Sugar detection in 3D: Structure of an insect gustatory receptor. [PDF]
The insect gustatory receptors (Grs) are one of the largest families of ion channels in the animal kingdom. Frank et al.1 unveil the structure of a fructose-sensing Gr and provide insight into its function.

Light and hydrogen peroxide inhibit C. elegans feeding through gustatory receptor orthologs and pharyngeal neurons [PDF]
SUMMARY While gustatory sensing of the five primary flavors (sweet, salty, sour, bitter, and savory) has been extensively studied, pathways that detect non-canonical taste stimuli remain relatively unexplored. In particular, while reactive oxygen species

Avoiding DEET through Insect Gustatory Receptors [PDF]
DEET is the most widely used insect repellent worldwide. In Drosophila olfactory receptor neurons (ORNs), DEET is detected through a mechanism employing the olfactory receptor, OR83b. However, it is controversial as to whether ORNs respond directly to DEET or whether DEET blocks the response to attractive odors.

Antennal Transcriptome Profiling Reveals Gustatory Receptors Associated with Pollen Foraging Preferences in Apis mellifera [PDF]
Gustatory perception in honeybees is a key determinant of foraging decisions and pollen source selection. However, the molecular mechanisms underlying this sensory discrimination remain poorly understood.

A cnidarian homologue of an insect gustatory receptor functions in developmental body patterning
Insect gustatory and odorant receptors (GRs and ORs) form a superfamily of novel transmembrane proteins, which are expressed in chemosensory neurons that detect environmental stimuli.

Taste receptor downregulation in diet-induced obesity reveals circumvallate papillae-specific taste-inflammatory networks [PDF]
IntroductionBeyond their role in chemosensory perception, taste receptors function as metabolic regulators extra-orally. While decreased taste receptor expression in gustatory tissue is linked to obesity-associated inflammation, we tested the hypothesis ...

Plant insecticide L-canavanine repels Drosophila via the insect orphan GPCR DmX. [PDF]
For all animals, the taste sense is crucial to detect and avoid ingesting toxic molecules. Many toxins are synthesized by plants as a defense mechanism against insect predation.

Chemosensory detection of aversive concentrations of ammonia and basic volatile amines in insects
Summary: Basic volatiles like ammonia are found in insect environments, and at high concentrations cause an atypical action potential burst, followed by inhibition in multiple classes of olfactory receptor neurons (ORNs) in Drosophila melanogaster ...

Stimulation of the gerbil's gustatory receptors by monosaccharides [PDF]
The gustatory responses of the Mongolian gerbil were tested with a large number of monosaccharides. Electrophysiological methods were used to record from the chorda tympani nerve. Methyl glycosides which have structural features in common with sucrose are the most effective monosaccharides for eliciting a neural response.
