A broadly tuned mouse odorant receptor that detects nitrotoluenes

, 2012
Mammals employ large numbers of odorant receptors to sample and identify volatile chemicals in the environment. These receptors are thought to vary not only in specificity for particular odorants, but also in breadth of tuning.

Iroquois complex genes induce co-expression of rhodopsins in Drosophila. [PDF]

, 2008
The Drosophila eye is a mosaic that results from the stochastic distribution of two ommatidial subtypes. Pale and yellow ommatidia can be distinguished by the expression of distinct rhodopsins and other pigments in their inner photoreceptors (R7 and R8),

Comparing the Expression of Olfaction-Related Genes in Gypsy Moth (Lymantria dispar) Adult Females and Larvae from One Flightless and Two Flight-Capable Populations

Frontiers in Ecology and Evolution, 2017
In insects, flight and sophisticated olfactory systems go hand in hand and are essential to survival and evolutionary success. Females of many Lepidopteran species have secondarily lost their flight ability, which may lead to changes in the olfactory ...

Retronasal Olfactory Function After Olfactory Training: A Prospective Single‐Arm Study

Clinical Otolaryngology, EarlyView.
ABSTRACT Background Retronasal olfaction is essential for aroma perception. Its impairment in individuals with olfactory dysfunction (OD) negatively affects dietary behaviour and quality of life. Regular exposure to odours in a form of olfactory training (OT) is used to rehabilitate the sense of smell.

Antennal Transcriptome Analysis of the Chemosensory Gene Families From Trichoptera and Basal Lepidoptera

Frontiers in Physiology, 2018
The chemosensory gene families of insects encode proteins that are crucial for host location, mate finding, oviposition, and avoidance behaviors. The insect peripheral chemosensory system comprises odorant receptors (ORs), gustatory receptors (GRs ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet

The FEBS Journal, EarlyView.
C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...

Toward a pharmacology of odor receptors and the processing of odor images

The Journal of Steroid Biochemistry and Molecular Biology, 1991
Odor molecules may be considered as molecular ligands which bind to receptors in the olfactory sensory neurons to give rise to the sensory response. Binding studies in whole sensory epithelia suggest that the receptors also bind muscarinic cholinergic antagonists.

Odor Identification Quantitatively by Odorant Receptor Vectors

, 2022
Abstract Background: Odors are perceived by individuals through sensation, memory, experience, etc., and mainly subjective and qualitative evaluation has been performed until now. On the other hand, since Buck et al. succeeded in cloning the odorant receptor in 1991, researchers have shown interest in olfaction system, and molecular biology ...

Expression of Tas1 taste receptors in mammalian spermatozoa [PDF]

, 2012
Background: During their transit through the female genital tract, sperm have to recognize and discriminate numerous chemical compounds. However, our current knowledge of the molecular identity of appropriate chemosensory receptor proteins in sperm is ...
