Season 1: The Science of Aging | Episode 6: Cellular Senescence & SASP
In this insightful episode, we delve into the fascinating world of cellular senescence, exploring its role as both a protector and adversary in the aging process. Through engaging discussions and expert insights, we unravel the biological paradox where senescent cells, initially beneficial as safeguards against cancer and critical for tissue repair, become detrimental as they accumulate with age, driving chronic inflammation and degeneration.
We carry listeners through a detailed examination of the intricate mechanisms behind cellular senescence, focusing on pathways involving key proteins like P53 and P16-INK4A, and the complex cocktail of molecules known as the senescence-associated secretory phenotype (SASP). Highlighting landmark mouse studies, we provide compelling evidence of how targeted removal of these cells can delay aging and enhance healthspan, offering hope for potential therapeutic interventions in humans.
Join us on a journey from the microscopic to the macroscopic, as we discuss groundbreaking research that not only reshapes our understanding of aging but also opens up the tantalizing possibility of redefining the very essence of human longevity and health.
