    Cell-type diversity and regionalized gene expression in the planarian intestine

    David J Forsthoefel et al.
    Application of laser-capture microdissection to planarian intestinal tissue provides a new tool for analysis of tissue-specific gene expression in flatworms, and a new resource to advance investigations of gastrointestinal regeneration.

    Mitochondrial ClpX activates an essential biosynthetic enzyme through partial unfolding

    Julia R Kardon et al.
    The mitochondrial protein unfoldase ClpX activates the first enzyme in heme biosynthesis, ALAS, by targeted unfolding that gates access of cofactor to the ALAS active site.

    SLAMF6​ deficiency augments tumor killing and skews toward an effector phenotype revealing it as a novel T cell checkpoint

    Emma Hajaj et al.
    SLAMF6 is an inhibitory checkpoint of T cells, the lack of which leads to better tumor control, suggesting a new immunotherapy target.

    Presynaptic PTPσ regulates postsynaptic NMDA receptor function through direct adhesion-independent mechanisms

    Kyungdeok Kim et al.
    Presynaptic adhesion molecule PTPσ in the hippocampus regulates postsynaptic NMDA receptor function and behavioral novelty recognition through mechanisms independent of their trans-synaptic binding partners.
