研發(fā)背景:
8D3單克隆抗體可識別小鼠CD71蛋白,也被稱為轉(zhuǎn)鐵蛋白受體抗體1(TfR1)。CD71是分子量大小為170-180kDa的II型同型二聚跨膜糖蛋白,該蛋白表達(dá)于增殖細(xì)胞、網(wǎng)狀細(xì)胞和類紅細(xì)胞前體等細(xì)胞的表面。
?
有研究表明,CD71在調(diào)節(jié)細(xì)胞增殖的過程中發(fā)揮作用。另外,CD71還通過內(nèi)吞作用協(xié)助運鐵蛋白將鐵轉(zhuǎn)運到胞內(nèi)。 CD71在惡性腫瘤細(xì)胞上大量表達(dá),其表達(dá)量與癌癥的進(jìn)展、進(jìn)程相關(guān)。由于CD71在惡性腫瘤細(xì)胞上的高表達(dá)產(chǎn)生的細(xì)胞內(nèi)化能力以及鐵對癌細(xì)胞增殖的必要性使轉(zhuǎn)鐵蛋白受體(TfR1)成為將藥物輸送到惡性細(xì)胞中的關(guān)鍵靶標(biāo)以及研究熱點。相關(guān)研究結(jié)果顯示8D3抗體可在體內(nèi)消耗CD71 +細(xì)胞。
