Intranasal Delivery of NEMO-Binding Domain Peptide Prevents Memory Loss in a Mouse Model of Alzheimer's Disease.

ABSTRACT: Alzheimer's disease (AD) is the most common form of dementia. Despite intense investigations, no effective therapy is available to halt its progression. We found that NF-κB was activated within the hippocampus and cortex of AD subjects and that activated forms of NF-κB negatively correlated with cognitive function monitored by Mini-Mental State Examination and global cognitive z score. Accordingly, NF-κB activation was also observed in the hippocampus of a transgenic (5XFAD) mouse model of AD. It has been shown that peptides corresponding to the NF-κB essential modifier (NEMO)-binding domain (NBD) of IκB kinase α (IKKα) or IκB kinase β (IKKβ) specifically inhibit the induction of NF-κB activation without inhibiting the basal NF-κB activity. Interestingly, after intranasal administration, w
