Abstract
缺氧驅動的血管新生、發炎反應與基質軟化三者交互作用,會侵蝕關節軟骨並削弱現行的骨關節炎(OA)治療效果。本研究提出一種光自養型「微藻機器人」水凝膠—ALG-TYR/CHL/pEV@DIF,該系統將具光合作用的綠藻(Chlorella, CHL)微型反應器、血小板來源的細胞外囊泡(extracellular vesicles, pEVs)以及可被近紅外光(NIR)啟動的雙阿魏酸甲烷(diferuloylmethane, DIF)共嵌入在以兒茶酚交聯的藻酸鹽網絡中。單次660奈米雷射脈衝能誘發以下四種協同作用:(i) 光合作用釋放氧氣、氫氣與生物電信號,有效緩解滑膜缺氧並調節免疫反應;(ii) DIF誘發之光動力效應可選擇性清除過度增生的纖維母細胞;(iii) 酪胺酸(tyrosine)促進的二次交聯反應使水凝膠機械強度倍增(約達80 kPa);(iv) 下調CD31表現,有效抑制異常血管新生與相關疼痛反應。
體外實驗顯示,該複合材料可維持大鼠軟骨細胞的存活,同時將纖維母細胞的存活率降低至30%以下,並成功將LPS刺激的RAW 264.7巨噬細胞由表現CD86⁺的M1型轉化為CD206⁺的M2型,且伴隨腫瘤壞死因子α(TNF-α)明顯下降。
這種「有生命」且具光控制特性的水凝膠整合了光合作用氣體釋放、囊泡介導的氧化還原緩衝、氫氣驅動的免疫調節、抗血管新生訊號傳導,以及可控的光動力療法,同時具備可適應力學環境的支架功能。該平台提供了一種微創且不留疤痕的關節軟骨再生策略,展現了自驅動、光響應型生物材料在治療缺氧性發炎疾病中的巨大潛力。
