    Neuronal octopamine signaling regulates mating-induced germline stem cell increase in female Drosophila melanogaster

    Yuto Yoshinari, Tomotsune Ameku ... Ryusuke Niwa
    Genetic analyses using the fruit fly illustrate how neuronal system couples germline stem cell increase to an external cue, which is mating, through stem cell niche signaling.

    Octopamine drives honeybee thermogenesis

    Sinan Kaya-Zeeb, Lorenz Engelmayer ... Markus Thamm
    Without octopamine signaling via β octopamine receptors, which likely stimulates glycolysis, thermogenesis performed by the honeybee's indirect flight muscles is not possible.

    An octopamine receptor confers selective toxicity of amitraz on honeybees and Varroa mites

    Lei Guo, Xin-yu Fan ... Jia Huang
    The structural and pharmacological difference of the invertebrate counterpart of β-adrenergic receptor confers selective toxicity of an insecticide on honeybees and their devastating parasite Varroa mites.

    Regulation of starvation-induced hyperactivity by insulin and glucagon signaling in adult Drosophila

    Yue Yu, Rui Huang ... Liming Wang
    Two functionally antagonizing groups of hormones directly regulate starvation-induced increase in locomotion via a common neural target in fruit flies.

    Peptidoglycan-dependent NF-κB activation in a small subset of brain octopaminergic neurons controls female oviposition

    Ambra Masuzzo, Gérard Manière ... Julien Royet
    The universal bacteria cell wall component peptidoglycan impacts the egg-laying behavior of infected Drosophila females by directly modulating the activity of few brain octopaminergic neurons.

    Octopamine integrates the status of internal energy supply into the formation of food-related memories

    Internal states drive nutrient homeostasis by modulating exploration-exploitation trade-off

    Verónica María Corrales-Carvajal, Aldo A Faisal, Carlos Ribeiro
    A quantitative video tracking analysis reveals that to gain the nutrients they need, flies change their decisions to exploit foods with different nutrient contents and explore the environment according to their internal amino acid and reproductive states.

    A sleep state in Drosophila larvae required for neural stem cell proliferation

    Milan Szuperak, Matthew A Churgin ... Matthew S Kayser
    A role for sleep in developmental neurogenesis is revealed using a new system for studying sleep during nascent periods.

    Bidirectional regulation of glial potassium buffering – glioprotection versus neuroprotection

    Hailun Li, Lorenzo Lones, Aaron DiAntonio
    A neuromodulatory circuit bidirectionally regulates the glial capacity to buffer ions and water in response to changes in neuronal excitation in order to balance glial versus neuronal protection.

    Identification of octopaminergic neurons that modulate sleep suppression by male sex drive

    Daniel R Machado, Dinis JS Afonso ... Kyunghee Koh
    The balance between sleep and sex drives determines whether male flies sleep or court, and a subset of octopaminergic neurons interact with the Fruitless-expressing courtship circuit to suppress sleep for sustained courtship.
