Oncotarget:基于免疫应答和肿瘤微环境的重要性,科研中应当选择合适的临床前模型。

2017-06-26 fengxiangxin MedSci原创

现有的人类结直肠癌 (CRC)临床前模型依赖于同源异体皮下移植,但随着越来越多的证据表明皮下组织的免疫微环境明显异于胃肠道的免疫微环境,因此这一建模方式也受到了质疑。同样,现有的使用开腹手术建立的原位移植模型也存在问题,因为手术引起的广泛炎症结果,产生了一种非生理性的肿瘤微环境。

现有的人类结直肠癌 (CRC)临床前模型依赖于同源异体皮下移植,但随着越来越多的证据表明皮下组织的免疫微环境明显异于胃肠道的免疫微环境,因此这一建模方式也受到了质疑。同样,现有的使用开腹手术建立的原位移植模型也存在问题,因为手术引起的广泛炎症结果,产生了一种非生理性的肿瘤微环境。

为了促结直肠癌免疫治疗策略从科研临床的转变,我们通过内镜引导下同源癌细胞显微注射法建立了一种新的小鼠原位模型。当比较免疫浸润情况时,研究者发现肿瘤皮下移植模型有较少的T细胞、B细胞和自然杀伤(NK)细胞,但有更多的免疫抑制髓系细胞;相反,研究者建立的新的原位模型有更多的肿瘤浸润T细胞、B细胞和NK细胞,以及较少免疫抑制髓系细胞。免疫刺激细胞因子的数量,如白细胞介素(IL- 2、IL-6)、干扰素(IFN-γ)和粒酶B在新的原位模型中同样高于皮下移植模型。

这些差异使得内镜引导的原位CRC模型小鼠对免疫检查点阻断疗法的敏感性增强。此研究表明,肿瘤移植位置影响CRC小鼠的免疫应答,选择合适的临床前模型是检测CRC免疫治疗的关键。
