    Ca2+ sensor synaptotagmin-1 mediates exocytosis in mammalian photoreceptors

    Justin J Grassmeyer et al.
    The vesicular Ca2+ sensor synaptotagmin-1 regulates both fast phasic and slow tonic glutamate release at ribbon synapses of rod and cone photoreceptor cells.

    A Gata3–Mafb transcriptional network directs post-synaptic differentiation in synapses specialized for hearing

    Wei-Ming Yu et al.
    Genetic studies in mice identify the transcription factor MafB as a potent regulator of specific features of the synapses underlying hearing.

    Distinct synaptic transfer functions in same-type photoreceptors

    Cornelius Schröder et al.
    The ribbon synapses of zebrafish UV-cone photoreceptors preferentially transmit transient or sustained components in light-stimuli depending on their location in the eye.

    The presynaptic ribbon maintains vesicle populations at the hair cell afferent fiber synapse

    Lars Becker et al.
    The auditory hair cell synaptic ribbon maintains vesicle pools near release sites in order to support sustained and timed vesicle release.

    Otoferlin acts as a Ca2+ sensor for vesicle fusion and vesicle pool replenishment at auditory hair cell ribbon synapses

    Nicolas Michalski et al.
    Targeted mutations in a Ca2+-binding site of otoferlin, a transmembrane protein of synaptic vesicles defective in a recessive form of deafness, reveal its Ca2+ sensor role both for vesicle fusion and vesicle pool replenishment.

    Neurotrophin-3 regulates ribbon synapse density in the cochlea and induces synapse regeneration after acoustic trauma

    Guoqiang Wan et al.
    Overexpression of the growth factor neurotrophin-3 helps to repair noise-induced damage in the mouse inner ear by promoting the regeneration of damaged synapses.

    Insights into electrosensory organ development, physiology and evolution from a lateral line-enriched transcriptome

    Melinda S Modrell et al.
    An unbiased transcriptomic approach reveals that developing paddlefish electrosensory organs express genes essential for mechanosensory hair cell development and synaptic transmission, and identifies candidates for mediating electroreceptor development and function.

    Nanoscale dynamics of synaptic vesicle trafficking and fusion at the presynaptic active zone

    Thirumalini Vaithianathan et al.
    A combination of tethered diffusion of release-ready synaptic vesicles and vesicle-vesicle fusion supports neurotransmitter release at the presynaptic active zone of sensory synapses.
