Nec-1 alleviates cognitive impairment with reduction of Aβ and tau abnormalities in APP/PS1 mice.

ABSTRACT: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive symptoms of learning and memory deficits. Such cognitive impairments are attributed to brain atrophy resulting from progressive neuronal and synaptic loss; therefore, alleviation of neural cell death is as an important target of treatment as other classical hallmarks of AD, such as aggregation of amyloid-β (Aβ) and hyperphosphorylation of tau. Here, we found that an anti-necroptotic molecule necrostatin-1 (Nec-1) directly targets Aβ and tau proteins, alleviates brain cell death and ameliorates cognitive impairment in AD models. In the cortex and hippocampus of APP/PS1 double-transgenic mice, Nec-1 treatment reduced the levels of Aβ oligomers, plaques and hyperphosphorylated tau without affecting production
