FCGR2A
FCGR2A蛋白全稱為免疫球蛋白G Fc段受體IIa，又稱CD32a，是白細胞表面一類關(guān)鍵受體，負責識別抗體標記的病原體或異常細胞。該蛋白主要分布于巨噬細胞、中性粒細胞等免疫細胞，通過結(jié)合IgG抗體的Fc段觸發(fā)吞噬清除或炎癥介質(zhì)釋放，在抗感染和自身免疫平衡中扮演雙重角色。其遺傳多態(tài)性與系統(tǒng)性紅斑狼瘡、類風濕關(guān)節(jié)炎等自身免疫疾病易感性顯著相關(guān)，某些變異體還影響患者對肺炎鏈球菌等病原體的清除能力。
近年來針對FCGR2A的治療策略呈現(xiàn)兩極分化：單抗藥物如替雷利珠單抗通過增強受體激活強化腫瘤免疫應(yīng)答，而Fc工程化改造的抗體片段（如VIB9600）則選擇性抑制受體功能以緩解自身免疫反應(yīng)。2023年進入Ⅱ期臨床試驗的拮抗劑CPI-006顯示出調(diào)控新冠重癥患者細胞因子風暴的潛力。該受體還被用于設(shè)計雙特異性抗體支架，旨在提高CAR-T細胞對實體瘤的識別效率，相關(guān)研究尚處于臨床前階段。
