Navigating Senescence: The Biology Brief ep 9

Delve into the complexities of aging in the latest episode of "The Biology Brief," where hosts Kiley Grant and Dr. Jim Cardelli, the CEO and CTO of Oleolive, unravel the significance of senescence and explore the hallmarks of aging. In this thought-provoking discussion, we examine the dual nature of senescent cells, their positive roles in wound healing and potential positive role in cancer. Join us as we navigate the intriguing connections between senescent cells, exercise, and revolutionary CAR T therapy. Learn about UPAR as the target of CAR T cells, its associated costs, and the challenges in measuring the senescence burden in the body. Beyond UPAR, we explore other senescence markers, emphasizing the importance of targeting specificity in therapies. We'll also break down a relevant paper in this comprehensive exploration. Get a glimpse into the future with discussions on senolytic drugs and a preventive medicine approach.
