Outline of Final Research Achievements |
In this study, I investigated the role of the 5-HT3 receptor in bladder function. First, I revealed that 5-HT3 receptors were expressed in the course of micturition reflex abundantly. In this process, I found 5-HT3 receptor-positive cells in bladder muscular layer. These cells were regarded as ganglionic neurons of parasympathetic nerves. These results suggested that the 5-HT3 receptor has significant roles for the bladder function. Next, I performed functional analysis. I revealed that 5-HT3 receptor agonist decreased mouse bladder volume. Therefore, the 5-HT3 receptor was suggested to be associated with the pathological condition of the overactive bladder.
