GUT - BRAIN AXIS RESEARCH NETWORK
We were pleased to launch the Gut-Brain Axis Research Network Seminar Series, hosted by the Institute for Personalized and Translational Medicine at Ariel University.
First Seminar
Decoding the Gut Microbiome: Microbes and Metabolites for Future Medicine
Speaker: Prof. Shiri Navon-Venezia, PhD
Our first seminar featured Prof. Shiri Navon-Venezia, Vice President and Dean for Research and Development at Ariel University, who shared insights into the human microbiome, the gut-brain axis, and their growing relevance to health, disease, and personalized medicine.
The lecture focuses on the human gut microbiome and its critical role in health, disease, and the future of personalized medicine. It presents the human body as an ecosystem (a holobiont) where trillions of microbes—primarily in the gut—act as a complex internal “chemical factory” working around the clock.
Key Highlights Covered in the Talk:
Eubiosis vs. Dysbiosis: The transition from a healthy, balanced microbial community (eubiosis) that supports immunity and gut barrier function, to an unbalanced state (dysbiosis) linked to chronic inflammation, “leaky gut,” and various systemic pathologies.
Gut-Brain Axis & Metabolites: How bacterial metabolites, such as short-chain fatty acids (e.g., butyrate, propionate), communicate directly with human physiology, regulate immune responses, and influence the gut-brain connection.
Current & Future Therapeutics: Applications ranging from Fecal Microbiota Transplantation (FMT)—including FDA-approved oral capsules for recurrent C. difficile infections—to emerging frontiers like postbiotics (metabolite-based drugs), precision nutrition, and targeted microbial consortia.
Clinical Challenges: The path forward from preclinical models to human clinical trials, highlighting the need to move beyond simple correlations toward proving direct causal mechanisms.
