| Research Abstract |
In this study, the procedures for visualization and culture of sensory neurons innervating the urinary bladder and for culture of bladder urothelial cells have been established. In addition, the transmission of excitation in response to mechanical stimuli from one cultured urothelial cell to surrounding urothelial cells in culture system was characterized using calcium imaging techniques. Also, in order to elucidate the mechanisms underlying autonomic regulation of bladder function and detect new therapeutic target for bladder dysfunction including overactive bladder, expression of Kv4 poreforming and auxiliary subunits, which constitute A-type potassium channels that participate in the control of micturition, was clarified in C-fiber afferent neurons from L6-S1 dorsal root ganglia, which contain bladder afferent neurons.
