    Calcium handling precedes cardiac differentiation to initiate the first heartbeat

    Richard CV Tyser, Antonio MA Miranda ... Paul R Riley
    High-resolution live imaging reveals how and when the mouse heart first starts to beat during development and how the onset of beating impacts on heart muscle cell maturation and heart formation.

    Melanopsin activates divergent phototransduction pathways in intrinsically photosensitive retinal ganglion cell subtypes

    Ely Contreras, Jacob D Bhoi ... Tiffany M Schmidt
    Melanopsin phototransduction targets distinct complements of transduction channels across intrinsically photosensitive retinal ganglion cell subtypes and does not require hyperpolarization-activated cyclic nucleotide-gated channels.

    Gi/o protein-coupled receptors in dopamine neurons inhibit the sodium leak channel NALCN

    Fabian Philippart, Zayd M Khaliq
    The sodium leak NALCN channel functions as a core effector of GABA-B and D2 receptors that is used along with GIRK channels to regulate action potential firing in dopamine neurons.

    Distinct dendritic Ca2+ spike forms produce opposing input-output transformations in rat CA3 pyramidal cells

    Ádám Magó, Noémi Kis ... Judit K Makara
    Dendritic patch-clamp recordings combined with two-photon imaging and glutamate uncaging reveal two types of regenerative calcium spikes in the dendrites of CA3 pyramidal neurons from rat hippocampus.

    Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE

    Yao Li, Yu Zhang ... Tingting Yang
    A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.

    Slo1 is the principal potassium channel of human spermatozoa

    Nadja Mannowetz, Natasha M Naidoo ... Polina V Lishko
    Potassium ions enter and leave human sperm cells via a calcium-dependent ion channel that is also pH-independent.

    Structural relationship between the putative hair cell mechanotransduction channel TMC1 and TMEM16 proteins

    Angela Ballesteros, Cristina Fenollar-Ferrer, Kenton Jon Swartz
    The structural relationship between TMC and TMEM16 proteins provides insight into the structure and functional mechanisms of the mechanotransduction channel complex in hair cells.

    Mechanotransduction current is essential for stability of the transducing stereocilia in mammalian auditory hair cells

    A Catalina Vélez-Ortega, Mary J Freeman ... Gregory I Frolenkov
    The remarkable lifelong stability of mechanotransducing stereocilia of the inner ear hair cells depends on the activity of the transduction ion channels located at the tips of these mechanosensory projections.

    Structural insights into the Ca2+-dependent gating of the human mitochondrial calcium uniporter

    Yan Wang, Yan Han ... Youxing Jiang
    Cryo-EM structures of human MCU-EMRE-MICU1-MICU2 complex in the apo and Ca2+-bound states reveal how MICU1 and MICU2 impart their gating function to the mitochondrial calcium uniporter.

    TRPC3 and NALCN channels drive pacemaking in substantia nigra dopaminergic neurons

    Ki Bum Um, Suyun Hahn ... Myoung Kyu Park
    The non-selective Na+ leak channel (NALCN) and the transient receptor potential 3 channel (TRPC3) cooperate in driving pacemaking in substantia nigra dopaminergic neurons.
