683. 他汀类药物助力攻克癌症免疫逃逸

from 知为谁 · host 知为谁

这项由日本藤田医科大学领导的研究揭示了癌症逃避免疫治疗的一种隐蔽机制。科学家发现,肿瘤细胞会利用一种名为 UBL3 的蛋白质,将具有免疫抑制功能的 PD-L1 蛋白包装进微小的细胞外囊泡中,并将其释放到全身以削弱免疫系统的攻击。关键发现在于,临床上常用的降胆固醇药物——他汀类药物,能够有效阻断这一包装过程,从而减少血液中抑制性囊泡的含量。这一发现解释了为何许多患者对免疫检查点抑制剂反应不佳,并为提高治疗效果提供了新途径。通过将他汀类药物与现有的免疫疗法相结合,医生未来可能以更低廉且安全的方式增强抗癌成效。该研究不仅确定了癌症免疫逃逸的新靶点,也为改善肺癌等患者的生存率带来了新希望。内容来源:https://www.sciencedaily.com/releases/2026/01/260128075323.htm
