    A putative origin of the insect chemosensory receptor superfamily in the last common eukaryotic ancestor

    Richard Benton et al.
    Comparative genomics and three-dimensional protein modelling identify homologs of insect chemosensory receptors in unicellular eukaryotes and plants.

    C. elegans avoids toxin-producing Streptomyces using a seven transmembrane domain chemosensory receptor

    Alan Tran et al.
    Caenorhabditis elegans require a GPCR to recognize and rapidly escape from toxin-producing Streptomyces at their head or tail.
    1. Neuroscience

    Male pheromones modulate synaptic transmission at the C. elegans neuromuscular junction in a sexually dimorphic manner

    Kang-Ying Qian et al.
    Male pheromone environment increases the cholinergic synaptic transmission at the neuromuscular junction in Caenorhabditis elegans hermaphrodites during development, decreasing hermaphrodites' locomotion activity and promoting mating efficiency.

    Internal amino acid state modulates yeast taste neurons to support protein homeostasis in Drosophila

    Kathrin Steck et al.
    Two different classes of taste receptor neurons in the Drosophila melanogaster proboscis play distinct roles in yeast feeding and are both modulated by the fly's internal amino acid state in order to promote protein-specific appetite.

    Oxytocin modulates human chemosensory decoding of sex in a dose-dependent manner

    Kepu Chen et al.
    Oxytocin, but not the structurally similar vasopressin, modulates both the chemosensory decoding of femininity in straight men and that of masculinity in gay men in an inverted-U-shaped manner.

    Distinct roles for innexin gap junctions and hemichannels in mechanosensation

    Denise S Walker, William R Schafer
    The innexin protein UNC-7, a homologue of vertebrate pannexins, plays a specific, gap junction-independent role in C. elegans mechanosensation.

    NHR-8 and P-glycoproteins uncouple xenobiotic resistance from longevity in chemosensory C. elegans mutants

    Gabriel A Guerrero et al.
    Separate genetic pathways mediate longevity, pathogen resistance, and cell-nonautonomous regulation of xenobiotic detoxification in chemosensory defective Caenorhabditis elegans mutants.

    Evolved differences in larval social behavior mediated by novel pheromones

    Joshua D Mast et al.
    A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.
    1. Neuroscience

    Semiochemical responsive olfactory sensory neurons are sexually dimorphic and plastic

    Aashutosh Vihani et al.
    Semiochemicals activate a subpopulation of sexually dimorphic olfactory sensory neurons.
    1. Neuroscience

    Distinct combinations of variant ionotropic glutamate receptors mediate thermosensation and hygrosensation in Drosophila

    Zachary A Knecht et al.
    A combination of genetics, behavior and physiology demonstrate that cool and moisture sensing rely on overlapping combinations of sensory receptors in Drosophila.
