CD79B
CD79B，即B細胞受體信號轉導亞單位β，別名包括Igβ、B29、CD79b等。它是一種B細胞受體(BCR)的組成部分，由CD79B基因編碼，主要在B細胞表面表達。CD79B與CD79A(Igα)形成異源二聚體，參與BCR介導的信號轉導過程，對B細胞的活化、增殖和分化具有重要作用 。CD79B的作用機制主要是通過與BCR復合物中的mIgM或mIgD結合，轉導抗原識別后的信號。當BCR識別并結合抗原后，CD79B能夠激活Src家族激酶，如Lyn，進而激活下游的Syk和Btk等酪氨酸激酶，觸發信號級聯反應。這些信號通路包括MAPK、PI3K/Akt等，最終導致細胞內鈣離子的釋放、細胞增殖和分化等生物學效應 。在生物學意義上，CD79B在B細胞發育、成熟和功能中發揮關鍵作用。它不僅參與B細胞受體介導的信號傳導，還可能參與調節B細胞的存活和凋亡。此外，CD79B在多種B細胞來源的惡性腫瘤中高度表達，如彌漫性大B細胞淋巴瘤(DLBCL)，使其成為治療某些B細胞惡性腫瘤的潛在靶點。已有針對CD79B的抗體偶聯藥物(ADC)，如Polatuzumab vedotin，被開發用于治療某些類型的非霍奇金淋巴瘤(NHL) 。
