    Structure-based inhibitors of amyloid beta core suggest a common interface with tau

    Sarah L Griner et al.
    Aβ inhibitors effectively block its aggregation, while also reducing seeding of tau aggregation from Aβ, tau, and AD derived fibrils, suggesting the two share a structurally related disease relevant interface.

    Presenilin mutations deregulate mitochondrial Ca2+ homeostasis and metabolic activity causing neurodegeneration in Caenorhabditis elegans

    Shaarika Sarasija et al.
    In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.

    MouseBytes, an open-access high-throughput pipeline and database for rodent touchscreen-based cognitive assessment

    Flavio H Beraldo et al.
    Comprehensive dataset of high-level cognitive assessment in mouse models of neurodegeneration, accompanied by an open-access database/repository to change the paradigm of how cognitive studies in animal models can be shared/re-used.

    Hippocampal activation is associated with longitudinal amyloid accumulation and cognitive decline

    Stephanie L Leal et al.
    Cognitively normal older adults show a positive relationship between neural activity during memory encoding and brain β-amyloid deposition rate over the subsequent 3-4 years, supporting preclinical data that associates neural activity with β-amyloid deposition.

    Clearance of beta-amyloid is facilitated by apolipoprotein E and circulating high-density lipoproteins in bioengineered human vessels

    Jerome Robert et al.
    Modelling beta-amyloid deposition in bioengineered human vessels represents a notable advance to further investigate the role of the vasculature in Alzheimer's disease.

    Sleep is bi-directionally modified by amyloid beta oligomers

    Güliz Gürel Özcan et al.
    Amyloid beta, the major component of plaques in Alzheimer's disease, acutely and reversibly signals to modulate sleep as a function of oligomeric length, independently of neuronal loss.

    The genetic landscape for amyloid beta fibril nucleation accurately discriminates familial Alzheimer’s disease mutations

    Mireia Seuma et al.
    A massively parallel analysis of the effects of mutations on amyloid beta nucleation provide the first comprehensive atlas of how mutations alter the formation of amyloid fibrils.

    The amyloid-beta forming tripeptide cleavage mechanism of γ-secretase

    David M Bolduc et al.
    The protease γ-secretase generates amyloid-beta peptides using a mechanism that is driven by the stabilization of an enzyme-substrate scisson complex.

    Mouse brain transcriptome responses to inhaled nanoparticulate matter differed by sex and APOE in Nrf2-Nfkb interactions

    Amin Haghani et al.
    Transcriptome analysis of mouse brain revealed that the APOE4 allele and sex can alter air pollution neurotoxicity in adults.

    Presynaptic APP levels and synaptic homeostasis are regulated by Akt phosphorylation of huntingtin

    Julie Bruyère et al.
    Reducing Akt-mediated huntingtin phosphorylation decreases APP accumulation at the synapse by reducing its anterograde axonal transport and ameliorates learning and memory in a mouse model of familial Alzheimer disease.
