CTSB
組織蛋白酶B（Cathepsin B）是一種溶酶體半胱氨酸蛋白酶，常被簡稱為CathB或CTSB。這種酶在正常生理狀態下負責降解受損蛋白質，維持細胞穩態，但在病理條件下可能促進腫瘤侵襲與炎癥反應。研究發現，其過度激活會破壞細胞外基質，加速癌細胞穿透血管壁形成轉移灶，在乳腺癌、膠質瘤等多種惡性腫瘤中呈現高表達特征。此外，該蛋白酶還參與阿爾茨海默病的β淀粉樣蛋白沉積過程，并能激活炎癥小體加重類風濕性關節炎。
近年來針對CTSB的藥物開發聚焦于特異性抑制劑，例如CA-074系列化合物已顯示出阻斷腫瘤轉移的潛力。部分研究嘗試將CTSB抑制劑與免疫檢查點療法聯用，通過調控腫瘤微環境增強抗PD-1治療效果。在神經退行性疾病領域，小分子抑制劑Esteya表現出抑制tau蛋白異常磷酸化的作用，目前處于臨床前研究階段。值得注意的是，新冠病毒感染研究中發現CTSB可能參與病毒刺突蛋白的切割激活，這為抗病毒藥物研發提供了新思路。
