    Nomograms of human hippocampal volume shifted by polygenic scores

    Mohammed Janahi, Leon Aksman ... Andre Altmann
    Accounting for genetic information improved normative models of hippocampal volume in humans by accounting for change equivalent to around 3 years of normal loss for a person aged 65.

    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.

    Biological brain age prediction using machine learning on structural neuroimaging data: Multi-cohort validation against biomarkers of Alzheimer’s disease and neurodegeneration stratified by sex

    Irene Cumplido-Mayoral, Marina García-Prat ... OASIS study
    Brain-Age delta is a non-invasive marker of biological brain aging that is sensitive to the presence of risk factors and altered biomarkers of Alzheimer's disease in non-demented individuals.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor, Benjamin P Bratton ... Nina R Salama
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    m6A RNA methylation impacts fate choices during skin morphogenesis

    Linghe Xi, Thomas Carroll ... Elaine Fuchs
    METTL3-mediated m6A modification maintains proper cell lineage specification during skin epithelium morphogenesis by coupling transcription and translation of key regulatory pathways.

    An RNAi screen unravels the complexities of Rho GTPase networks in skin morphogenesis

    Melanie Laurin, Nicholas C Gomez ... Elaine Fuchs
    An unprecedented large-scale screen in mice for morphogenetic regulators of tissue development provides major new insights into the roles of Rho GTPases in diverse array of skin developmental processes.

    Longitudinal stability of medial temporal lobe connectivity is associated with tau-related memory decline

    Quanjing Chen, Adam Turnbull ... Feng V Lin
    Phosphorylated tau was related to a loss of structural stability in medial temporal lobe connectivity, and this loss of stability moderated the relationship between phosphorylated tau accumulation and memory decline.

    A zebrafish screen reveals Renin-angiotensin system inhibitors as neuroprotective via mitochondrial restoration in dopamine neurons

    Gha-Hyun J Kim, Han Mo ... Su Guo
    In vivo dopamine neuron imaging-based neuroprotective small molecule screen in larval zebrafish and mechanistic investigation using conditional CRISPR knockout and cell-type-specific RNA-seq analysis, coupled with cross-species analyses including human clinical data interrogation, uncover potential disease-modifying therapeutics for Parkinson's disease (PD).

    Ciliary transcription factors and miRNAs precisely regulate Cp110 levels required for ciliary adhesions and ciliogenesis

    Peter Walentek, Ian K Quigley ... Richard M Harland
    At optimal concentrations, the ciliary inhibitor Cp110 promotes ciliogenesis by localization to previously uncharacterized sites at the basal body, where it recruits ciliary adhesion complexes that mediate basal body interaction with F-actin networks.

    Network structure of brain atrophy in de novo Parkinson's disease

    Yashar Zeighami, Miguel Ulla ... Alain Dagher
    The pattern of atrophy in Parkinson's disease is consistent with the disease spreading via intrinsic brain networks.
