Expressing exogenous functional odorant receptors in cultured olfactory sensory neurons

Neural Development, 2008
Background Olfactory discrimination depends on the large numbers of odorant receptor genes and differential ligand-receptor signaling among neurons expressing different receptors.

The narrowing olfactory landscape of insect odorant receptors

Frontiers in Ecology and Evolution, 2015
The molecular basis of odorant detection and its corollary, the task of the odorant receptor, are fundamental to understanding olfactory coding and sensory ecology.

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

Topics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

The Peripheral Olfactory Repertoire of the Lightbrown Apple Moth, Epiphyas postvittana.

PLoS ONE, 2015
The lightbrown apple moth, Epiphyas postvittana is an increasingly global pest of horticultural crops. Like other moths, E. postvittana relies on olfactory cues to locate mates and oviposition sites.

A molecular odorant transduction model and the complexity of spatio-temporal encoding in the Drosophila antenna.

PLoS Computational Biology, 2020
Over the past two decades, substantial amount of work has been conducted to characterize different odorant receptors, neuroanatomy and odorant response properties of the early olfactory system of Drosophila melanogaster. Yet many odorant receptors remain

Sequence comparisons of odorant receptors among tortricid moths reveal different rates of molecular evolution among family members. [PDF]

PLoS ONE, 2012
In insects, odorant receptors detect volatile cues involved in behaviours such as mate recognition, food location and oviposition. We have investigated the evolution of three odorant receptors from five species within the moth genera Ctenopseustis and ...

Insect Odorant Receptors: Channeling Scent [PDF]

Cell, 2008
Odorant detection in insects involves heterodimers between an odorant receptor (OR) and a conserved seven-transmembrane protein called Or83b, but the exact mechanism of OR signal transduction is unclear. Two recent studies in Nature (Sato et al., 2008; Wicher et al., 2008) now reveal that these OR-Or83b heterodimers form odorant-gated ion channels ...

Overlapping but distinct topology for zebrafish V2R-like olfactory receptors reminiscent of odorant receptor spatial expression zones

BMC Genomics, 2018
Background The sense of smell is unrivaled in terms of molecular complexity of its input channels. Even zebrafish, a model vertebrate system in many research fields including olfaction, possesses several hundred different olfactory receptor genes ...

Odorant Binding Causes Cytoskeletal Rearrangement, Leading to Detectable Changes in Endothelial and Epithelial Barrier Function and Micromotion

Biosensors, 2023
Non-olfactory cells have excellent biosensor potential because they express functional olfactory receptors (ORs) and are non-neuronal cells that are easy to culture.

Odorant Receptor Desensitization in Insects [PDF]

Journal of Experimental Neuroscience, 2017
Insects and other arthropods transmit devastating human diseases, and these vectors use chemical senses to target humans. Understanding how these animals detect, respond, and adapt to volatile odorants may lead to novel ways to disrupt host localization or mate recognition in these pests. The past decade has led to remarkable progress in understanding
