| Outline of Final Research Achievements |
Type II taste receptive cells that receive sweet, umami and bitterness do not form synapse with taste nerves, and type III taste receptive cells that accept sour taste form synapses with taste nerve. Taste information is transmitted from type III cells via serotonin. These type III cells make synapse with the taste nerve.
From the result of previous studies, type III cells have been differentiated into "ATP receptor type III cell" and "sour taste receptor type III cell". To investigate whether it is communicating system are in the "sour taste receptive" type III cells. That is, it was suggested that "sour taste receptive" type III cells did not synapse with taste nerve.
