    A novel synaptic plasticity rule explains homeostasis of neuromuscular transmission

    Gilles Ouanounou et al.
    Skeletal muscle cells constantly monitor their own activity and that of their partner neuron at synapses, enabling them to provide the neuron with feedback regarding neurotransmitter release.

    NG2 glial cells integrate synaptic input in global and dendritic calcium signals

    Wenjing Sun et al.
    NG2 glial cells respond to synaptic input with calcium signals in the absence of action potentials and process synaptic depolarizations with somatic and dendritic voltage gated channels.

    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.

    An hourglass circuit motif transforms a motor program via subcellularly localized muscle calcium signaling and contraction

    Steven R Sando et al.
    By driving the localized contraction of subcellular muscle regions, a single motor neuron reverses the flow of material in the Caenorhabditis elegans pharynx, a neuromuscular pump, converting feeding into spitting.

    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.
