Description
DR是糖尿病常見且具致盲風險的併發症,其病程與高血糖誘導的組織損傷、氧化壓力及發炎反應密切相關。研究顯示RPE細胞功能障礙是DR進展的關鍵,而細胞內脂質小滴的異常堆積在此過程中扮演重要角色。已知GLP-1 RA在調控代謝疾病中展現多重效應,包括改善脂質代謝、減少氧化壓力及促進細胞自噬,然而其對DR的影響仍存爭議。近期研究指出,外泌體作為細胞間訊息傳遞的關鍵媒介,在調控代謝穩態及抗炎反應中具有潛力,因此本計畫將特別著重於GLP-1 RA對視網膜細胞的雙向效應,並引入外泌體研究,評估GLP-1 RA對RPE細胞分泌的外泌體內容物及其功能的影響,進一步探索外泌體在減少脂質堆積及改善氧化壓力中的可能作用,期望為DR的分子機制及治療策略提供新的見解。
