Drosophila Bitter Taste(s)
Most animals possess taste receptors neurons detecting potentially noxious compounds. In humans, the ligands which activate these neurons define a sensory space called "bitter". By extension, this term has been used in animals and insects to define molecules which induce aversive responses. In this review, based on our observations carried out in Drosophila, we examine how bitter compounds are ...
متن کاملHuman bitter taste perception.
Bitter taste perception is innate and induces aversive reactions. Since numerous harmful compounds, including secondary plant metabolites, synthetic chemicals, inorganic ions and rancid fats, do taste bitter, this basic taste modality may be considered as a defence mechanism against the ingestion of potential poisons. For a complete understanding of this defence mechanism it is obligatory to id...
متن کاملBitter taste induces nausea
14 other feelings such as queasiness, weakness and gastric churning (see the Supplemental Information for details). GMA is modulated by activity from pacemaker areas of the stomach. Normal GMA oscillates at 3 cycles per minute (cpm). During either physical illness or sensations of nausea, the pattern shifts and dysrhythmias (bradygastria, 1–2.5 cpm, and tachygastria, 3.75–10 cpm) increase. Fast...
متن کاملBinary Bitter-Compound Taste Interactions
The aim of this study was to determine if taste interactions occur when bitter stimuli are mixed. Eight bitter stimuli were employed: Denatonium benzoate (DB), (L-phe), Ranitidine-HCl, and Tetralone®. The first experiment constructed individual psychophysical curves for each subject (n=19) for each compound to account for individual differences in sensitivities when presenting bitter compounds ...
متن کاملThe bitter taste of infection.
The human innate immune response to pathogens is complex, and it has been difficult to establish the contribution of epithelial signaling in the prevention of upper respiratory tract infection. The prevalence of chronic sinusitis in the absence of systemic immune defects indicates that there may be local defects in innate immunity associated with such mucosal infections. In this issue of the JC...
