ITGAL
ITGAL對應的蛋白全稱為整合素αL，也被稱為CD11a或LFA-1α，常與β2亞基結合形成淋巴細胞功能相關抗原-1（LFA-1）。這種蛋白在免疫細胞表面廣泛表達，尤其在T細胞和中性粒細胞中活躍，通過介導細胞間黏附參與炎癥反應、免疫細胞遷移及抗原提呈等過程。其功能異常常與自身免疫疾病相關，例如多發性硬化癥、類風濕性關節炎患者的LFA-1活性異常升高，導致免疫細胞過度攻擊自身組織。此外，該蛋白在器官移植排斥反應和某些白血病中也顯示出調控作用。
近年來，針對LFA-1的抑制劑成為藥物開發熱點。早期單抗藥物如奧法木單抗曾用于治療復發型多發性硬化，但因療效局限逐漸淡出。小分子拮抗劑如BMS-817399在動物模型中顯示出抑制炎癥浸潤潛力，目前處于臨床前研究階段。部分藥物因阻斷LFA-1可能引發感染風險，研究者正探索局部給藥或變構調節策略以平衡療效與安全性。在腫瘤免疫領域，聯合LFA-1調控與其他免疫檢查點抑制劑的方案也進入早期探索。
