I. Background | |||
免疫調(diào)節(jié)蛋白的 B7 家族是結(jié)構(gòu)相關(guān)的細(xì)胞表面蛋白,在抗原呈遞細(xì)胞/腫瘤細(xì)胞內(nèi)和 腫瘤/免疫細(xì)胞之間的信號(hào)傳導(dǎo)中起著核心作用。B7 家族成員(包括 CTLA-4、PD-1 和 PD-L1)之間的相互作用介導(dǎo)的免疫檢查點(diǎn)機(jī)制可以產(chǎn)生致瘤和共調(diào)節(jié)功能。B7-H3 蛋白 表達(dá)與許多實(shí)體瘤(包括宮頸癌、卵巢癌和乳腺癌等)的不良預(yù)后具有相關(guān)性。B7-H3 (CD276)有兩種異構(gòu)體(2Ig 和 4Ig),沒(méi)有確定的同源受體,B7-H3 在多種惡性腫瘤中 均有表達(dá),與惡性腫瘤的生長(zhǎng)、轉(zhuǎn)移、復(fù)發(fā)、預(yù)后不良等因素密切相關(guān)。B7-H3 可下調(diào)T 輔助 1 型介導(dǎo)的免疫反應(yīng)抑制 CD4+T 細(xì)胞活化,并抑制細(xì)胞因子的產(chǎn)生,發(fā)揮促進(jìn)癌細(xì)胞 免疫逃逸的作用。 | |||
