Insulin-Like Growth Factors Are Expressed in the Taste System, but Do Not Maintain Adult Taste Buds.
Growth factors regulate cell growth and differentiation in many tissues. In the taste system, as yet unknown growth factors are produced by neurons to maintain taste buds. A number of growth factor receptors are expressed at greater levels in taste buds than in the surrounding epithelium and may be receptors for candidate factors involved in taste bud maintenance. We determined that the ligands...

متن کاملImmunohistochemical Analysis of Human Vallate Taste Buds.
The morphology of the vallate papillae from postmortem human samples was investigated with immunohistochemistry. Microscopically, taste buds were present along the inner wall of the papilla, and in some cases in the outer wall as well. The typical taste cell markers PLCβ2, GNAT3 (gustducin) and the T1R3 receptor stain elongated cells in human taste buds consistent with the Type II cells in rode...
متن کاملAge does not affect numbers of taste buds and papillae in adult rhesus monkeys.
Taste buds and papillae in tongues of rhesus monkeys were examined and counted to determine if there are age-related differences in general morphology or numbers of receptor organs. Tongues from 15 monkeys in five groups aged 4-31 years were studied with light microscopy. Fungiform, circumvallate, and foliate papillae were examined and taste buds in each papilla type were counted. Numbers of pa...
متن کاملSynaptic connections in developing and adult rat taste buds.
Synaptic connections in rat taste buds closely resemble synapses found in the CNS. Taste bud synapses are characterized by parallel, apposed, thickened membranes that are separated by a cleft ranging from 16 to 30 nm. The putative synaptic vesicles are of two types: small, clear vesicles (40–70 nm) and large, dense-cored vesicles (90–120 nm). The small, clear vesicles predominate at most synaps...
