TNFRSF14

皰疹病毒進(jìn)入介體(Herpes virus entry mediator A,HVEM,又稱TNFRSF14)是TNF受體超家族成員,廣泛表達(dá)于APCs、內(nèi)皮細(xì)胞和淋巴細(xì)胞,尤其是幼稚T細(xì)胞。HVEM與多種蛋白結(jié)合,包括LIGHT、TNF-β、BTLA和CD160。當(dāng)HVEM與LIGHT或LTα結(jié)合時(shí),傳遞共刺激信號(hào),而HVEM與BTLA或CD160結(jié)合則觸發(fā)共抑制信號(hào)。因此,HVEM通常被描述為取決于所接合配體的分子開關(guān)。研究發(fā)現(xiàn),HVEM在一些腫瘤中過表達(dá),并且顯示腫瘤浸潤T細(xì)胞呈BTLA陽性。此外,HVEM的高表達(dá)與顯著較差的預(yù)后相關(guān)。腫瘤中HVEM上調(diào)代表了一種免疫逃逸機(jī)制,類似于腫瘤細(xì)胞過度表達(dá)PD-L1或PD-L2。根據(jù)轉(zhuǎn)錄組學(xué)分析,HVEM表達(dá)與免疫細(xì)胞浸潤和微環(huán)境中的基質(zhì)細(xì)胞有關(guān)。HVEM的表達(dá)還與PD-1、PD-L1、CTLA-4、LAG-3和VISTA的表達(dá)相關(guān)。因此,HVEM在免疫和炎癥反應(yīng)的調(diào)節(jié)中起著至關(guān)重要的作用,尤其是T細(xì)胞的激活。
