Aging Weakens Immunity. An mRNA Shot Turned Back the Clock in Mice. (singularityhub.com)

An experimental mRNA treatment has converted the liver into an immune cell "nursery" that pumped out greater numbers of healthy T cells in mice. Since the immune system has a powerful effect on other things like organ health and inflammation, it is hoped that such a treatment in humans might significantly expand our "healthspan", keeping us healthier and more disease-free later in life.
