Hi wapta
Thanks for interesting insight to various roles out gut plays to our immune system. I too became a student of cancer since I was diagnosed NMBIC almost a year ago. I think I started learning about cancer as my coping mechanism. Though I do not have any medical, chemical, biology background, I find learning about cancer is fascinating thanks to internet and many cancer related books. The best book I ever read on cancer is “The emperor of of all maladies” by Dr. Siddhartha Mukherjee. The book won Pulitzer prize in 2011. IF you had not read the book, I highly recommend it. I think most libraries carry it.
After I read your post, I have found the following site http://www.clevelandclinicmeded.com/online/webcasts/clinical-immunology/2018/microbiome/webcast.asp.
The attached paper says pretty much what your Nature article says. https://pubs.acs.org/doi/ipdf/10.1021/acs.biochem.7b012
