Washington: Scientists have found how genetic mutations associated to Parkinson`s disease may play a key role in brain cells` death, potentially paving the way for the development of more effective drug treatments.A team of researchers from UCL, the University of Cambridge and the University of Sheffield showed how defects in the Parkinson`s gene Fbxo7 cause problems with `mitaphagy` - an essential process through which our bodies are able to get rid of damaged cells.Mitochondria are the `energy powerhouses` of cells. Their function is vital in nerve cells which require a great deal of energy in order to function and survive. Dysfunctional mitochondria are potentially very harmful and, normally, cells dispose of the damaged mitchondria by self-eating them, a process called mitophagy.
