New Immune Receptor Identified as Key Driver of Organ Aging

Stanford Medicine researchers have identified a primary driver of biological aging: the failure of tissue-resident macrophages to clear senescent, or “zombie,” neutrophils from the body. According to a study published July 16 in Science, blocking a specific pro-inflammatory receptor, EP2, on these immune cells rejuvenated organ function and reduced age-related frailty in mice. This discovery … Read more

Why Autoimmunity Increases With Age: The Role of Senescent Immune Cells

Immune aging, or immunosenescence, triggers a decline in the body’s ability to fight infections and tumors while simultaneously increasing the risk of chronic inflammation and autoimmune diseases. According to a review published in the Journal of Clinical Investigation, the human immune system reaches a critical inflection point around age 50, where molecular signatures of aging … Read more
