Axonal Odorant Receptors Mediate Axon Targeting

Cell 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.

PLoS 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.

Tuning Insect Odorant Receptors [PDF]

Frontiers in Cellular Neuroscience, 2018
Among the insect olfactory receptors the odorant receptors (ORs) evolved in parallel to the onset of insect flight. A special property of this receptor type is the capability to adjust sensitivity of odor detection according to previous odor contacts.

Onset of Odorant Receptors [PDF]

Annals of the New York Academy of Sciences, 2009
Odorant receptors are thought to be critical determinants of olfactory sensory neuron axon targeting and organization. Nonetheless, a systematic characterization of the onset of odorant receptor expression has not yet been done in the main olfactory epithelium.

Alternative polyadenylation produces multiple 3’ untranslated regions of odorant receptor mRNAs in mouse olfactory sensory neurons

BMC Genomics, 2019
Background Odorant receptor genes constitute the largest gene family in mammalian genomes and this family has been extensively studied in several species, but to date far less attention has been paid to the characterization of their mRNA 3′ untranslated ...

Odorant Receptor Inhibition Is Fundamental to Odor Encoding [PDF]

Current Biology, 2019
SUMMARYMost 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.

Co-regulation of a large and rapidly evolving repertoire of odorant receptor genes

BMC Neuroscience, 2007
The olfactory system meets niche- and species-specific demands by an accelerated evolution of its odorant receptor repertoires. In this review, we describe evolutionary processes that have shaped olfactory and vomeronasal receptor gene families in ...

Inhibition of insect olfactory behavior by an airborne antagonist of the insect odorant receptor co-receptor subunit. [PDF]

PLoS ONE, 2017
Response to volatile environmental chemosensory cues is essential for insect survival. The odorant receptor (OR) family is an important class of receptors that detects volatile molecules; guiding insects towards food, mates, and oviposition sites.

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.

Asymmetric ephaptic inhibition between compartmentalized olfactory receptor neurons. [PDF]

, 2019
In the Drosophila antenna, different subtypes of olfactory receptor neurons (ORNs) housed in the same sensory hair (sensillum) can inhibit each other non-synaptically.
