1331-光驱动热敏水凝胶:精准脂质干预与术后肿瘤复发防治

from 聊聊Sci

研究人员开发了一种名为 LTG@RL 的新型光驱动热致变色水凝胶,旨在解决恶性肿瘤手术后的复发难题。该系统通过封装载有脂肪氧化酶 (LOX) 和雷帕霉素 (Ra) 的纳米调制剂,利用术后切口处丰富的脂肪酸作为治疗靶点。在近红外光照射下,水凝胶发生可逆的液化切换,使其能深入渗透复杂的伤口空隙并提供持久的药物释放。这种协调的脂质干预策略不仅能诱导残留癌细胞发生铁死亡,还能通过调节脂质代谢将肿瘤相关巨噬细胞从促癌的 M2 型重塑为抗肿瘤的 M1 型。实验证明,该策略在黑色素瘤和乳腺癌模型中均显著抑制了肿瘤复发,并有效激活了机体的免疫监视能力。 References: Zhong Z, Gan L, Gao Y, et al.
