Mechanism of Acetic Acid Gustatory Repulsion in Drosophila [PDF]
Cell Reports, 2019 Summary: The decision to consume or reject a food based on the degree of acidity is critical for animal survival. However, the gustatory receptors that detect sour compounds and influence feeding behavior have been elusive.

Physiology of gustatory receptor neurons in the fruit fly (Drosophila melanogaster)
, 2016 In most animals including insects, ingestion is preceded by a close examination of the food, for example in order to detect the presence of potentially noxious chemicals. This detection involves specialized gustatory cells, which are generally described as sensitive to “bitter” tastes. Using electrophysiology and behavioral observations, we studied how

Primary Culture of Gustatory Receptor Neurons from the Blowfly, Phormia regina [PDF]
Chemical Senses, 2006 Flies provide a powerful model system for exploring signaling systems in gustatory receptor neurons (GRNs). To elucidate the cellular and molecular bases of these signaling systems, we sought to develop techniques to dissociate GRNs. We developed a primary culture of GRNs isolated from the labella of the blowfly, Phormia regina, 4-5 days after pupation.

Rat Gustatory Neurons in the Geniculate Ganglion Express Glutamate Receptor Subunits [PDF]
Chemical Senses, 2004 Taste receptor cells are innervated by primary gustatory neurons that relay sensory information to the central nervous system. The transmitter(s) at synapses between taste receptor cells and primary afferent fibers is (are) not yet known. By analogy with other sensory organs, glutamate might a transmitter in taste buds. We examined the presence of AMPA

Opposing chemosensory functions of closely related gustatory receptors
eLife, 2023 In the fruit fly Drosophila melanogaster, gustatory sensory neurons express taste receptors that are tuned to distinct groups of chemicals, thereby activating neural ensembles that elicit either feeding or avoidance behavior.

Midline crossing by gustatory receptor neuron axons is regulated byfruitless, doublesexand the Roundabout receptors [PDF]
Development, 2010 Although nervous system sexual dimorphisms are known in many species, relatively little is understood about the molecular mechanisms generating these dimorphisms. Recent findings in Drosophila provide the tools for dissecting how neurogenesis and neuronal differentiation are modulated by the Drosophila sex-determination regulatory genes to produce ...

Drosophila TRPA1 channel mediates chemical avoidance in gustatory receptor neurons [PDF]
Proceedings of the National Academy of Sciences, 2010 Mammalian sweet, bitter, and umami taste is mediated by a single transduction pathway that includes a phospholipase C (PLC)β and one cation channel, TRPM5. However, in insects such as the fruit fly, Drosophila melanogaster , it is unclear whether different tastants, such as bitter compounds, are sensed in gustatory ...

The gustatory system influences "Drosophila" lifespan [PDF]
, 2011 The lifespan of an organism is affected by the complex interplay between genetic and environmental factors. In C. elegans, this interaction between genes and environment is mediated by the sensory system.

Input-driven components of spike-frequency adaptation can be unmasked in vivo [PDF]
, 2004 Spike-frequency adaptation affects the response characteristics of many sensory neurons, and different biophysical processes contribute to this phenomenon.
