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.
That’s what this would do. Reducing inflammation has been shown to reduce dementia. In fact studies have shown that people who have gotten routine vaccinations throughout their lives are at lower risk of getting Alzheimers.
