Get this: researchers at MIT found a way to reboot aging immune systems—using a quick mRNA therapy that turns your liver into a temporary immune booster. In older mice, this trick brought back T-cell power, making vaccines and cancer treatments work better. It’s not a forever fix, but it could mean a stronger defense when you need it most. Human trials are next, but this could be a total game-changer for aging! #Health #BodyHealth #ScienceNews
