Researchers isolate elusive cells that may slow down aging https://www.sciencedaily.com/releases/2025/11/251115095926.htm Neuroscientists find immune cells that may slow aging A special subset of T helper cells may hold the secret to healthy, long-lasting immunity and extended lifespan. Source: Ben-Gurion University of the Negev Summary: A newly recognized set of T helper cells seems to guard against aging by eliminating harmful senescent cells. Their presence in supercentenarians suggests they may be a key to maintaining a healthier, age-balanced immune system. "Prof. Alon Monsonego of Ben-Gurion University of the Negev found that T helper lymphocytes, which are immune cells involved in regulating the body's defenses, shift in function as people grow older. These shifts can reflect a person's biological age, which may not match their chronological age. Within these changes, the research team (the labs of Prof. Monsonego and Prof. Esti Yeger-Lotem) identified a previously unknown group of T helper cells that become more common with age."
