(xì)胞因子是受體TNFRSF13B/TACI、TNFRSF17/BCMA和TNFRSF13C/BAFFR的配體。這種細(xì)胞因子在B細(xì)胞譜系細(xì)胞中表達(dá),并作為一種強(qiáng)效的B細(xì)胞激活劑。它也被證明在B細(xì)胞的增殖和分化中起著重要作用。它在各種細(xì)胞類型上表達(dá)為跨膜蛋白,包括單核細(xì)胞、樹突狀細(xì)胞和骨髓基質(zhì)細(xì)胞。BAFF是三種不尋常的腫瘤壞死因子受體BAFF-R、TACI和BCMA的天然配體,所有這些受體對BAFF都有不同的結(jié)合親和力。這些受體主要在成熟的B淋巴細(xì)胞上表達(dá)(TACI也存在于T細(xì)胞的一個(gè)子集上,BCMA存在于漿細(xì)胞上)。TACI結(jié)合最差,因?yàn)樗鼘σ环N類似于BAFF的蛋白質(zhì)的親和力更高,這種蛋白質(zhì)被稱為增殖誘導(dǎo)配體(APRIL)。BCMA顯示出中間結(jié)合表型,并將在不同程度上與BAFF或APRIL一起使用。通過BAFF-R和BCMA的信號傳導(dǎo)刺激B淋巴細(xì)胞進(jìn)行增殖和抗凋亡。所有這些配體都充當(dāng)與異三聚體受體相互作用的異三聚體(即同一分子的三個(gè)),盡管已知BAFF作為異三聚體或同源三聚體具有活性。BAFF作為一種強(qiáng)效的B細(xì)胞激活劑,已被證明在B細(xì)胞的增殖和分化中起著重要作用。
