By blocking the action of a single protein, scientists have extended the average life span of the mice in their experiment by around 25%. This recent finding has raised the question of whether such a treatment could ever work for people, and so far, there are some promising early hints that it might.
In the new study, scientists injected middle-aged mice with an antibody that blocks the action of interleukin-11, a protein that spurs inflammation and has been tied to aging processes in human cells.
