abstractText | Neurogenesis is a subject of intense interest and extensive research, but it stands at the center of a bitter debate over ethical and practical problems. Neurodegenerative diseases, such as Alzheimer's disease (AD), accompanied by a shifting balance between neurogenesis and neurodegeneration, are suitable for stimulation of neurogenesis for the benefit of diseased patients. We have previously shown that Abs against the EFRH sequence of beta-amyloid peptide (AbetaP) prevent aggregation and disaggregate AbetaP both in vitro and in vivo. EFRH, located in the soluble tail of the N-terminal region, acts as a regulatory site controlling both solubilization and disaggregation processes in the AbetaP molecule. Here we show that anti-EFRH immunotherapy of a platelet-derived amyloid precursor protein transgenic mouse model of AD stimulates endogenous neurogenesis, suggested by elevated numbers of BrdU-incorporated cells, most of which are colocalized with a marker of mature neurons, NeuN. These newly born neurons expressed the activity-dependent gene Zif268, indicating their functional integration and participation in response to synaptic input in the brain. These findings suggest that anti-amyloid immunotherapy may promote recovery from AD or other diseases related to AbetaP overproduction and neurotoxicity by restoring neuronal population, as well as cognitive functions in treated patients. |
