The effects of overexpression of human APP on cholinergic and dopaminergic neurons of brain of Drosophila melanogaster
The influence of APP overexpression on cholinergic and dopaminergic neuronal populations was investigated. The number of cholinergic neurons, which was the same in the control and APP expressing young flies, decreased in the APP expressing flies with age. The number of dopaminergic neurons in APP expressing flies was significantly reduced after the 15th day. Neurodegeneration was followed by the deficit of memory and learning abilities of the flies with APP expression as well as the flies with amyloid-beta-peptide production
