    IP3 mediated global Ca2+ signals arise through two temporally and spatially distinct modes of Ca2+ release

    Jeffrey T Lock, Ian Parker
    Cell-wide Ca2+ signals that regulate numerous cellular functions comprise dual Ca2+ release modes through IP3 receptors, punctate transients mediated by clustered receptors and spatiotemporally diffuse release through functionally distinct receptors.

    Identification of drug modifiers for RYR1-related myopathy using a multi-species discovery pipeline

    Jonathan R Volpatti et al.
    A multi-species chemical screening platform reveals a conserved role for p38 inhibition in modulating ryanodine receptor-related phenotypes and is adaptable to a range of neuromuscular disorders.

    Different neuronal populations mediate inflammatory pain analgesia by exogenous and endogenous opioids

    Xin-Yan Zhang et al.
    Exogenous opioid analgesia is mediated by MORs expressed in glutamatergic neurons, whereas endogenous opioid analgesia is mediated by MORs expressed in GABAergic neurons.

    Cell-autonomous regulation of epithelial cell quiescence by calcium channel Trpv6

    Yi Xin et al.
    Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.

    Homologue replacement in the import motor of the mitochondrial inner membrane of trypanosomes

    Corinne von Känel et al.
    Mitochondrial inner membrane translocation of presequence-containing proteins by the single bifunctional TIM complex of T. brucei requires an non-canonical J domain-containing protein.
