The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.
