'Fountain of youth' pill could restore aging immune system
UCSF researchers have identified an existing medication that restores key elements of the immune system that, when out of balance, lead to a steady decline in immunity and health as people age.
The team found that extremely low doses of the drug lenalidomide can stimulate the body's immune-cell protein factories, which decrease production during aging, and rebalance the levels of several key cytokines - immune proteins that either attack viruses and bacteria or cause inflammation that leads to an overall decline in health.
