    The cation channel mechanisms of subthreshold inward depolarizing currents in the mice VTA dopaminergic neurons and their roles in the chronic-stress-induced depression-like behavior

    Jing Wang, Min Su ... Hailin Zhang
    NALCN and TRPC6 drive the subthreshold depolarization of VTA DA neurons and down regulation of TRPC6 contributes to reduced VTA DA neuron firing and chronic stress-induced depression-like behavior of mice.

    ER-to-lysosome Ca2+ refilling followed by K+ efflux-coupled store-operated Ca2+ entry in inflammasome activation and metabolic inflammation

    Hyereen Kang, Seong Woo Choi ... Myung-Shik Lee
    The role of lysosomal Ca2+ flux associated with K+ efflux, a well-known event in inflammasome activation in metabolic inflammation and inflammasome activation, has been presented.

    Structural features of heteromeric channels composed of CALHM2 and CALHM4 paralogs

    Katarzyna Drożdżyk, Martina Peter, Raimund Dutzler
    Structural studies revealing the organization of assemblies consisting of CALHM2 and CALHM4 subunits provide insight into the mechanism of heteromerization of large pore channels.

    Activation of the P2RX7/IL-18 pathway in immune cells attenuates lung fibrosis

    Serena Janho dit Hreich, Thierry Juhel ... Valerie Vouret-Craviari
    The use of a small activator of P2RX7 highlights the importance of the P2RX7 pathway to enhance the antifibrotic properties of lung immune cells.

    Astrocyte and L-lactate in the anterior cingulate cortex modulate schema memory and neuronal mitochondrial biogenesis

    Mastura Akter, Mahadi Hasan ... Ying Li
    Astrocytic Gi pathway activation in the anterior cingulate cortex impairs schema memory and neuronal mitochondrial biogenesis, which can be rescued by exogenous L-lactate administration directly into the area.

    The Opto-inflammasome in zebrafish as a tool to study cell and tissue responses to speck formation and cell death

    Eva Hasel de Carvalho, Shivani S Dharmadhikari ... Maria Leptin
    Manipulating cell death in situ with the temporal and spatial precision of optogenetic tools opens up new avenues for studying inflammation, death and related phenomena, revealing, for example, that epithelial cell death cannot be classified into strictly distinct categories.

    Purinergic GPCR-integrin interactions drive pancreatic cancer cell invasion

    Elena Tomas Bort, Megan D Joseph ... Richard P Grose
    New role of P2Y2-αV integrin interactions in ATP-driven pancreatic cancer cell invasion provides a potential anti-metastatic target for pancreatic cancer.

    Cryo-EM structures of an LRRC8 chimera with native functional properties reveal heptameric assembly

    Hirohide Takahashi, Toshiki Yamada ... Erkan Karakas
    The cryo-electron microscopy structures of an LRRC8C chimera with native channel properties reveal the diverse oligomeric assembly and suggest that lipids may play a role in gating in volume-regulated anion channels.
