| I. Background | |
| PD-1(程序性死亡受體 1),T 細(xì)胞表面的一種免疫檢查點(diǎn)受體,通常用于抑制 T 細(xì) 胞過(guò)度活躍,但癌細(xì)胞會(huì)利用它來(lái)逃避攻擊,導(dǎo)致 T 細(xì)胞“耗竭”。而 IL-2 作為 T 細(xì)胞增 殖與存活的關(guān)鍵細(xì)胞因子,可擴(kuò)增效應(yīng) T 細(xì)胞(Teff)及自然殺傷細(xì)胞(NK),但傳統(tǒng) IL -2 同時(shí)激活調(diào)節(jié)性 T 細(xì)胞(Treg),可能削弱免疫應(yīng)答。 將 PD-1 檢查點(diǎn)阻斷與 IL-2 對(duì) T 細(xì)胞的增強(qiáng)作用相結(jié)合,從而創(chuàng)造出能夠“喚醒”腫 瘤內(nèi)耗竭 T 細(xì)胞的療法,以實(shí)現(xiàn)更強(qiáng)、更精準(zhǔn)的抗癌反應(yīng),且潛在毒性可能低于單獨(dú)使用 這兩種物質(zhì)。這些分子能夠?qū)?IL-2 直接遞送至表達(dá) PD-1 的腫瘤浸潤(rùn)淋巴細(xì)胞(TILs), 增強(qiáng)其殺傷癌細(xì)胞的能力。 |
