  • 最新研究进展：
    MBL2是一种结合型支链蛋白，全名为结合型支链蛋白2。它主要参与免疫调节和细胞凋亡等生理过程，同时还参与了多种疾病的发生和发展，如感染、肝脏疾病等。最近的研究表明，MBL2基因的多态性与自身免疫性疾病、感染性疾病等的发生风险相关。
  • 功能：
    Calcium-dependent lectin involved in innate immune defense. Binds mannose, fucose and N-acetylglucosamine on different microorganisms and activates the lectin complement pathway. Binds to late apoptotic cells, as well as to apoptotic blebs and to necrotic cells, but not to early apoptotic cells, facilitating their uptake by macrophages. May bind DNA.
