T-cells are essential white blood cells for our immune system, residing in various parts of our body. Scientists have successfully reprogrammed T-cells into anti-aging agents, targeting and destroying senescent cells linked to age-related disorders. The potential of these genetically engineered T-cells for anti-aging effects is promising, offering long-lasting benefits with just one dose. The future of CAR T-cell treatment for aging looks bright, paving the way for a healthier and possibly longer life.
