    Model-based whole-brain perturbational landscape of neurodegenerative diseases

    Yonatan Sanz Perl, Sol Fittipaldi ... Enzo Tagliazucchi
    The combination of deep learning with whole-brain computational models reveals the low-dimensional representation of neurodegenerative diseases, which emerges from a highly multidimensional brain, providing valuable insight into pathological states' diagnostic, prognosis, and treatment response.

    Simply crushed zizyphi spinosi semen prevents neurodegenerative diseases and reverses age-related cognitive decline in mice

    Tomohiro Umeda, Ayumi Sakai ... Takami Tomiyama
    Simply crushed zizyphi spinosi semen not only ameliorates Aβ, tau, and α-synuclein pathology in dementia model mice, but also rejuvenates brain function by suppressing cellular senescence in normal aged mice.

    Neurodegenerative disease mutations in TREM2 reveal a functional surface and distinct loss-of-function mechanisms

    Daniel L Kober, Jennifer M Alexander-Brett ... Thomas J Brett
    Structural, biophysical, and functional analyses reveal that mutations in TREM2 trigger either misfolding or reduced binding to cell-surface glycosaminoglycans, which segregate with neurodegenerative disease link and highlight a functional surface linked to the pathogenesis of Alzheimer's disease.

    Differences in topological progression profile among neurodegenerative diseases from imaging data

    Sara Garbarino, Marco Lorenzi ... Daniel C Alexander
    Computational-driven, imaging-based topological profiles of neurodegeneration differ substantially in different neurodegenerative conditions, suggesting distinct modes of dependence of the pathological spread on the underlying connectivity.

    A motor neuron disease-associated mutation produces non-glycosylated Seipin that induces ER stress and apoptosis by inactivating SERCA2b

    Shunsuke Saito, Tokiro Ishikawa ... Kazutoshi Mori
    When non-glycosylated, Seipin, which spans the endoplasmic reticulum (ER) membrane twice, forms aggregates in an oligomerization-dependent manner, distorts the shape of the ER, and incorporates SERCA2b via direct interaction, inactivation of which results in induction of ER stress and apoptosis.

    Determining composition of micron-scale protein deposits in neurodegenerative disease by spatially targeted optical microproteomics

    Kevin C Hadley, Rishi Rakhit ... Avijit Chakrabartty
    STOMP is a technique that can determine the proteomic composition of any feature that is identifiable by laser scanning microscopy and is at least one cubic micron in size.

    The sheddase ADAM10 is a potent modulator of prion disease

    Hermann C Altmeppen, Johannes Prox ... Markus Glatzel
    A lack of ADAM10-mediated shedding increases prion protein levels at the plasma membrane and promotes the generation of pathological prion proteins, which accelerates prion disease in mice.

    TRIM28 regulates the nuclear accumulation and toxicity of both alpha-synuclein and tau

    Maxime WC Rousseaux, Maria de Haro ... Huda Y Zoghbi
    Convergent screens targeting the levels of alpha-synuclein and tau identify TRIM28 as a driver of their stability, nuclear accumulation and subsequent toxicity.

    Distinctive whole-brain cell types predict tissue damage patterns in thirteen neurodegenerative conditions

    Veronika Pak, Quadri Adewale ... Yasser Iturria-Medina
    Major cell types across various brain regions distinctively associate with tissue loss in 13 neurodegenerative conditions.

    Resting-state alterations in behavioral variant frontotemporal dementia are related to the distribution of monoamine and GABA neurotransmitter systems

    Lisa Hahn, Simon B Eickhoff ... Matthias L Schroeter
    Local brain functional activity reductions in bvFTD follow the distribution of serotonergic, GABAergic, and norepinephrinergic neurotransmitter systems, indicating a selective vulnerability and providing novel insights into the underlying disease mechanisms.
