Connexin-32 and Connexin-43 Immunoreactivity in Rodent Taste Buds
… ATP is one of the primary neurotransmitters in taste transduction. ATP release occurs from taste cells via specific hemichannels such as pannexin/connexin hemichannels (Huang et al., 2007; Romanov et al., 2007). We hypothesize that Type II (receptor) and possibly Type III (presynaptic) cells …

The Physiological Role of Serotonergic Transmission in Adult Rat Taste Buds
… of the neurotransmitter serotonin (5-HT) in the taste bud is not well understood. Serotonin was long thought to be the neurotransmitter of taste signals from taste receptor cells (TRCs) to the gustatory afferent nerves, but the surprising discovery that this transmission is actually purinergic …

Dopamine-Beta-Hydroxylase and Norepinephrine Transporter Immunoreactivity in Rat Taste Buds
<p>Of the handful of neurotransmitters modulating taste response, norepinephrine (NE) may be the least understood. Although the physiological role of NE has been tested, it is still unclear whether the rat taste bud may serve as an endogenous source of neurotransmitter or if it must be taken up …

Mosaic Analysis with Double Markers (MADM) as a Method to Map Cell Fates in Adult Mouse Taste Buds.
<p>Taste buds are chemosensory endorgans embedded in the oral epithelium composed of cells that undergo continuous replacement. Mature taste cells live on average 10-14 days and are replaced by new cells when they die. However, the mechanism by which taste cells are produced and integrated into the …

Experimental studies on the organisation of the gustatory systems of the carp (Cyprinus carpio)
… associated with the presence of large numbers of taste buds located respectively, within the oropharynx, especially on the palatal organ, and on the body surface, in particular the barbels.

Gross and Microscopic Observations on the Lingual Structure of the West Indian Manatee (Trichechus manatus latirostris)
… on the caudal region of the tongue, contained taste buds embedded in the epidermis. Glands within the foliate papillae were mostly mucous, though some seromucous glands were evident. Throughout the tongue, striated muscle was abundant below the epidermis. Blood vessels, lymph channels, and …

Peripheral Taste System in Inbred Mouse Strains
Taster and non-taster mice strains have been used extensively in animal taste research. Inbred mouse strains C57 and FVB have been proposed to be tasters, where as strains 129 and Balb/C are classified as non-tasters. Therefore, evaluating the peripheral taste system in these mice is of great …

La percezione del gusto amaro nell’uomo: la sensibilità gustativa al 6-n-propiltiouracile (PROP) come marker della variabilità individuale con implicazioni fisiologico-nutrizionali
… differences in the salivary proteins involved in taste function. Among them, the enzyme Zn dependent gustin, a trophic factor of taste buds. We investigated the possible association of PROP taste phenotype with TAS2R38 haplotypes, gustin gene polymorphism rs2274333 (A/G), salivary …

Aceitação e intenção de compra do queijo tipo coalho de búfala e de vaca no município de Areia - PB
… the dressing room and then the sample QCB. The taster evaluated samples and tagged as their affection for the product offered, scoring points in a seven-point hedonic scale, ranging from "I really liked the disliked a lot" and the test of intention to purchase. Averages were calculated and then …

The roles of FGF and Wnt signaling during maxillary barbel regeneration in the Zebrafish (Danio rerio).
… organ that contains skin, glands, pigment cells, taste buds, nerve fibers, blood vessels and a putative lymphatic. Like other zebrafish organs, the maxillary barbel can regenerate most of its tissues after amputation. However, little is known about the molecular mechanisms that control this …

Neuroanatomical Maps and Taste Reactivity to Sweet, Umami, and Bitter Taste in the PBN of C57BL/6J Mice
… Humans can distinguish at least five different taste qualities, sour, salty, bitter, sweet, and umami (the savory taste of certain amino acids). In neuroscience research, behavioral testing is used to measure the ability of rodents (including inbred mice) to discriminate between the different …

Identifying Novel Molecular Mechanisms Underlying Lateral Line Organ Development in Sterlet
… line structures such as gill filaments and taste buds.) I explored the Bmp signalling pathway in the most depth. I identified lateral line organ expression of genes encoding two ligands (Bmp5, Bmp4), an activin type II receptor (Acvr2a) that can complex with type I Bmp receptors, and two …

A Behavioral and Anatomical Analysis of Conditioned Taste Aversion in C57BL/6J and DBA/2J Mice
<p>Conditioned taste aversion (CTA) has been commonly used as a model of learning and memory. Traditionally, CTA approaches have used a paradigm that follows the model of classical conditioning. This involves presentation of a novel tastant, such as sucrose (conditioned stimulus, CS), followed by …

Intraspecific Variation Among Emerald Shiners (Notropis atherinoides) of the Missouri River
… (counts of vertebrae, fin rays, scales, teeth, taste buds, etc.) are governed by genotype, but can vary during embryonic development in response to temperature, sunlight, and stress. Naturally, a predictable longitudinal gradient or random insignificant variation should be seen. When conditions …

Sensitivity to chemical stimuli plays a fundamental role in the food preferences. Examples in the evolutionary scale: 1. Role of the walking leg chemoreceptors in the red swamp crayfish Procambarus Clarkii 2. PROP bitter taste sensitivity and its nutritional implications in Humans
… for crayfish population control programs. Taste sensitivity varies greatly in humans, influencing eating behavior and therefore may play a role in body composition. PROP bitter taste sensitivity is the most studied example of the individual variability of taste sensitivity. Some studies …
