Cancer Immunol Res:确定“喂养”癌细胞,诱导癌症复发的元凶就在我们体内!

一项新的研究显示,癌细胞生存治疗后会利用人体自身的免疫系统来叫醒自己和燃料增长。研究人员发现免疫疗法可以有效防止复发,让身体的免疫反应重回正轨。

一项新的研究显示,癌细胞生存治疗后会利用人体自身的免疫系统来叫醒自己和燃料增长。研究人员发现免疫疗法可以有效防止复发,让身体的免疫反应重回正轨。

来自伦敦癌症研究所的科学家们希望通过了解一小部分的癌细胞,解决休眠很长一段之后的癌细胞重新苏醒的秘密。研究人员分别研究了治疗之前,治疗之后,以及肿瘤复发后小鼠的免疫反应。

这项研究发表在欧洲《癌症免疫学》杂志中,外伤或感染引发炎症反应,正常免疫细胞释放信号,在某些情况下,可以帮助免疫系统杀死癌细胞。但是新的研究表明,这些信号被治疗后残留的癌细胞颠覆,并用于驱动期间成长型复发。至关重要的是,研究人员表明,目标这种反应的免疫疗法可以延缓或预防癌症返回,这表明这种方法可以有效的防止复发的风险。研究人员发现,TNF化学信号开关的作用就是促进癌症复发。除此之外,耐药细胞也能告诉免疫细胞杀伤癌细胞时,睁一只眼闭一只眼,这样癌细胞就可以复发,并且肆意生长。研究人员发现,抗肿瘤细胞有高水平的分子,PD-L1,它会告诉免疫细胞不要攻击T细胞。利用PD-1的这一特点设计目标免疫抑制剂检查站的药物,研究人员发现这样的治疗可以延缓或防止癌症复发。

研究人员表示:“我们的研究发现人体自身的免疫系统在癌症复发时似乎扮演着重要的角色。不仅唤醒癌细胞,而且还喂养着残余细胞,无视他们的增长。”
