Cerebral deposition of beta-amyloid (Abeta) is an invariant event of Alzheimer's disease (AD). We recently described that the brain of aged transgenic mice expressing anti-nerve growth factor (NGF) antibodies (AD11 mice) show a dramatic neurodegenerative phenotype, reminiscent of AD, which includes neuronal loss, cholinergic deficit, and tau hyperphosphorylation, associated with neurofibrillary pathology. We now report that brains of aged transgenic mice contain large amounts of beta-amyloid plaques and describe their morphology by a variety of approaches. In conclusion, the chronic deprivation of NGF leads to the formation and deposition of Abeta in AD11 mice, suggesting a direct link between NGF signaling and abnormal processing of amyloid precursor protein.
