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)
INTRODUCTION Among the range of therapeutic protein candidates for new generation treatments of neurological diseases, neurotrophic factors and recombinant antibodies hold the greatest potential. However, major difficulties in their safe and effective delivery to the brain severely limit these applications. The BBB restricts the exchange of proteins between(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)
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)
Alzheimer's disease (AD) is characterized by Aβ overproduction and tau hyperphosphorylation. We report that an early, transient and site-specific AD-like tau hyperphosphorylation at Ser262 and Thr231 epitopes is temporally and causally related with an activation of the endogenous amyloidogenic pathway that we previously reported in hippocampal neurons(More)
Oligomeric amyloid-beta (Abeta) interferes with long-term potentiation (LTP) and cognitive processes, suggesting that Abeta peptides may play a role in the neuronal dysfunction which characterizes the early stages of Alzheimer's disease (AD). Multiple lines of evidence have highlighted RAGE (receptor for advanced glycation end-products) as a receptor(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)
