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.
Interestingly enough the vet has yet failed to treat any of my sick gerbils I’ve taken there and they’ve all died. Technically not a mouse but a mole but still.
