I. Background | |
腫瘤細胞可以借助免疫檢查點受體逃避機體免疫系統的識別和殺傷,因此阻斷免疫檢 查點受體可能是一種廣泛有效的治療方法。目前,抗 PD-1/PD-L1 抗體雖然比較 成熟,與抗 CTLA4 抗體類似,但由于存在耐藥性,患者的總體有效率較低,因此尋找新 的治療靶點迫在眉睫。 Programmed Cell Death Protein 1 (PD-1),一種在激活的 T 細胞上表達的受體,與其配 體 PD-L1 和 PD-L2 結合,負向調節免疫反應。 PD-1 配體存在于大多數癌癥中,PD-1:PD- L1/2 相互作用會抑制 T 細胞活性,并使癌細胞逃避免疫監視。 PD1/PDL1 信號轉導通路是 腫瘤免疫抑制的重要組成部分,可以抑制 T 淋巴細胞的興奮,增強腫瘤細胞的免疫耐受, 從而實現腫瘤免疫逃逸。PD1 與 PDL1 結合可以減弱 T 細胞介導的免疫監視,導致免疫反 應缺失,甚至導致 T 細胞凋亡。PD1/PDL1 抑制劑可解除抗腫瘤 T 細胞的免疫抑制,從而 導致 T 細胞增殖并滲透到腫瘤微環境中并誘導抗腫瘤反應。PD-1:PD-L1/2 通路還參與調節 自身免疫反應,使這些蛋白質成為多種癌癥以及多發性硬化癥、關節炎、狼瘡和 I 型糖尿 病的有希望的治療靶點。磷酸酶 SHP2 是 T 細胞功能的關鍵調節因子,它介導 TCR 下游的激活信號以及 PD-1 下游的抑制信號。 | |
