- The Effects of Cellular Senescence and Senolytics on Healthspan with Dr. James Kirkland InsideTracker 1:12:14
Do you know what senescent (zombie) cells are and how cellular senescence and senolytics impact health? In this episode of Longevity by Design, hosts Ashley Reaver and Dr. Gil Blander are joined by Dr. James Kirkland from the Mayo Clinic, one of the world's leading figures in aging research. This episode is a deep dive into aging research, cellular senescence, and senolytics. Dr. Kirkland discusses the impact of cellular aging (senescence) on healthspan and his discovery of the first senolytic agents that remove senescent cells and extend healthspan, illuminating his pioneering work in aging research.
Dr. Kirkland shares insights into the science of cellular senescence and how selectively eliminating these cells could revolutionize the treatment of age-related chronic diseases. He sheds light on the mechanisms behind senolytics and their promise for extending healthspan. The discussion also touches on the importance of lifestyle factors like diet and exercise in managing senescent cells.Â
Dr. Kirkland also discusses geroscience, a research paradigm that seeks to understand the mechanisms of aging and how this knowledge can be used to slow the rate of aging, reverse its effects, delay or even cure age-related diseases, and extend healthspan. T Dr. Kirkland also covers the challenges and opportunities in translating these scientific discoveries into clinical applications, emphasizing the critical role of interdisciplinary efforts in advancing our understanding and management of aging.
This is an enlightening episode with Dr. Kirkland on aging research and the opportunities to revolutionize healthcare by combating aging-related diseases and extending people’s health span and lifespan.
