This week, I am joined by microbiologist Dr. Sarkis Mazmanian, the Luis B. and Nelly Soux Professor at Caltech, to discuss the microbiome's connection to human health—especially the gut-brain axis. Dr. Mazmanian discusses his research evolution from infectious diseases to the microbiome’s role in neurodevelopment and neurodegeneration, as well as how gut microbes influence neurological health, behavior, and conditions like Parkinson's, autism, and depression. He highlights the human gut microbe symbiosis, early-life microbial exposure's influence, and the adult microbiome's malleability. We explore microbiome-based therapeutics' potential, challenges in translating animal models to humans, personalized medicine's future, the microbiome's impact on drug efficacy, gut bacteria's influence on behaviors and cravings, and the importance of a healthy gut diet. Please enjoy!
