Taste buds contain two types of cells that directly participate in taste transduction–receptor
(Type II) cells and presynaptic (Type III) cells. Receptor cells respond to sweet, bitter and …

Recent identification of taste receptors and their downstream signaling molecules,
expressed in taste receptor cells, led to the understanding of taste coding in the periphery …

A family of approximately 30 TAS2R bitter taste receptors has been identified in mammals.
Their genes evolved through adaptive diversification and are linked to chromosomal loci …

Despite extensive immunological characterization of the cells within taste buds, little is
known about the functional significance of the different cell types. In this study, we use taste …

Except for taste bud cells, all sensory receptor cells and neurons have been shown to
originate from neurogenic ectoderm (ie, neural tube, neural crest, or ectodermal placodes) …

In the oral cavity, taste receptor cells dedicate to detecting chemical compounds in foodstuffs
and transmitting their signals to gustatory nerve fibers. Heretofore, five taste qualities (sweet …

Major advances in the understanding of mammalian gustatory transduction mechanisms
have occurred in the past decade. Recent research has revealed that a remarkable diversity …

High voltage electron microscopy and conventional transmission electron microscopy were
used to examine the ultrastructure of foliate taste buds of mice. Computer-assisted, three …

Background Taste buds are the sensory organs of taste perception. Three types of taste cells
have been described. Type I cells have voltage-gated outward currents, but lack voltage …

Taste bud cells undergo continual turnover even in adulthood, and their average lifespan
has been estimated as approximately 10 days. However, it is not clear whether this figure …
