概括

肠道中的胰岛素发酵产生 (H2),这可能是胰岛素抗瘤作用的原因. 这项研究表明,H2疗法模仿了胰岛素提高免疫力和抑制黑色素瘤生长的能力.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
微生物学微生物学

背景情况:

胰岛素和 (H2) 在临床前和临床研究中显示出抗瘤作用.
2是肠道微生物群 (GM) 发酵胰岛素的主要副产品.
一个假设表明,H2调解了胰岛素的抗瘤特性.

研究的目的:

调查转基因发酵产生的H2是否调解了因林的抗瘤作用.
建立一个吸入疗法 (H2T) 协议,模仿胰岛素诱导的H2暴露.
为了比较胰岛素和H2T的免疫调节和抗瘤作用.

主要方法:

两周内,小鼠每天接受胰岛素测量或相应的H2T协议.
分析了循环免疫细胞 (CD4 +,CD8 + T 细胞).
评估了黑色素瘤瘤的生长和T淋巴细胞的透.

主要成果:

胰岛素和H2T都显著增加了循环中的CD4+和CD8+T细胞.
胰岛素和H2T表现出类似的抑制黑色素瘤瘤的生长.
在两个治疗组之间,T淋巴细胞透到瘤的情况类似.

结论:

由转基因生物发酵而产生的H2似乎是其抗瘤作用的关键媒介.
吸入的H2疗法可以复制inulin的免疫调节和抗瘤功效.
这支持一种机制,即肠道衍生的H2增强了抗瘤免疫监测.

关键词:

Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
