BTN2A2
Butyrophilin亞科成員2A2（BTN2A2）是一種調控免疫穩態的關鍵蛋白，也被稱為CD277或嗜乳脂蛋白樣分子。它與γδ T細胞表面受體相互作用，通過調節這類特殊免疫細胞的活化閾值，維持機體對病原體和異常細胞的有效防御。BTN2A2在腫瘤微環境中呈現異常表達模式，其表達水平變化可能影響癌細胞免疫逃逸能力，尤其在乳腺癌、卵巢癌中顯示出與患者預后的相關性。
在病理機制方面，BTN2A2基因區域的遺傳變異與系統性紅斑狼瘡、1型糖尿病等自身免疫疾病易感性顯著相關。基于其獨特的免疫檢查點特性，多家生物技術公司正開發靶向該蛋白的雙特異性抗體，其中AB-102項目已完成臨床前研究，通過同時阻斷BTN2A2和PD-1信號軸，旨在增強T細胞對實體瘤的殺傷效果。BTN2A2蛋白在神經退行性疾病中的潛在作用也引發關注，阿爾茨海默病患者腦脊液中檢測到其特異性異構體異常升高，相關機制仍在深入解析中。
