我们研究了口服抗生素消耗肠道微生物组对胰腺癌、结肠癌和黑色素瘤的皮下和肝转移模型中肿瘤生长的影响。在所有测试的模型中,肠道微生物组消耗显著降低了肿瘤负荷。然而,肠道微生物组的消耗并没有减少Rag1基因敲除小鼠的肿瘤生长,这些小鼠缺乏成熟的T和B细胞。流式细胞术分析表明,肠道微生物组消耗导致产生干扰素γ的T细胞显著增加,同时产生白细胞介素17 A和白细胞介素10的T细胞相应减少。我们的研究结果表明,肠道微生物组调节可能成为一种新的免疫策略。
We studied the effects of gut microbiome depletion by oral antibiotics on tumor growth in subcutaneous and liver metastases model of pancreatic cancer, colon cancer and melanoma. Gut microbiome depletion significantly reduced tumor burden in all the models tested. However, depletion of gut microbiome did not reduce tumor growth in Rag1-knockout mice, which lack mature T and B cells. Flowcytometry analyses demonstrated that gut microbiome depletion led to significant increase in interferon gamma-producing T cells with corresponding decrease in interleukin 17A and interleukin 10-producing T cells. Our results suggest that gut microbiome modulation could emerge as a novel immunotherapeutic strategy.
