I. Background | |
BAFF(B 細(xì)胞激活因子,B Cell Activating Factor),也稱為 TNFSF13B(Tumor Necrosis Factor Superfamily Member 13B)或 BLyS(B Lymphocyte Stimulator),是一種屬 于腫瘤壞死因子(TNF)超家族的細(xì)胞因子。BAFF 主要由單核細(xì)胞、巨噬細(xì)胞、樹突狀 細(xì)胞和某些基質(zhì)細(xì)胞產(chǎn)生,在 B 細(xì)胞的存活、增殖和成熟中起關(guān)鍵作用。 BAFF 通過與受體結(jié)合,調(diào)節(jié) B 細(xì)胞的發(fā)育和功能,其過度表達(dá)與自身免疫性疾病 (如系統(tǒng)性紅斑狼瘡、類風(fēng)濕性關(guān)節(jié)炎)密切相關(guān)。BAFF 有三個(gè)主要受體:BAFF-R (BR3)、TACI 和 BCMA。BAFF 與 BAFF-R 結(jié)合后,激活 NF-κB 和 PI3K/AKT 通路,促 進(jìn) B 細(xì)胞的存活和增殖;TACI 介導(dǎo) BAFF 和 APRIL(另一種 TNF 家族成員)的信號(hào)傳導(dǎo), 調(diào)節(jié) B 細(xì)胞的活化和抗體產(chǎn)生;BCMA 主要在漿細(xì)胞中表達(dá),介導(dǎo) BAFF 和 APRIL 的信 號(hào)傳導(dǎo),支持漿細(xì)胞的存活。BAFF 的過度表達(dá)與系統(tǒng)性紅斑狼瘡(SLE)、類風(fēng)濕性關(guān)節(jié) 炎(RA)、干燥綜合等自身免疫性疾病密切相關(guān)。 |
