Harmful protein aggregates in Alzheimer's disease can spread between neurons in the brain via a cellular waste-disposal system. The new findings by researchers at Linköping University are published in Acta Neuropathologica.

Martin Hallbeck has a foot in two camps: he works not only in research but also as a doctor and head of clinical pathology. His research aims to find out how neurodegenerative diseases spread in the brain and how they can be stopped.

Tiny channels between nerve cells are involved in a newly discovered mechanism of how Parkinson’s disease can spread throughout the brain. Harmful protein aggregates can “hitch a lift” with channel-forming proteins, and spread to healthy cells.
