Unraveling the functions of GLP-1 in the gut, with Dr. Thomas Greiner PhD

This episode features Dr. Thomas Greiner PhD from the University of Gothenburg (Sweden), speaking about the various functions of GLP-1 in the gut, and the role of gut microbes in GLP-1 production, with ultimate effects on host health. He noted that GLP-1 is produced by enteroendocrine cells called L-cells, both in the small intestine and […]

Archive Highlight: Microbes that break down mucus and milk to benefit the host, with Dr. Clara Belzer PhD

We discuss microbes, mucus, and milk with Dr. Clara Belzer PhD from Wageningen University in the Netherlands in this episode. Dr. Belzer, a molecular geneticist, specializes in studying the microorganisms that are equipped to break down the glycans in mucus and human milk within the host environment. Key topics from this episode: Dr. Belzer’s research […]

Investigating the microbial mechanisms contributing to host metabolism, with Dr. Amir Zarrinpar, MD PhD

This episode features Dr. Amir Zarrinpar, MD PhD, from UC San Diego (USA) speaking about his work on circadian biology and host metabolism, and what’s currently known about microbial mechanisms. Dr. Zarrinpar explains that in mouse models, restricting feeding to the nocturnal (awake) period is important for their metabolic and overall health. When mice eat […]

Microbiome endpoints in clinical trials for biotics – where do we stand and what have we learnt?

By Marla Cunningham, ISAPP Executive Director I’m sure you’ve read the results of trials similar to these (fictional) conclusions: ‘Our findings showed an increase in Faecalibacterium and Enterococcus, two groups associated with reduced inflammation, and a decrease in Clostridium spp, which have been associated in previous studies with metabolic risk. These results suggest a beneficial […]

Interactions between immunity, gut microbiota, and metabolism, with Prof. Dirk Haller PhD

This episode features Prof. Dirk Haller from Technical University of Munich (Germany) speaking about his work in the field of nutritional immunology, trying to unravel how immunity and gut microbiota interact with metabolism, ultimately impacting the emergence of chronic diseases. He focuses on how microbe-host interactions in the gut impact inflammatory or tumorigenic responses – […]

Examining fermented foods for potential cardiometabolic health benefits, with Prof. Ben Willing PhD

This episode features Prof. Ben Willing PhD from the University of Alberta, Canada, speaking about his work investigating fermented foods such as kefir for potential cardiometabolic health benefits. The microorganisms associated with fermented foods are not standardized – for example, traditional kefirs have some microorganisms in common, but other microorganisms that are present sporadically. Moreover, kefir […]

Diet and gut microbiome contributions to host energy balance, with Dr. Karen Corbin PhD RD

This episode features Dr. Karen Corbin PhD RD from AdventHealth Translational Research Institute (USA), speaking about how the triad of diet, gut microbiome, and host characteristics contribute to energy balance as well as metabolic diseases. From the perspective of host physiology, she explores how to use diet to remodel the gut microbiome to impact energy […]
