    Caenorhabditis elegans PIEZO channel coordinates multiple reproductive tissues to govern ovulation

    Xiaofei Bai et al.
    Depletion of the mechanosensitive ion channel PEZO-1 in C. elegans disrupts the sheath and spermathecae cells to disrupt oocyte ovulation, resulting in crushed oocytes.

    Near-infrared photoactivatable control of Ca2+ signaling and optogenetic immunomodulation

    Lian He et al.
    A near-infrared light-stimulable optogenetic platform enables remote and wireless manipulation of calcium signaling and immune responses both in vitro and in vivo to achieve tailored function.

    Neuron-glia signaling in developing retina mediated by neurotransmitter spillover

    Juliana M Rosa et al.
    Retinal waves are correlated with calcium transients in Müller cells, demonstrating that spontaneous activity encompasses both neuronal and glial networks during a crucial period of retinal development.

    Sensitization of neonatal rat lumbar motoneuron by the inflammatory pain mediator bradykinin

    Mouloud Bouhadfane et al.
    The pain mediator bradykinin was found to sensitize spinal motoneurons by a direct postsynaptic action, questioning the role of motoneurons in the assessment of hyperalgesia since the withdrawal motor reflex is commonly used as a surrogate pain model.

    Mitochondria-specific photoactivation to monitor local sphingosine metabolism and function

    Suihan Feng et al.
    Caged, photoactivatible sphingosine localized to mitochondria permits demonstration of the importance of subcellular localization on lipid metabolism and signaling.

    Endothelial Ca2+ oscillations reflect VEGFR signaling-regulated angiogenic capacity in vivo

    Yasuhiro Yokota et al.
    Visualization and quantitative analyses of calcium ion oscillations in the endothelial cells of zebrafish embryos reveal how vascular endothelial growth factor (VEGF) and Dll4/Notch signaling regulate sprouting angiogenesis.

    Single molecule imaging reveals a major role for diffusion in the exploration of ciliary space by signaling receptors

    Fan Ye et al.
    Membrane receptor proteins move through primary cilia largely by passive diffusion rather than by active intraflagellar transport.

    β-blockers augment L-type Ca2+ channel activity by targeting spatially restricted β2AR signaling in neurons

    Ao Shen et al.
    FRET biosensor-based measurement of cAMP signaling and single-channel recording reveal that β-blockers trigger local activation of adrenergic receptors and calcium channels in primary neurons.

    Kv2.1 mediates spatial and functional coupling of L-type calcium channels and ryanodine receptors in mammalian neurons

    Nicholas C Vierra et al.
    A potassium channel, as a nonconducting function, organizes compartmentalized neuronal calcium signaling microdomains via structural and functional coupling of plasma membrane and endoplasmic reticulum calcium channels.

    Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

    Maia Kinnebrew et al.
    The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.
