BTLA

BTLA,即B和T淋巴細胞弱化因子,別名BTNL9、BTLA。它是一種主要在T細胞、B細胞和NK細胞上表達的免疫檢查點分子,由人體細胞自身的基因編碼。BTLA的作用機制涉及與其特異性配體HVEM(皰疹病毒入侵介質)結合,這種結合能夠抑制T細胞和B細胞的活化、增殖以及細胞因子的生成。BTLA與HVEM的結合通過激活免疫受體酪氨酸的抑制基序(ITIM)和免疫球蛋白酪氨酸開關基序(ITSM),導致SHP-1和SHP-2的磷酸化和募集,從而抑制T細胞的增殖和IL-2的產生,產生免疫抑制效應 。BTLA參與了多種生理和病理過程的調節,包括腫瘤、炎癥性疾病、自身免疫性疾病等。在腫瘤微環境中,BTLA的激活是PD-1抗體的潛在耐藥機制之一,BTLA的表達與腫瘤的進展密切相關。在炎癥性疾病中,BTLA對T細胞介導的炎癥具有負調節作用。此外,在自身免疫性疾病中,BTLA的表達水平與疾病的活動性相關。因此,BTLA是免疫學研究和相關疾病治療中的一個潛在靶點 。
