    Ephrin-B3 controls excitatory synapse density through cell-cell competition for EphBs

    Nathan T Henderson, Sylvain J Le Marchand ... Matthew B Dalva
    Competition between neurons for postsynaptic ephrin-B3 controls distribution of a limited pool of synapses and defines a novel trans-synaptic mechanism enabling neurons to set the number of synapses they receive.

    Soluble amyloid-β precursor peptide does not regulate GABAB receptor activity

    Pascal Dominic Rem, Vita Sereikaite ... Bernhard Bettler
    Soluble amyloid-β precursor peptide has no functional effects at recombinant and native GABAB receptors.

    NF1 regulates mesenchymal glioblastoma plasticity and aggressiveness through the AP-1 transcription factor FOSL1

    Carolina Marques, Thomas Unterkircher ... Massimo Squatrito
    Neurofibromatosis type 1 gene (NF1) signaling is causally linked to the acquisition of a mesenchymal gene expression program in gliomas through the regulation of the AP-1 transcription factor FOSL1.

    Characterization of small fiber pathology in a mouse model of Fabry disease

    Lukas Hofmann, Dorothea Hose ... Nurcan Üçeyler
    Globotriaosylcermide directly impacts neuronal integrity and ion channel function as potential mechanism underlying small fiber pathology in Fabry disease.

    Inactivation of the ATMIN/ATM pathway protects against glioblastoma formation

    Sophia M Blake, Stefan H Stricker ... Axel Behrens
    Deletion of the ATM cofactor ATMIN reduces PDGFRA expression and strongly suppresses tumorigenesis in a TP53-deficient mouse model of glioblastoma.

    Neuroinflammation in neuronopathic Gaucher disease: Role of microglia and NK cells, biomarkers, and response to substrate reduction therapy

    Chandra Sekhar Boddupalli, Shiny Nair ... Pramod K Mistry
    In neurodegeneration of Gaucher disease, glucosylceramides trigger neuroinflammation via attrition of homeostatic microglia and transition to lipid-laden damage-associated microglia concurrently with infiltration of diverse immune cells including activated NK cells and CCR2+ macrophages, ameliorated by substrate reduction therapy.

    Single-cell chromatin accessibility profiling of glioblastoma identifies an invasive cancer stem cell population associated with lower survival

    Paul Guilhamon, Charles Chesnelong ... Mathieu Lupien
    Chromatin-based cancer stem cell heterogeneity typifies primary glioblastoma and includes an invasive subtype associated with a lower survival.

    Non-invasive classification of macrophage polarisation by 2P-FLIM and machine learning

    Nuno GB Neto, Sinead A O'Rourke ... Michael G Monaghan
    Human blood derived macrophage polarisation can be classified by proxy of their metabolism, using advanced microscopy techniques generating single-cell parameters that are clustered and validated using machine learning classification models.

    Single-cell characterization of human GBM reveals regional differences in tumor-infiltrating leukocyte activation

    Philip Schmassmann, Julien Roux ... Gregor Hutter
    A regionally resolved single-cell RNA-sequencing analysis of GBM-associated leukocytes reveals distinct activation states of the main immune populations between tumor center, peripheral infiltration zone and blood.

    PITAR, a DNA damage-inducible cancer/testis long noncoding RNA, inactivates p53 by binding and stabilizing TRIM28 mRNA

    Samarjit Jana, Mainak Mondal ... Kumaravel Somasundaram
    PITAR interaction with TRIM28 mRNA, which encodes a p53 targeting E3 ubiquitin ligase, keeps p53 levels low for cancer cells to divide and attenuates the DNA damage response by p53.
