    Evolution of insect olfactory receptors

    Christine Missbach, Hany KM Dweck ... Ewald Grosse-Wilde
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.

    Olfactory receptor accessory proteins play crucial roles in receptor function and gene choice

    Ruchira Sharma, Yoshiro Ishimaru ... Hiroaki Matsunami
    G protein-coupled odorant receptors regulate their own gene transcription based on their cell surface trafficking, which is facilitated by receptor transporting protein (RTP) family members.

    Adaptation of olfactory receptor abundances for efficient coding

    Tiberiu Teşileanu, Simona Cocco ... Vijay Balasubramanian
    A model of efficient coding by olfactory neurons explains context-dependence observed in the effect of perturbations to the olfactory environment.

    Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

    Colleen N McLaughlin, Maria Brbić ... Hongjie Li
    Single-cell transcriptomes of olfactory receptor neurons at multiple developmental stages reveal cell-type-specific gene expression programs that underlie their development and sensory biology.
    1. Neuroscience

    Olfactory receptor neurons generate multiple response motifs, increasing coding space dimensionality

    Brian Kim, Seth Haney ... Mark A Stopfer
    The odor-elicited responses of olfactory receptor neurons consist of a discrete set of four spike pattern motifs, each with distinct adaptation properties, together amplifying distinctions between similar and temporally complex chemical inputs such as odor plumes.

    Molecular reconstruction of recurrent evolutionary switching in olfactory receptor specificity

    Lucia L Prieto-Godino, Hayden R Schmidt, Richard Benton
    A 'hotspot' position in an olfactory receptor protein family underlies changes in odor tuning in different receptors at different times during evolution.

    Chemoreceptor co-expression in Drosophila melanogaster olfactory neurons

    Darya Task, Chun-Chieh Lin ... Christopher J Potter
    Olfactory neurons of insects, once thought to express only a single type of olfactory receptor, exhibit widespread co-expression of receptors from multiple chemosensory gene families.
    1. Neuroscience

    Diverse states and stimuli tune olfactory receptor expression levels to modulate food-seeking behavior

    Ian G McLachlan, Talya S Kramer ... Steven W Flavell
    Caenorhabditis elegans integrate sensory stimuli and internal state information to alter their expression of olfactory receptors, which impacts the sensorimotor responses of the animal.
    1. Neuroscience

    Systematic morphological and morphometric analysis of identified olfactory receptor neurons in Drosophila melanogaster

    Cesar Nava Gonzales, Quintyn McKaughan ... Chih-Ying Su
    A morphological characterization of Drosophila olfactory receptor neurons—conducted systematically at nanoscale resolution—yields an extensive morphometric dataset, identifies novel features of olfactory sensilla, and raises intriguing questions for how the size and shape of sensory neurons influence their function.

    Olfactory receptor neurons use gain control and complementary kinetics to encode intermittent odorant stimuli

    Srinivas Gorur-Shandilya, Mahmut Demir ... Thierry Emonet
    Olfactory receptor neurons adapt to odorant mean and variance and use complementary kinetics to preserve the timing of odorant encounters, despite adaptation slowing down transduction.
