Adaptation of olfactory receptor abundances for efficient coding

open access: yes, 2019
Olfactory receptor usage is highly heterogeneous, with some receptor types being orders of magnitude more abundant than others. We propose an explanation for this striking fact: the receptor distribution is tuned to maximally represent information about ...

Odorant receptors of Drosophila are sensitive to the molecular volume of odorants

open access: yesScientific Reports, 2016
Which properties of a molecule define its odor? This is a basic yet unanswered question regarding the olfactory system. The olfactory system of Drosophila has a repertoire of approximately 60 odorant receptors.

Evaluation of the DREAM Technique for a High-Throughput Deorphanization of Chemosensory Receptors in Drosophila

open access: yesFrontiers in Molecular Neuroscience, 2018
In the vinegar fly Drosophila melanogaster, the majority of olfactory receptors mediating the detection of volatile chemicals found in their natural habitat have been functionally characterized (deorphanized) in vivo. In this process, receptors have been

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

open access: yesJournal of Anatomy, EarlyView.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

Functional analysis of Orco and odorant receptors in odor recognition in Aedes albopictus

open access: yesParasites & Vectors, 2016
Aedes albopictus is a globally invasive mosquito and a major vector of arboviruses, including dengue, Zika and Chikungunya. Olfactory-related behaviors, particularly host-seeking, offer opportunities to disrupt the disease-transmission process.

Functional evolution of mammalian odorant receptors.

open access: yesPLoS Genetics, 2012
The mammalian odorant receptor (OR) repertoire is an attractive model to study evolution, because ORs have been subjected to rapid evolution between species, presumably caused by changes of the olfactory system to adapt to the environment.

Calmodulin Affects Sensitization of Drosophila melanogaster Odorant Receptors

open access: yesFrontiers in Cellular Neuroscience, 2016
Flying insects have developed a remarkably sensitive olfactory system to detect faint and turbulent odor traces. This ability is linked to the olfactory receptors class of odorant receptors (ORs), occurring exclusively in winged insects.

Antennal and abdominal transcriptomes reveal chemosensory gene families in the coconut hispine beetle, Brontispa longissima

open access: yesScientific Reports, 2017
Antennal and abdominal transcriptomes of males and females of the coconut hispine beetle Brontispa longissima were sequenced to identify and compare the expression patterns of genes involved in odorant reception and detection.

Conflicting adaptations in an inhibitory feedback circuit

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We studied activity‐dependent adaptation in the fruit fly Drosophila’s memory centre, the mushroom body. Here, excitatory Kenyon cells (KCs) receive feedback inhibition from the anterior paired lateral (APL) neuron. When KCs are artificially overactivated for 24 h, both KCs and APL reduce their sensitivity to excitation (‘↓ Exc’,

Testing odorant-receptor interaction theories in humans through discrimination of isotopomers

open access: yesJournal of Biological Research, 2017
Odour reception takes place on the olfactory receptor neuron membrane, where molecular receptors interact with volatile odorant molecules. This interaction is classically thought to rely on chemical and structural features of the odorant, e.g.
