Viral gene transfer of APPsα rescues synaptic failure in an Alzheimer's disease mouse model

R Fol, J Braudeau, S Ludewig, T Abel, SW Weyer… - Acta …, 2016 - Springer
Alzheimer’s disease (AD) is characterized by synaptic failure, dendritic and axonal atrophy,
neuronal death and progressive loss of cognitive functions. It is commonly assumed that …

Activity requires soluble amyloid precursor protein α to promote neurite outgrowth in neural stem cell‐derived neurons via activation of the MAPK pathway

…, P Hundeshagen, C Mandl, SW Weyer… - European Journal of …, 2008 - Wiley Online Library
It is known that activity modulates neuronal differentiation in the adult brain but the signalling
mechanisms underlying this process remain to be identified. We show here that activity …

X Zhang, W Zhong, J Brankačk, SW Weyer… - Scientific reports, 2016 - nature.com
Amyloid precursor protein (APP) is critically involved in the pathophysiology of Alzheimer’s
disease, but its physiological functions remain elusive. Importantly, APP knockout (APP-KO) …

Functions of the APP gene family in the nervous system: insights from mouse models

D Aydin, SW Weyer, UC Müller - Experimental brain research, 2012 - Springer
The amyloid precursor protein (APP) plays a key role in the pathogenesis of Alzheimer’s
