HHLA2
HHLA2，全名為HERV-H LTR-associating protein 2，常見別名包括B7-H7、B7H7和HHLA2。該蛋白主要表達于人類單核細胞表面，并可在B細胞上誘導表達。HHLA2與T淋巴細胞表面的受體結合，抑制T細胞的增殖，從而調節細胞介導的免疫反應。近年來，HHLA2被發現與多種腫瘤細胞的免疫逃逸密切相關，成為腫瘤免疫治療的重要靶點。和鉑醫藥研發的全人源單克隆抗體HBM1020，正是靶向B7H7/HHLA2的創新療法，為PD-(L)1抑制劑治療無效的患者提供了新的治療選擇。此外，HHLA2還與自身免疫性疾病的發生發展有關，其在疾病中的具體作用機制和臨床應用仍需進一步研究。
