1340-SOAT1抑制：肝癌免疫逃逸与复发的关键靶点

这组研究揭示了SOAT1酶在肝细胞癌（HCC）免疫逃逸与术后复发中的核心驱动作用。通过对临床样本的蛋白组学分析，研究者发现SOAT1高表达与患者预后不良及免疫治疗耐药显著相关。在机制上，抑制该酶会增加内质网胆固醇含量，进而干扰SREBP代谢通路，削弱肿瘤细胞在免疫攻击下的氧化还原韧性。实验证明，利用药物或基因手段靶向SOAT1能显著增强CD8+ T细胞的杀伤效率，并提升PD-1抑制剂与CAR-T疗法的抗肿瘤效果。该研究为预防肝癌复发和优化肥胖相关肿瘤的免疫治疗提供了关键的代谢新靶点。References:Gu Y, Zhang L, Li J, et al.
