Disc Electrophoresis of Extracts from the Taste Buds Located in Circumvallate Papillae of Rat Tongues
The epithelium of the circumvallate papillae of rat tongues was stripped off by treatment with 0.005% elastase in a state when many taste buds were present. The taste buds were isolated from the stripped epithelium by further treatment with 0.005% elastase and 0.08% trypsin. A protein which was thought to be characteristic of taste buds was found from semimicro disc polyacrylamide gel electroph...
متن کاملExocytotic release of neurotransmitter substances from nerve endings in the taste buds of rat circumvallate papillae.
Exocytotic release of neurotransmitters from nerve endings was demonstrated ultrastructurally in the taste buds of rat circumvallate papillae by stimulation of high K+ and Ca2+ Ringer perfusion and application of tannic acid-Ringer incubation (TARI) method. Omega-shaped images of large cored vesicles and small clear vesicles, indicating exocytotic release of their contents, were found only in t...
متن کاملA2BR Adenosine Receptor Modulates Sweet Taste in Circumvallate Taste Buds
In response to taste stimulation, taste buds release ATP, which activates ionotropic ATP receptors (P2X2/P2X3) on taste nerves as well as metabotropic (P2Y) purinergic receptors on taste bud cells. The action of the extracellular ATP is terminated by ectonucleotidases, ultimately generating adenosine, which itself can activate one or more G-protein coupled adenosine receptors: A1, A2A, A2B, and...

متن کاملExpression of phospholipase C-beta4 in rat circumvallate taste buds.
The heteromer of T1R1 and T1R3 and taste-mGluR4 function as receptors for glutamate (umami) taste sensation (Chaudhari et al., 2000; Nelson et al., 2002). Metabotropic glutamate receptor type 1 (mGluR1α) is expressed in taste receptor cells in rat gustatory papillae (Toyono et al., 2003). It has been known that mGluR1α couples preferentially to an α-subunit of the Gαq family, leading to activat...
