Advantage of the Highly Restricted Odorant Receptor Expression Pattern in Chemosensory Neurons of Drosophila. [PDF]

open access: yesPLoS ONE, 2013
A fundamental molecular feature of olfactory systems is that individual neurons express only one receptor from a large odorant receptor gene family. While numerous theories have been proposed, the functional significance and evolutionary advantage of ...

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

open access: yesPLoS 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

Odorant Receptor Inhibition Is Fundamental to Odor Encoding [PDF]

open access: yesCurrent Biology, 2019
SUMMARY Most natural odors are complex mixtures of many volatile components, competing to bind odorant receptors (ORs) expressed in olfactory sensory neurons (OSNs) of the nose. To date surprisingly little is known about how OR antagonism shapes neuronal representations in the periphery of the olfactory system.

Application of artificial intelligence to decode the relationships between smell, olfactory receptors and small molecules

open access: yesScientific Reports, 2022
Deciphering the relationship between molecules, olfactory receptors (ORs) and corresponding odors remains a challenging task. It requires a comprehensive identification of ORs responding to a given odorant.

Research Progress of Insect Odorant Receptors

open access: yesGuangdong nongye kexue, 2022
For insects, olfaction is an important signal input source for their behavioral perception. There are many kinds of proteins involved in the process of odor recognition, and they play a leading role in regulating feeding, swarming, mating, oviposition ...

Selectivity of odorant receptors in insects [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2012
Insect olfactory receptors (ORs) detect chemicals, shape neuronal physiology, and regulate behavior. Although ORs have been categorized as "generalists" and "specialists" based on their ligand spectrum, both electrophysiological studies and recent pharmacological investigations show that ORs specifically recognize non-pheromonal compounds, and that our

Characterisation of Bombyx mori odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components [PDF]

open access: yes, 2009
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

Axonal Odorant Receptors Mediate Axon Targeting

open access: yesCell Reports, 2019
Summary: In mammals, odorant receptors not only detect odors but also define the target in the olfactory bulb, where sensory neurons project to give rise to the sensory map.

Dynamics of odor sampling strategies in mice.

open access: yesPLoS ONE, 2020
Mammalian olfactory receptor neurons in the nasal cavity are stimulated by odorants carried by the inhaled air and their activation is therefore tied to and driven by the breathing or sniffing frequency.

An Olfactory Receptor Pseudogene whose Function emerged in Humans [PDF]

open access: yes, 2007
Human olfactory receptor, hOR17-210, is identified as a pseudogene in the human genome. Experimental data has shown however, that the gene product of cloned hOR17-210 cDNA was able to bind an odorant-binding protein and is narrowly tuned for excitation ...
