The gut microbiota has an essential role in stimulating the development and maintenance of the intestinal immune system – in fact, without the gut microbiome the human body would be unable to protect its health from being affected by all environmental pathogens that enter the body, e.g. through our daily food. The cellular and molecular mechanisms by which this is achieved are nicely illustrated in a video animation that Nature Immunology has released with the expertise of world-renown immunologist Tom MacDonald from London:

Prof. Dr. Paul Enck, Director of Research, Dept. of Psychosomatic Medicine and Psychotherapy, University Hospital Tübingen, Germany. His main interests are gut functions in health and disease, including functional and inflammatory bowel disorders, the role of the gut microbiota, regulation of eating and food intake and its disorders, of nausea, vomiting and motion sickness, and the psychophysiology and neurobiology of the placebo response, with specific emphasis on age and gender contributions. He has published more than 170 original data paper in scientific, peer-reviewed journals, and more than 250 book chapters and review articles. He is board member/treasurer of the European Society of Neurogastroenterology and Motility and of the German Society of Neurogastroenterology and Motility, and has served as reviewer for many international journals and grant agencies.
Foods are processed in the upper digestive tract and pass into the colon when entering the digestive system. A new paper outlines the impact of food consumption in shaping bidirectional communication between digestive responses and the digestive sensations occurring before, during and after a meal.
The last 9th Gut Microbiota for Health World Summit hold in Madrid on March updated the science behind diet, the balance between gut microbiota and the immune system, mental health, food intolerances and functional gut disorders, among others. Check out here the Summit’s official report.
While patients infected with SARS-CoV-2 typically present with a respiratory illness, certain patients also report gastrointestinal symptoms. The presence of virus receptors in gastrointestinal epithelial cells and an altered gut microbiota composition in some patients might have implications for managing COVID-19.
