Neurotrophin nerve growth factor (NGF) has been suggested to be involved in age-related neurodegenerative diseases, but no transgenic model is currently available to study this concept. We have obtained transgenic mice expressing a neutralizing anti-NGF recombinant antibody, in which the levels of antibodies are three orders of magnitude higher in adult(More)
The disruption of the nerve growth factor (NGF) gene in transgenic mice leads to a lethal phenotype (Crowley et al., 1994) and hinders the study of NGF functions in the adult. In this study the phenotypic knockout of NGF in adult mice was achieved by expressing transgenic anti-NGF antibodies, under the control of the human cytomegalovirus promoter. In adult(More)
Brain-derived neurotrophic factor (BDNF) messenger RNA (mRNA) expression in the rat visual cortex of young and postnatal day 90 (P90) animals is developmentally regulated and influenced by visual experience. In the present paper we compared the expression of BDNF mRNA to the actual changes of BDNF protein occurring during postnatal development and verified(More)
The role of nerve growth factor (NGF) and its receptors in the physiology of skeletal muscles has not been extensively studied in animal models. We describe the production of transgenic lines of mice expressing a neutralizing antibody against NGF (alphaD11) and the morphological and histochemical analysis of skeletal muscles from adult and aged anti-NGF(More)
GABA, the main inhibitory transmitter in adulthood, early in postnatal development exerts a depolarizing and excitatory action. This effect, which results from a high intracellular chloride concentration ([Cl(-)](i)), promotes neuronal growth and synaptogenesis. During the second postnatal week, the developmental regulated expression of the cation-chloride(More)
Nerve growth factor (NGF) delivery to the brain of patients appears to be an emerging potential therapeutic approach to neurodegenerative disease, such as Alzheimer's disease (AD). The intranasal route of administration could provide an alternative to intracere-broventricular infusion and gene therapy. We previously showed that intranasal administration of(More)
Soluble amyloid-beta (Abeta) peptide is likely to play a key role during early stages of Alzheimer's disease (AD) by perturbing synaptic function and cognitive processes. Receptor for advanced glycation end products (RAGE) has been identified as a receptor involved in Abeta-induced neuronal dysfunction. We investigated the role of neuronal RAGE in(More)
1. Alzheimer's disease (AD) is pathologically defined by the deposition of amyloid peptide and neurofibrillary tangles and is characterized by a progressive loss of cognition and memory function, due to marked cortical cholinergic depletion. 2. Cholinergic cortical innervation is provided by basal forebrain cholinergic neurons. The neurotrophin Nerve Growth(More)
Alzheimer's disease (AD) is a devastating neurodegenerative disorder characterized by progressive memory deficits and cognitive decline. We explored the possibility that Environmental Enrichment (EE) may reduce the disease progression in a comprehensive mouse model for AD like neurodegeneration, the AD11 mice. AD11 mice, which express anti nerve growth(More)
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(More)
