微卫星稳定型结直肠癌(MSS-CRC)是结直肠癌的主要分子亚型,常伴随有疫浸润不足和免疫逃逸,对现有免疫治疗应答有限。Wnt/β-catenin通路高度激活是其进展与免疫抑制的重要机制,但系统性抑制易引发正常组织毒性。针对这一难题,本研究发现Wnt激活的MSS-CRC细胞巨胞饮增强,并偏好摄取糖基化蛋白;据此构建了由糖基化人血清白蛋白(GHSA)与鼠尾草酸(CA)共组装的纳米药物GHSACA。GHSACA可经巨胞饮选择性进入肿瘤细胞,抑制β-catenin、Cyclin D1和C-Myc等关键分子,阻滞增殖并诱导凋亡。体内实验表明,GHSACA可显著抑制CT26肿瘤生长,增加CD8+ T细胞浸润、减少调节性T细胞,且安全性良好。本研究为MSS-CRC选择性Wnt抑制和免疫增敏提供了新策略。

脊髓损伤(SCI)后的继发性损伤会引发剧烈的神经炎症反应。近年来,泛凋亡作为一种整合焦亡、凋亡和坏死性凋亡的炎症性程序性细胞死亡方式,被认为参与多种中枢神经系统疾病,但其细胞特异性和调控机制尚不明确。本研究通过生物信息学分析发现,SCI后小胶质细胞/巨噬细胞中泛凋亡相关通路显著激活,且与腺苷酸活化蛋白激酶(AMPK)信号通路呈负相关。进一步研究表明,二甲双胍可通过激活AMPK抑制小胶质细胞/巨噬细胞的泛凋亡,减少炎症因子释放,并促进其向抗炎表型转化。动物实验进一步证实,二甲双胍治疗可促进轴突再生、突触重塑及运动功能恢复。本研究揭示了AMPK在小胶质细胞泛凋亡中的重要作用,并为二甲双胍应用于脊髓损伤治疗提供了新的理论依据。
