Dysfunctional mitochondria are feasibly very harmful and, normally, cells of the damaged mitchondria are disposed by self-eating them, and this process is called mitophagy.

19th August 2013, UK (http://www.kamagramart.com) : Researchers have discovered how genetic mutations associated to Parkinson's disease might play a primary role in the death of brain cells, possibly paving the way for the development of more efficient drug treatments.

They showed how defects in the Parkinson's gene Fbxo7 induce problems with 'mitophagy' - a fundamental process through which the bodies are able to liberate damaged cells. Mitochondria are the 'energy powerhouses' of cells. Their function is essential in nerve cells which need a great deal of energy in order to survive or function. Dysfunctional mitochondria are feasibly very harmful and, normally, cells of the damaged mitchondria are disposed by self-eating them, and this process is called mitophagy.

Most of what everybody knows about the mitophagy process comes from the study of the familial forms of Parkinson's, one of the most normal diseases of the brain. This new study shows just how central the role of mitophagy is and how mutations in Fbxo7 are also linked with the disease and intervene with the PINK1-Parkin pathway. In people with Parkinson's, genetic mutations induce defects in mitophagy, directing to a build-up of dysfunctional mitochondria. This is feasible to explain, the death of brain cells in Parkinson's patients with these mutations.

These findings recommend that treatment strategies that target mitophagy might be developed to benefit patients with Parkinson's disease in the future. This research focuses the attention of the PD community on the importance of the proper maintenance of mitochondria for the health of neurons. Patients can use this information to enable earlier diagnosis for Parkinson's disease.
