Gap junctions among taste bud cells in mouse fungiform papillae.
Introduction Mouse taste buds in fungiform papillae consist of ∼50 cells (TBCs; unpublished data), but only a few of them have synaptic contacts with taste nerves (Kinnamon et al., 1993; Seta and Toyoshima, 1995). Neither chemical nor electrical synapses/gap junctions have been confirmed in mammalian taste buds, though a subpopulation of TBCs expressed a variety of neurotransmitter receptors (K...
متن کاملHuman taste: response and taste bud number in fungiform papillae.
The number of basic taste qualities registered by single human fungiform papillae is correlated with the number of taste buds borne on these papillae. Multiple sensitivity was demonstrated both in single fungiform papillae and in single taste buds, with response to all four of the basic taste qualities occuring in a single taste bud.
متن کاملFunctional expression of M3, a muscarinic acetylcholine receptor subtype, in taste bud cells of mouse fungiform papillae.
Taste bud cells (TBCs) express various neurotransmitter receptors assumed to facilitate or modify taste information processing within taste buds. We investigated the functional expression of muscarinic acetylcholine receptor (mAChR) subtypes, M1-M5, in mouse fungiform TBCs. ACh applied to the basolateral membrane of TBCs elevates the intracellular Ca(2+) level in a concentration-dependent manne...
متن کاملTaste bud density in circumvallate and fungiform papillae of the bovine tongue.
Taste bud quantitation may provide useful parameters for interspecies comparisons of the gustatory system. The present study is a morphometric analysis of bovine taste papillae. Circumvallate and fungiform papillae from six bovine tongues were serially sectioned and, following staining, analyzed. Circumvallate papillae were found to have a mean volume of 3.66 +/- 2.82 mm3, a mean number of tast...
متن کاملTaste fiber responses during reinnervation of fungiform papillae.
Crushing or transecting the chorda tympani nerve of the gerbil (Meriones unguiculatus) caused ipsilateral degeneration of taste buds in the fungiform papillae. In less than two weeks some taste fibers regenerated into the tongue and formed new taste buds and receptor cells. The recovery process was evaluated electrophysiologically in 53 gerbils by acute recording proximal to the nerve injury si...
