FCGR3A

FCGR3A，全稱低親和力免疫球蛋白γ Fc區受體III-A，常見別名為CD16a、FCGR3，是IgG Fc片段的受體，主要表達在自然殺傷細胞、巨噬細胞等免疫細胞表面。該蛋白參與抗體依賴性細胞介導的細胞毒性和病毒感染的抗體依賴性增強，通過與IgG結合激活NK細胞等效應細胞，發揮免疫調節作用。FCGR3A在腫瘤免疫治療中具有重要應用，例如靶向HER2的抗體藥物優化的Fc結構域可增強與FCGR3A的親和力，提高抗體介導的細胞毒殺傷效應。目前，多款靶向FCGR3A的藥物正在研發中，包括單克隆抗體、雙特異性抗體等，用于治療腫瘤、自身免疫性疾病等。例如，再鼎醫藥的馬吉妥昔單抗注射液通過優化Fc結構域，增強對FCGR3A的親和力，提高抗腫瘤療效；信達生物的CD40L抗體IBI355則用于調節免疫細胞活性，治療系統性紅斑狼瘡等疾病。這些進展表明FCGR3A是重要的免疫治療靶點，未來有望開發更多基于該靶點的創新藥物。
