Kurzfassung:
In neurons, increased protein–protein interactions between neuronal nitric oxide synthase ( nNOS ) and its carboxy‐terminal PDZ ligand ( CAPON ) contribute to excitotoxicity and abnormal dendritic spine development, both of which are involved in the development of Alzheimer's disease. In models of Alzheimer's disease, increased nNOS – CAPON interaction was detected after treatment with amyloid‐β in vitro, and a similar change was found in the hippocampus of APP / PS 1 mice (a transgenic mouse model of Alzheimer's disease), compared with age‐matched background mice in vivo . After blocking the nNOS – CAPON interaction, memory was rescued in 4‐month‐old APP / PS 1 mice, and dendritic impairments were ameliorated both in vivo and in vitro . Furthermore, we demonstrated that S‐nitrosylation of Dexras1 and inhibition of the ERK – CREB – BDNF pathway might be downstream of the nNOS – CAPON interaction.
