Abstract
Vallate taste buds in the guinea-pig tongue were immunohistochemically investigated with regard to the colocalization of gustducin with calbindin-D28K (=spot 35 protein) and type III inositol triphosphate receptor (IP(3)R-3) in order to characterize gustducin-immunoreactive cells. Individual taste bud cells ranged from totally immunopositive to totally immunonegative for these three molecules. Among the immunoreactive cells, gustducin-immunoreactive cells were divided into two cell populations: one immunopositive and the other immunonegative for calbindin-D28K. Applying our previous data to the present results, the former cells should belong to Type III cells designated by electron microscopy. This finding provides new evidence regarding the taste bud types of cells expressing gustducin in the guinea pig.
期刊介绍：
The Archives of Histology and Cytology provides prompt publication in English of original works on the histology and histochemistry of man and animals. The articles published are in principle restricted to studies on vertebrates, but investigations using invertebrates may be accepted when the intention and results present issues of common interest to vertebrate researchers. Pathological studies may also be accepted, if the observations and interpretations are deemed to contribute toward increasing knowledge of the normal features of the cells or tissues concerned. This journal will also publish reviews offering evaluations and critical interpretations of recent studies and theories.
