How Does the Immune System Age? Explained Through Immunosenescence

How the immune system ages is an important question in longevity science because immune function changes significantly over time. In this video, we explain how the immune system ages, why these changes matter for healthspan, and how immune aging may influence inflammation, resilience, and healthy aging. Full article: https://longevityinsights.co.uk/how-does-the-immune-system-age/ In aging research, immune system aging is often described through processes such as immunosenescence and inflammaging. Over time, the immune system may become less effective at responding to infections while also becoming more prone to chronic low-grade inflammation. Researchers study these changes alongside biomarkers of aging, metabolism, and cellular stress to better understand how immune aging may contribute to reduced resilience, greater disease risk, and the broader biology of aging.
