免疫檢查點(diǎn)

Immune Checkpoints

免疫檢查點(diǎn)是免疫激活的調控因子,主要在免疫應答過(guò)程中調節T細胞受體(TCR)的抗原識別。它們在維持免疫穩態(tài)和預防自身免疫方面至關(guān)重要。根據不同的免疫激活作用,免疫檢查點(diǎn)可分為兩種類(lèi)型:共刺激免疫檢查點(diǎn)和共抑制免疫檢查點(diǎn)。共刺激免疫檢查點(diǎn)是指一系列可以進(jìn)一步刺激免疫反應的免疫檢查點(diǎn),如CD28,ICOS和CD137。相反,共抑制免疫檢查點(diǎn)對抑制免疫反應的免疫檢查點(diǎn),如PD1,CTLA-4和VISTA。在有效的抗腫瘤免疫過(guò)程中,T細胞作為核心的執行者,首先被T細胞受體介導的抗原識別信號激活,同時(shí)眾多的共刺激信號和共抑制信號精細調節T細胞反應的強度和質(zhì)量。在生理情況下,共刺激分子與免疫檢查點(diǎn)分子保持平衡,從而最大程度減少對于周?chē)=M織的損傷,維持對自身組織的耐受、避免自身免疫反應。而腫瘤細胞可以通過(guò)此機制,異常上調共抑制分子及其相關(guān)配體,抑制T細胞激活,從而逃避免疫殺傷。
