The researchers, led by Associate Professor Ana Maria Cuervo, blocked the ageing process in mice livers by stopping the build-up of harmful proteins inside the organ's cells.
As people age their cells become less efficient at getting rid of damaged protein resulting in a build-up of toxic material that is especially pronounced in Alzheimer's, Parkinson's and other neurodegenerative disorders.
The researchers say the findings suggest that therapies for boosting protein clearance might help stave off some of the declines in function that accompanies old age.
