The researchers suppose that therefore the mitochondria will stop he energy supply step by step causing the dead of the nerve cells.
To study the scientists cultivated isolated mitochondria together with beta amyloids in order to investigate the disturbance of protein transport into the mitochondria. As next step they want study whether this kind of mitochondria protein blockade also occurs in neurons of patients suffering from Alzheimer´s.

Alzheimer's research in vitro: beta amyloids leds to protein blockade in mitochondria Featured
Researcher from the Institute of Biochemistry and Molecular Biology at Bonn University led by Professor Wolfgang Voos have decrypted a new mechanism which possibly contributes to the development of the Alzheimer´s disease. Thus, the beta amyloid depositions are not responsible for the dying of nerve cells but they prevent the supply of important proteins into the mitochondria.
