Abstract
在眾多免疫治療方法中,免疫檢查點抑制劑 (ICBs) 在臨床上具有最好的效 果,使其在臨床上成為最有潛力的治療方式,各大藥廠也不斷地往這塊領域發展, 研發出更多更有效用的抑制劑。但在進入臨床使用前,評估新藥之安全性及藥效 的體內藥物篩選測試是非常重要的。本實驗以同軸靜電紡絲製備聚乳酸之微管陣 列薄膜 (MTAM) 作為基材,將癌細胞與小鼠體內免疫細胞共培養於MTAM管腔 內,植入老鼠皮下後並給予抗癌免疫檢查點抑制劑 (Anti-pd-1),進行細胞活性試 驗以及小鼠皮下血管新生分析。體外實驗結果顯示,活化之T細胞被Anti-pd-1激 活後,可有效抑制癌細胞生長,癌細胞活性抑制約70%,細胞毒殺能力提升約82%。 動物模型篩選實驗結果顯示,植入裸鼠與一般小鼠皮下管腔內癌細胞生長曲線和 皮下血管新生生長曲線兩者皆相同,偵測來自MTAM膜外免疫細胞分泌γ干擾素 總量極低。此證明,HFA-MTAM可選用具有免疫系統且低成本之一般小鼠作為 動物模型。HFA-MTAM之體內實驗結果顯示,活化之T細胞被Anti-pd-1激活後, 癌細胞活性抑制約50%,證明此方法可在動物體內執行。綜合上述說明,HFA- MTAM可應用在抗癌ICBs藥物體內篩選平台。
