Can Aging Intestines Heal? CAR T-Cell Therapy Sparks New Hope for Gut Regeneration
*CAR T-cell therapy removes senescent cells, allowing intestinal stem cells to regenerate damaged gut tissue / Freepik Aging and damage to the intestinal lining have long been linked with digestive dysfunction, chronic inflammation, and reduced nutrient absorption. Recent scientific discoveries have uncovered an innovative approach using advanced immunotherapy — originally developed for cancer treatment — to rejuvenate aging intestines and restore intestinal health. Why Intestinal Health Declines With Age The intestine plays a vital role in digestion and overall health. Its inner lining, known as the intestinal epithelium , is responsible for nutrient absorption and forming a protective barrier against harmful microbes and toxins. Under ideal conditions, this epithelial layer naturally regenerates itself every three to five days. However, with aging or following cancer treatment like radiation therapy, this regenerative capacity declines. As a result: Inflammation ...
