    EP13:人类肠道噬菌体库

    一支穿云箭,千菌万码来相见!大家好,我是张禅跑。

    今天介绍的文章:

    Shen, J., Zhang, J., Mo, L., Li, Y., Li, Y., Li, C., Kuang, X., Tao, Z., Qu, Z., Wu, L., et al. (2023). Large-scale phage cultivation for commensal human gut bacteria. Cell Host Microbe 31, 665-677.e7. 10.1016/j.chom.2023.03.013.

    肠道里除了细菌还有什么微生物?噬菌体在肠道生态系统中扮演什么角色,它们又是如何调节细菌种群的?中科院深圳先进技术研究院是如何建立一条大规模的噬菌体分离培养的工作流程的?噬菌体的高度特异性意味着什么,这对于肠道微生物群落管理有什么潜在影响?“噬菌体鸡尾酒疗法”是如何工作的,它在实际医疗中有哪些潜在应用?这项人类肠道噬菌体研究对未来的医疗治疗开辟了哪些新途径?

    荐书:《身体的问题,肠知道》

    荐书:《身体的问题,肠知道》

    一支穿云箭,千菌万码来相见!大家好,我是张禅跑。

    今天给大家分享一下我对《身体的问题,肠知道》一书的读后感。这本书由拉施妮·拉杰博士撰写,她是一位专门研究消化道疾病的医生和科普作家。书中用房子比喻人体,探讨肠道菌群在维持健康方面的重要性。书中列举了最新的研究结果,详细解释了“房子”的每个房间与肠道菌群的关系。作者还提供了具体的食谱和建议,旨在帮助读者改善肠道健康。对于希望学习一些基本的肠道菌群与健康的知识的读者,这是一本不错的入门书籍。

    SP12: Gut bacteria make trouble for antidiabetic drugs, new antidiabetic drug from natural products!

    SP12: Gut bacteria make trouble for antidiabetic drugs, new antidiabetic drug from natural products!

    Microbial Matters, a podcast introducing latest microbiome research. I’m Jerry Zhang, a chemical biologist working on human microbiome. In this Podcast, I’m going to share with you newest advances in microbiome research, especially those related to human health.

    What is the link between gut microbiota and metabolic diseases in humans? Which study found the link between obesity and gut microbiota? How does gut microbiota affect Type 2 diabetes? What is the effect of the common antidiabetic drug metformin on intestinal flora? Why are some diabetes patients resistant to acarbose? What is the role of dipeptidyl peptidase 4 (DPP4) in blood sugar regulation? What is the effect of DPP-4 inhibitors on Bacteroides thetaiotaomicron? What are “microbial-host isozymes”? What impact does bacterial DPP4 have on host glucose tolerance? Why doesn't sitagliptin work for some people with diabetes? How does Bacteroides thetaiotaomicron cause trouble? Which active ingredient in traditional Chinese medicine may be a new type of antidiabetic drug?

    1.Tian, J. et al. Inactivation of the antidiabetic drug acarbose by human intestinal microbial-mediated degradation. Nat Metabolism 1–14 (2023) doi:10.1038/s42255-023-00796-w.

    2.Keller, L. J. et al. Chemoproteomic identification of a DPP4 homolog in Bacteroides thetaiotaomicron. Nat. Chem. Biol. 1–11 (2023) doi:10.1038/s41589-023-01357-8.

    3.Wang, K., Zhang, Z., Hang, J., Liu, J., Guo, F., Ding, Y., Li, M., Nie, Q., Lin, J., Zhuo, Y., et al. (2023). Microbial-host-isozyme analyses reveal microbial DPP4 as a potential antidiabetic target. Science 381. 10.1126/science.add5787.
