How the astrocytic urea cycle in the brain controls memory impairment in Alzheimer’s disease

The number of elderly suffering from Alzheimer’s disease has been rapidly rising over the past decades. For a long time, scientists believed that misfolded aggregates of amyloid-beta protein accumulate and form plaques in the brain, leading to memory loss and neuronal death. However, the recent failures of the clinical trials indicate the pressing need to understand the missing link between amyloid-beta protein plaques and the disease’s symptoms, a phenomenon that has been studied for over decades.
