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’,

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.

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.

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 749-777, April 2026.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

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.

Molecular bases of insect odorant receptor function: specificity and evolution

open access: yesBiological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Amino acid coevolution reveals three-dimensional structure and functional domains of insect odorant receptors

open access: yesNature Communications, 2015
Insect odorant receptors (ORs) comprise an enormous protein family that translates environmental chemical signals into neuronal electrical activity.

Beyond Modeling: All-Atom Olfactory Receptor Model Simulations

open access: yesFrontiers in Genetics, 2012
Olfactory receptors (ORs) are a type of GTP-binding protein-coupled receptor (GPCR). These receptors are responsible for mediating the sense of smell through their interaction with odor ligands. OR-odorant interactions marks the first step in the process

Effect of Heat Treatment on the Flavor Characteristics of Vacuum Freeze‐Dried Pacific White Shrimp (Litopenaeus vannamei)

open access: yeseFood, Volume 7, Issue 2, April 2026.
A post‐freeze‐drying heat treatment at 150°C optimizes shrimp flavor by boosting umami compounds and generating roasted aromas via the Maillard reaction. This strategy successfully bridges the texture‐flavor trade‐off, enabling premium ready‐to‐eat shrimp products.

Molecular profiling of activated olfactory neurons identifies odorant receptors for odors in vivo

open access: yesNature Neuroscience, 2015
The mammalian olfactory system uses a large family of odorant receptors (ORs) to detect and discriminate amongst a myriad of volatile odor molecules. Understanding odor coding requires comprehensive mapping between ORs and corresponding odors.
