    Tachykinin signaling inhibits task-specific behavioral responsiveness in honeybee workers

    Bin Han et al.
    Neuropeptide tachykinin signaling acts as master regulator of behavioral specialization in honeybees by differentially modulating worker responsiveness to task-specific stimuli.

    Synaptotagmin-7 places dense-core vesicles at the cell membrane to promote Munc13-2- and Ca2+-dependent priming

    Bassam Tawfik et al.
    Synaptotagmin-7 acts synergistically with synaptotagmin-1 by placing vesicles close to the plasma membrane within reach of the SNARE/Munc13-complex, supporting their priming and setting the stage for fast and slow fusion.
