Scientists developed an antibody therapy that rejuvenates immune systems in old mice.
The treatment targets blood stem cells that become unbalanced with age.
A week after receiving an antibody injection, the mice had about 38% fewer of these aberrant stem cells.
Vaccinated treated mice fought off a virus infection better than untreated mice.
Similar therapy might be possible in humans, but with potential side effects.
“By rejuvenating or improving immune function in older people, that could really help with fighting off infections,” - Robert Signer at UC San Diego.
“You might also have an impact on different types of chronic inflammatory diseases.”
This research is a promising step towards boosting immunity in older adults.
