“Decreased mitochondrial membrane potential is an attractive explanation for the complex dysfunctions of aging.'
surrounds each mitochondrion. The interior layer has accordion-style pleats. Age-related declines in the voltage potential have been noted in earlier modeling studies by others.
Numerous essential functions of these cellular organelles, such as the synthesis of energy molecules, immunological signaling, and genetic regulation, are driven by the mitochondrial membrane potential. “Decreased mitochondrial membrane potential is an attractive explanation for the complex dysfunctions of aging. However, it is unclear if lessening of the mitochondria voltage potential is a cause or a consequence of cellular aging,” said researchers in their study, which was published inTo achieve the elusive goal of verifying causality, the researchers used optogenetics, a technology that uses light to precisely manipulate a biological process inside a cell.
“We were able to show that harnessing the energy of light to experimentally increase mitochondrial membrane during adulthood is alone sufficient to slow the rate ofAccording to the researchers, these findings tend to indicate that it may be possible to directly reverse the age-related reduction of a mitochondrial voltage potential to prevent the roundworms' physiologic decline.Mitochondrial dysfunction plays a central role in aging, but the exact biological causes are still being determined.
