    Pathogenic LRRK2 control of primary cilia and Hedgehog signaling in neurons and astrocytes of mouse brain

    Shahzad S Khan et al.
    Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.

    Pathogen clonal expansion underlies multiorgan dissemination and organ-specific outcomes during murine systemic infection

    Karthik Hullahalli, Matthew K Waldor
    During Escherichia coli systemic infection, the replication of a minuscule fraction of the inoculum drives organ-specific clearance failures, systemic dissemination, and stochastic infection outcomes.

    Multiscale analysis reveals that diet-dependent midgut plasticity emerges from alterations in both stem cell niche coupling and enterocyte size

    Alessandro Bonfini et al.
    The nutrient composition of food alters both the size of gut epithelial cells and the ability of the stem cell niche to control tissue turnover, resulting in changes in size at the organ level.

    The structure of behavioral variation within a genotype

    Zachary Werkhoven et al.
    Multidimensional analysis of data from high-throughput behavioral assays reveals many independent axes of behavioral variation among inbred animals reared in the same environment.

    Microglia and CD206+ border-associated mouse macrophages maintain their embryonic origin during Alzheimer’s disease

    Xiaoting Wu et al.
    Inducible fate-mapping analysis demonstrates that neither microglia, CD11c+ activated microglia nor border-associated macrophages are replenished by bone marrow-derived cells in Alzheimer’s disease.

    Dynamic dichotomy of accumbal population activity underlies cocaine sensitization

    Ruud van Zessen et al.
    Cocaine elicits opposing activity changes in D1R vs D2R spiny projection neurons of the nucleus accumbens with much variability, subsequent recruitment of a subset of D1R neurons drives behavioral sensitization.

    Linking functional and molecular mechanisms of host resilience to malaria infection

    Tsukushi Kamiya et al.
    With a data-driven mathematical modelling approach, within-host ecological information alone can provide clues on the mechanistic basis of diverse malaria infection outcomes.

    Structural variability and concerted motions of the T cell receptor – CD3 complex

    Prithvi R Pandey et al.
    The orientation of the TCR extracellular domain is highly variable and coupled to characteristic structural changes throughout the TCR - CD3 complex.

    Y chromosome functions in mammalian spermatogenesis

    Jeremie Subrini, James Turner
    The mammalian Y chromosome has become specialised for male fertility, but exact functions of individual Y genes remain poorly understood, a knowledge gap that new approaches can bridge.

    Temporo-cerebellar connectivity underlies timing constraints in audition

    Anika Stockert et al.
    With unique lesion-informed tractography, left hemisphere temporo-cerebellar structural connectivity has been established, supporting rapid auditory transmission and cortical functional lateralization.
