Direct toxic action of beta-amyloid identified by a team around Carl von Linde Senior Alumnus Professor Arthur Konnerth – Cause of early cellular dysfunction in Alzheimer’s disease recognized for the first time

13.08.2019


Hyperactive neurons in specific areas of the brain are believed to be an early perturbation in Alzheimer's disease. For the first time, a team around Carl von Linde Senior Alumnus Professor Arthur Konnerth was able to explain the reasons and mechanisms underlying this early and therefore important neuronal dysfunction. They found that the excitatory neurotransmitter glutamate persists for too long near active neurons. This causes a pathological overstimulation of those neurons – most likely contributing critically to impaired learning and memory loss in Alzheimer’s patients.
