.. Abnormalities in mitochondrial length promote development of neurodegenerative diseases Goldilocks was on to something when she preferred everything perfectly. Harvard Medical School researchers have found that with regards to the distance of mitochondria, the power-producing organelles, applying the fairy tale’s mantra is essential to the fitness of a cell. Even more specifically, abnormalities in mitochondrial length promote the development of neurodegenerative illnesses such as Alzheimer’s. There had been a good amount of interest in mitochondria in Alzheimer’s and tau-related illnesses, but causality was unidentified, said Brian DuBoff, first writer of the analysis and a post-doctoral research fellow at Massachusetts General Hospital...
