癌症药物的发现依赖于临床前研究模型。从药物的发现、作用机制的厘清、给药方法的探索再到安全性管理,实验室工作不可或缺,CTLA-4和PD-1的故事就是最好的例证。但我们都清楚,临床前模型是无法完全反映人体免疫真实情况的。不空谈理论,举两个实例:常用的鼠结直肠癌模型MC38,它的高肿瘤突变负荷(TMB)能够反应...
At the endpoint, flow cytometry was performed to examine treatment-induced effects on immune profiles.Results: In the MC38 model, administration of TFF2-MSA suppressed tumor growth (TGI 38%), the combination of TFF2-MSA and anti-PD-1 had an additive effect and suppressed tumor growth ...

联合CSF-1R抑制剂和溶瘤病毒协同增强PD-1抗体治疗效果的机制研究 在MC38和CT26皮下移植瘤模型中,抑瘤率超过92%,并且分别有82%和43%的小鼠经过治疗后肿瘤完全消退。通过机制研究发现,三者联合治疗诱发了特异的、CD8~+T细胞依赖的... 石刚,杨茜媚,张郁菁,... - 全国免疫学学术大会摘要 被引量: 0发表: 2018...
例如,结直肠MC38细胞系存在微卫星-不稳定表型( MSI )可形成T细胞炎症的肿瘤微环境,以其对ICB的强大反应。另一方面,结直肠癌CT26细胞系存在微卫星稳定( MSS )模型形成非T细胞炎症肿瘤微环境,且其对ICB反应差。MC38和CT26系的免疫表型特征和对ICB的反应性与临床观察到的MSI和MSS结直肠癌患者的相同。
