Researchers discover new molecules with longevity boosting potential

Posted by in categories: biotech/medical, life extension, neuroscience

Researchers at the Hebrew University of Jerusalem have discovered a new family of molecules that enable cells to repair damaged components, making it possible for those tissues to retain proper function. The efficacy of the molecules was demonstrated on a model organism – the C. elegans roundworm. The research team examined the effect of various therapies on longevity and quality of life, and successfully showed they can protect the worm and human cells from damage.

The researchers, led by Professors Einav Gross and Shmuel Ben-Sasson, have founded a company called Vitalunga to advance the research and translate it into therapeutics.

Longevity. Technology: A major factor in aging tissues is the reduced effectiveness of our cell’s quality-control mechanism, which leads to the accumulation of defective mitochondria – the cellular ‘power plants’ responsible for energy production. Mitochondria can be compared to tiny electric batteries that help cells function properly. Although these ‘batteries’ wear out constantly, our cells have a sophisticated mechanism called mitophagy that removes defective mitochondria and replaces them with new ones. However, this mechanism declines with age, leading to cell dysfunction and deterioration in tissue activity, and is implicated in many age-related diseases, such as Alzheimer’s disease, Parkinson’s disease, heart failure and sarcopenia.
