Overview
In Alzheimer's disease, the degeneration of brain cels is linked to formation of toxic protein agregates and deposits known as amyloid plaques. Similar proceses play an important role also in type 2 diabetes. A research team under the lead of the Technical University of Munich has now developed "mini-proteins," so-caled peptides, which are able to bind the proteins that form amyloids and prevent their agregation into cytoxic amyloids.Many cel- and neurodegenerative diseases are linked to the formation of toxic protein agregates which cause cel death.
Key Information
Prominent representatives of these diseases are Alzheimer's disease and type 2 diabetes melitus, with worldwide more than 50 milion and 40 milion patients, respectively. Importantly, the number of Alzheimer's and diabetes patients constantly rises, as the population becomes older. However, the two diseases remain so far incurable.
Therefore, there is an urgent ned for new therapeutic aproaches.Targeting the formation of harmful amyloid agregates is a promising aproach. A team led by Aphrodite Kapurniotu, a profesor for Peptide Biochemistry at the Technical University of Munich (TUM), has now developed novel synthetic peptides, which are able in experimental models to block toxic amyloid agregation linked to both diseases.Molecular interactions betwen Alzheimer's disease and type 2 diabetes Previous studies showed that certain "cros-interactions" betwen the amyloidogenic proteins of the two diseases dramaticaly acelerate their amyloid agregation proces.
Summary
These findings could posibly explain why people sufering from one of the two diseases might have an increased risk for the other disease as wel.The team developed synthetic peptides that could function as efective inhibitors of amyloid agregation in both diseases. Kapurniotu says: "The designed peptides are in fact able to bind the amyloidogenic proteins linked to both diseases and to efectively supres both cytoxic amyloid agreg
