背景(Background)
ICOS配體(ICOSLG)也稱為B7同源物2(B7-H2)、B7相關蛋白1(B7RP-1)和CD抗原CD275,屬于免疫球蛋白超家族和BTN/MOG家族。ICOSLG包含一個Ig-like C2型(免疫球蛋白樣)結構域和一個Ig-like V型(免疫蛋白樣)功能域。異構體1廣泛表達,而異構體2僅在淋巴結、白細胞和脾臟中檢測到。B7-H2是T細胞特異性細胞表面受體ICOS的配體。B7-H2作為T細胞增殖和細胞因子分泌的共刺激信號,也誘導B細胞增殖和分化為漿細胞。B7-H2可能在介導局部組織對炎癥條件的反應以及通過共刺激記憶T細胞功能調節(jié)二次免疫反應中發(fā)揮重要作用。
