A pair of pharyngeal gustatory receptor neurons regulates caffeine-dependent ingestion in Drosophila larvae [PDF]
Frontiers in Cellular Neuroscience, 2016 The sense of taste is an essential chemosensory modality that enables animals to identify appropriate food sources and control feeding behavior. In particular, the recognition of bitter taste prevents animals from feeding on harmful substances. Feeding

Involvement of a Gr2a-Expressing Drosophila Pharyngeal Gustatory Receptor Neuron in Regulation of Aversion to High-Salt Foods. [PDF]
Mol Cells, 2017 Regulation of feeding is essential for animal survival. The pharyngeal sense organs can act as a second checkpoint of food quality, due to their position between external taste organs such as the labellum which initially assess food quality, and the digestive tract. Growing evidence provides support that the pharyngeal sensory neurons regulate feeding,

Ionotropic Receptors Mediate Drosophila Oviposition Preference through Sour Gustatory Receptor Neurons [PDF]
Current Biology, 2017 Carboxylic acids are present in many foods, being especially abundant in fruits. Yet, relatively little is known about how acids are detected by gustatory systems and whether they have a potential role in nutrition or provide other health benefits.

Taste cells depend on axon proximity to generate presynaptic sites. [PDF]
PLoS ONEThe turnover and re-establishment of peripheral taste synapses is vital to maintain connectivity between primary taste receptor cells and the gustatory neurons which relay taste information from the tongue to the brain.

Identifying regulators of associative learning using a protein-labelling approach in Caenorhabditis elegans [PDF]
eLifeThe ability to learn and form memories is critical for animals to make choices that promote their survival. The biological processes underlying learning and memory are mediated by a variety of genes in the nervous system, acting at specific times during ...

Transcriptome Analysis and Identification of Chemosensory Genes in Leguminivora glycinivorella [PDF]
BiologyThe soybean pod borer, Leguminivora glycinivorella, is a monophagous pest that threatens soybean production. Its larvae feed concealed within pods, which limits the efficacy of conventional insecticides.

Identification and Functional Characterization of the Leg-Enriched Chemosensory Protein PxylCSP9 in Plutella xylostella (Lepidoptera: Plutellidae) [PDF]
BiologyPlutella xylostella, a major pest of cruciferous vegetables, depends predominantly on chemoreception to locate host plants. Legs are crucial in insect chemical perception, particularly during close-range and contact chemoreception. However, the molecular

Odors drive feeding through gustatory receptor neurons in Drosophila
eLife, 2022 Summary Odors are intimately tied to the taste system to aid food selection and determine the sensory experience of food. However, how smell and taste are integrated in the nervous system to drive feeding remains elusive. We show in Drosophila that odors alone activate gustatory receptor neurons (GRNs), trigger proboscis extension ...

Neurophysiological and behavioral responses of gypsy moth larvae to insect repellents: DEET, IR3535, and picaridin. [PDF]
PLoS ONE, 2014 The interactions between insect repellents and the olfactory system have been widely studied, however relatively little is known about the effects of repellents on the gustatory system of insects. In this study, we show that the gustatory receptor neuron

Escape steering by cholecystokinin peptidergic signaling
Cell Reports, 2022 Summary: Escape is an evolutionarily conserved and essential avoidance response. Considered to be innate, most studies on escape responses focused on hard-wired circuits.
