PNAS:KWAR23抗体——肿瘤免疫治疗药物的有力助手

2017-11-23 编译自medicalxpress 环球资讯

肿瘤免疫治疗药物有显著但有限的成功,因为在许多情况下,肿瘤对治疗产生抗性。但耶鲁大学和斯坦福大学的研究人员已经确定了一种实验性抗体,通过靶向与肿瘤生长有关的较大范围内的免疫细胞来克服这个问题。相关报告发表在《PNAS》。

肿瘤免疫治疗药物有显著但有限的成功,因为在许多情况下,肿瘤对治疗产生抗性。但耶鲁大学和斯坦福大学的研究人员已经确定了一种实验性抗体,通过靶向与肿瘤生长有关的较大范围内的免疫细胞来克服这个问题。相关报告发表在《PNAS》。

现有的肿瘤免疫疗法仅作用于疾病中涉及的一部分免疫细胞。在该项研究中,研究人员开发了一种抗体KWAR23来阻断一组称为骨髓细胞的免疫细胞。许多这些细胞浸润肿瘤,触发肿瘤生长、炎症和对治疗的抵抗。

在细胞培养和含有人类细胞膜蛋白的小鼠模型中,研究人员发现该抗体阻断了一种蛋白质,否则该蛋白质会限制髓样细胞的肿瘤杀伤能力。联合已批准的肿瘤免疫治疗药物,抗体显著限制了肿瘤细胞的生长。

研究人员表示,这一发现证明了一种有前途的联合治疗方法可以更有效地对抗肿瘤。这也将带来进一步的研究,以调查抗体是否对晚期和转移性肿瘤有效。
