Intracerebral administration of AB1-42 (AβO) oligomers disrupts synaptic function and increases cell death in brain tissue in aged mice. As announced a few weeks ago, we evaluated the effects of AβO on synaptic function and cell survival. Quantification of protein expression in the hippocampus 18 days after intracerebral administration showed disruption to synaptic function (PSD-95) and apoptotic signalling in brain tissue.
