I. Background | |
T 細(xì)胞在細(xì)胞介導(dǎo)的免疫中發(fā)揮核心作用,可以介導(dǎo)長期、抗原特異性、效應(yīng)和記憶 反應(yīng)。T 細(xì)胞是許多免疫療法的靶標(biāo),包括檢查點抑制劑、雙特異性 T 細(xì)胞接合器和免疫 激動劑。此外,T 細(xì)胞本身已被研究為血液系統(tǒng)惡性腫瘤中使用嵌合抗原受體添加或自體 過繼轉(zhuǎn)移的療法。近年來,各種旨在誘導(dǎo)、增強(qiáng)和/或工程化 T 細(xì)胞反應(yīng)的免疫治療策略已 成為治療癌癥和自身免疫等疾病的有希望的方法。 T 細(xì)胞受體(T cell receptor,TCR)是 T 細(xì)胞特異性識別和結(jié)合抗原肽-MHC 分子的分 子結(jié)構(gòu), 其介導(dǎo)的 T 細(xì)胞活化在胸腺 T 細(xì)胞發(fā)育,T 細(xì)胞亞群分化以及效應(yīng) T 細(xì)胞功能發(fā) 揮過程中均起著至關(guān)重要的作用。TCR 能特異性識別抗原提呈細(xì)胞表面 MHC 提呈的抗原 肽(peptide),并將胞外識別轉(zhuǎn)化為可向細(xì)胞內(nèi)部傳遞的信號,通過誘導(dǎo) TCR 鄰近酪氨酸 激酶活化,促進(jìn)信號傳遞復(fù)合物組裝,活化下游 MAPK、PKC 以及鈣離子等信號途徑,最 終活化相應(yīng)的轉(zhuǎn)錄因子,調(diào)控效應(yīng)蛋白分子的表達(dá),完成 T 細(xì)胞的活化。 |
