Our laboratory has shown that classical synapses and synaptic proteins are associated with Type III cells. Yet it is generally accepted that Type II cells transduce bitter, sweet and umami stimuli. No classical synapses, however, have been found associated with Type II cells. Recent studies indicate that the ionotropic purinergic receptors P2X2/P2X3 are(More)
We examined en face the fine structure of rat urothelium and describe here some unique subcellular features distinguishable in the various tissue layers by this technique. The most striking finding is that large, compact fibrous bundles lie in the cytoplasm at both sides of the superficial cell tight junction for the entire length around it apical surface.(More)
