    Snf1/AMPK fine-tunes TORC1 signaling in response to glucose starvation

    Marco Caligaris, Raffaele Nicastro ... Claudio De Virgilio
    Discovery of new Snf1/AMPK targets in the TORC1 pathway highlights the complex, multilayered crosstalk between major signaling pathways in the regulation of nutrient deprivation sensing.

    Tracking multiple conformations occurring on angstrom-and-millisecond scales in single amino-acid-transporter molecules

    Yufeng Zhou, John H Lewis, Zhe Lu
    The present fluorescence polarization microscopy method enables the determination of the spatial orientations and lifetimes of a transporter protein in individual conformational states required for understanding the complex conformational mechanism underlying its function, applicable to investigation of other membrane proteins.

    The anti-caspase 1 inhibitor VX-765 reduces immune activation, CD4+ T cell depletion, viral load, and total HIV-1 DNA in HIV-1 infected humanized mice

    Mathieu Amand, Philipp Adams ... Carole Seguin-Devaux
    Inflamasomme inhibition prevents immune activation, HIV-1 pathogenesis and the splenic content of HIV-1 total DNA in humanized mice when administrated early after HIV-1 infection.

    Quantifying changes in the T cell receptor repertoire during thymic development

    Francesco Camaglia, Arie Ryvkin ... Nir Friedman
    Sequence signatures can be used to discriminate between selected and non-selected immune repertoires at different stages only at the collective population level but not at the level of single cells.

    Lack of evidence for increased transcriptional noise in aged tissues

    Olga Ibañez-Solé, Alex M Ascensión ... Ander Izeta
    An increase in transcriptional noise generally assumed to characterize aged cells and tissues is shown to derive instead from technical and biological issues that underlie single-cell RNA sequencing experiments.

    Cellular composition and circuit organization of the locus coeruleus of adult mice

    Andrew McKinney, Ming Hu ... Xiaolong Jiang
    Interrogating mouse locus coeruleus via large-scale multipatch whole-cell recordings uncovers its cellular heterogeneity and cell-type-specific wiring logic.

    The impact of the COVID-19 pandemic on Italian population-based cancer screening activities and test coverage: Results from national cross-sectional repeated surveys in 2020

    Paolo Giorgi Rossi, Giuliano Carrozzi ... Paola Mantellini
    The COVID-19 pandemic caused an important delay in screening activities at the national level and increased the pre-existing individual and geographical inequalities in access.

    B cell receptor-induced IL-10 production from neonatal mouse CD19+CD43- cells depends on STAT5-mediated IL-6 secretion

    Jiro Sakai, Jiyeon Yang ... Mustafa Akkoyunlu
    A novel B cell receptor induced interleukin 10 (IL-10) production from B10 cells involves signal transducer and activator of transcription 5 (STAT5) mediated IL-6 production which induces IL-10 in an autocrine and paracrine fashion from B10 cells.

    The tetraspanin TSPAN5 regulates AMPAR exocytosis by interacting with the AP4 complex

    Edoardo Moretto, Federico Miozzo ... Maria Passafaro
    In mature neurons, TSPAN5 assembles into a complex with AP4 and Stargazin to promote the exocytosis of AMPA receptors.

    MorphoFeatures for unsupervised exploration of cell types, tissues, and organs in volume electron microscopy

    Valentyna Zinchenko, Johannes Hugger ... Anna Kreshuk
    Unsupervised machine learning on the ultrastructure and shape of cells in volume electron microscopy yields a compact representation of cellular morphology that complements genetics-based cell type characterisation.
