Wiring taste receptor cells to the central gustatory system
Oral Diseases, 2018Taste receptor cells in the tongue are epithelial in nature and turnover frequently. Taste receptor cell‐associated neurons carrying bitter, sweet, or sour signals never turnover and are hardwired to specific gustatory centers in the brain. How can ever‐changing bitter or sweet receptors find never‐changing neurons that must match the specificity of ...

Finding the sweet spot of the insect gustatory receptor
StructureIn a recent issue of Nature, Gomes et al.1 utilized structural, experimental, and computational biology to investigate the ligand-gated activation of BmGr9, an insect gustatory receptor specifically tuned to D-fructose. Together with two other studies published elsewhere, they are the first to describe how sugars bind to insect gustatory receptors.

Stimulation of the Gerbil's gustatory receptors by artificial sweeteners
Brain Research, 1981Some electrophysiological and behavioral taste experiments have been undertaken to determine how the Mongolian gerbil responds to artificial sweeteners. In the electrophysiological experiment only fourteen of twenty-one sweeteners produced neural responses.

High sensitivity of minnow gustatory receptors to amino acids
Physiology & Behavior, 1981Abstract The stimulating effects of amino acids and related compounds on the gustatory receptors were studied in the Japanese minnow, Pseudorasbora parva , by recording electrical responses from the palatine nerve innervating the upper lip and the adjacent palate.

Gustatory receptors required for sensing umbelliferone in Drosophila melanogaster
Insect Biochemistry and Molecular Biology, 2015Studies of taste modality using the animal model Drosophila melanogaster have elucidated a number of uncharacterized mechanisms of sensory responses. Gustatory receptors expressed in taste organs are not only responsible for the acceptance and rejection of different foods, but are also involved in the process of selecting an oviposition site.

The cytoarchitecture of gustatory receptors from the rabbit foliate papillae
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1967The apical region of the taste bud, delimited by the stratum disjunctum of the papillary epithelium, is divided into a distal taste pore, a channel, and a proximal chamber. In addition to “fuzzy coated” microvilli, the chamber contains an amorphous dense material histochemically defined as a neutral mucopolysaccharide.

Structures and Molecular Mechanisms of Insect Odorant and Gustatory Receptors
PhysiologyInsects rely on chemoreceptors in sensory neurons to detect and discriminate various chemicals in constantly changing environments. Among the chemoreceptors, odorant receptors (ORs) and gustatory receptors (GRs) play essential roles in sensing different odorant and tastant molecules, thereby regulating insects’ physiology and behaviors such as feeding,
