CRL4泛素连接酶与分子胶水
仓勇团队的研究建立在20年来对Cullin Ring Ligase 4 (CRL4)泛素连接酶(特别是CRL4CRBN)的专业知识基础上。他们设计了靶向CRBN的化合物库,并筛选出能够降解癌症驱动蛋白的新型分子胶水,为现有肿瘤药物研发提供了新模式。同时,研究揭示了来那度胺及其类似物作为分子胶水劫持CRBN发挥临床疗效的机制。
免疫治疗机制
研究发现来那度胺可以通过激活Notch信号绕过CD28共刺激,恢复PD-1免疫治疗的效果(Cell Chemical Biology, 2022)。此外,利用CRISPR-Cas9文库筛选,鉴定出多个通过调节肿瘤浸润淋巴细胞来影响肿瘤生长的通路,其中一些依赖PD-1免疫检查点,另一些则不依赖。
肿瘤免疫逃逸
在肝细胞癌研究中,SGK1的缺失通过促进T细胞介导的免疫抵抗支持转移定植(Journal of Hepatology, 2025)。另外,肿瘤进化选择性失活核心microRNA机制以逃避免疫监视(Nature Communications, 2021)。
