| I. Background | |
| ICOS 是一種在 T 細(xì)胞活化后才被誘導(dǎo)表達(dá)的共刺激受體，而 ICOSL 是其配體，主要 組成性表達(dá)于 B 細(xì)胞和抗原呈遞細(xì)胞表面。兩者的核心作用機(jī)理在于，當(dāng)活化的 T 細(xì)胞 （特別是濾泡輔助性 T 細(xì)胞）遷移至淋巴濾泡并與 B 細(xì)胞相遇時，ICOS 與 ICOSL 的結(jié)合 為 T 細(xì)胞提供了關(guān)鍵的共刺激信號，這主要通過激活 PI3K 等下游通路，驅(qū)動 T 細(xì)胞增殖、 存活及產(chǎn)生細(xì)胞因子（如 IL-21），從而精確調(diào)控生發(fā)中心反應(yīng)，最終促進(jìn) B 細(xì)胞進(jìn)行抗 體親和力成熟與類別轉(zhuǎn)換，產(chǎn)生高效體液免疫。 | |
