| I. Background | |
| PD-1(程序性死亡受體 1),T 細胞表面的一種免疫檢查點受體,通常用于抑制 T 細 胞過度活躍,但癌細胞會利用它來逃避攻擊,導致 T 細胞“耗竭”。而 IL-2 作為 T 細胞增 殖與存活的關鍵細胞因子,可擴增效應 T 細胞(Teff)及自然殺傷細胞(NK),但傳統(tǒng) IL -2 同時激活調節(jié)性 T 細胞(Treg),可能削弱免疫應答。 將 PD-1 檢查點阻斷與 IL-2 對 T 細胞的增強作用相結合,從而創(chuàng)造出能夠“喚醒”腫 瘤內耗竭 T 細胞的療法,以實現(xiàn)更強、更精準的抗癌反應,且潛在毒性可能低于單獨使用這兩種物質。這些分子能夠將 IL-2 直接遞送至表達 PD-1 的腫瘤浸潤淋巴細胞(TILs), 增強其殺傷癌細胞的能力。 |
