A recent paper demonstrating that injecting older mice with an anti-IL-11 drug extended their median lifespan made a splash in the geroscience community this summer. IL-11 is a proinflammatory cytokine that plays a role in regulating various biological processes, including hematopoiesis (the production of blood cells), bone health and remodeling, and tissue repair. Meanwhile, cytokines act as messengers between cells, helping to regulate immune responses, inflammation, and the production of blood cells. In excess or when dysregulated, cytokines can contribute to chronic inflammation and autoimmune diseases.

In this episode, Matt discusses the role IL-11 plays in the body, the ERK, AMPK, and mTOR pathways, genetic and pharmacological models of IL-11 reduction, and more. He goes over the paper's claims and provides his take on whether this finding is a game-changer in the longevity field as well as on what further questions he'd like to see answered in follow-up studies.

Hi, I'm Matt Kaeberlein. I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.

On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!
