Lack of Pattern Separation in Sensory Inputs to the Olfactory Bulb during Perceptual Learning. [PDF]

, 2017
Recent studies revealed changes in odor representations in the olfactory bulb during active olfactory learning (Chu et al., 2016; Yamada et al., 2017).

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, Volume 35, Issue 3, Page 270-283, June 2026.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Phylogenetic history shapes the composition of floral scents in a specialized pollination mutualism

New Phytologist, Volume 250, Issue 5, Page 3428-3443, June 2026.
Summary Most studies of the chemical ecology of plant–pollinator interactions emphasize the role of pollinator‐mediated selection in shaping floral scent composition. Nevertheless, phylogeny may constrain the metabolic pathways underlying these profiles, thereby influencing the evolutionary trajectory of the emitted signals.

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioral response dynamics to pheromone in Drosophila [PDF]

, 2012
Conclusions: Our study presents evidence that Est-6 plays a role in the physiological and behavioral dynamics of sex pheromone response in Drosophila males and supports a role of Est-6 as an odorant-degrading enzyme (ODE) in male antennae.

Inhibition of Anopheles gambiae Odorant Receptor Function by Mosquito Repellents*

Journal of Biological Chemistry, 2015
Background: The mode of action of insect repellents on odorant receptor (OR) function remains unclear. Results: Anopheles gambiae OR function in vitro is inhibited by specific repellents.

Transition Metal‐Catalyzed Functionalization of Nonallylic Alkenyl Alcohols via Chain‐Walking Strategies

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
This minireview outlines recent advances in chain‐walking reactions of nonallylic alkenyl alcohols catalyzed by various transition metals, including palladium, ruthenium, rhodium, iridium, and nickel. Furthermore, the corresponding reaction mechanisms are discussed.

Molecular basis for odorant receptor tuning: a short C‐terminal sequence is necessary and sufficient for selectivity of mosquito Or8

Insect molecular biology (Print), 2015
A birth‐and‐death evolutionary model for odorant receptor gene repertoires presumes the creation of repertoires with the capacity for high‐level diversity and rapid ligand specificity change.

Early and Sustained Improvements in Sense of Smell With Tezepelumab Treatment in Patients With Chronic Rhinosinusitis With Nasal Polyps (WAYPOINT)

International Forum of Allergy &Rhinology, Volume 16, Issue 5, Page 484-494, May 2026.
ABSTRACT Background Loss of smell is a principal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP), affecting health‐related quality of life and posing a safety hazard. Methods WAYPOINT (NCT04851964), a phase 3, multicenter trial in adults with uncontrolled CRSwNP, randomized patients 1:1 to receive tezepelumab 210 mg or placebo ...

Genomic content of chemosensory genes correlates with host range in wood-boring beetles (Dendroctonus ponderosae, Agrilus planipennis, and Anoplophora glabripennis)

BMC Genomics, 2019
Background Olfaction and gustation underlie behaviors that are crucial for insect fitness, such as host and mate selection. The detection of semiochemicals is mediated via proteins from large and rapidly evolving chemosensory gene families; however, the ...

A Conserved Odorant Receptor Detects the Same 1-Indanone Analogs in a Tortricid and a Noctuid Moth

Frontiers in Ecology and Evolution, 2015
Odorant receptors (ORs) interface animals with airborne chemical signals. They are under strong selection pressure and are therefore highly divergent in different taxa. Yet, some OR orthologs are highly conserved.
