| Outline of Final Research Achievements |
In the gastrointestinal tract, interstitial cells of Cajal (ICCs) act as primary pacemaker cells to generate slow wave activity, and play a fundamental role in the transmission of signals from enteric neurons to smooth muscle cells. ICCs have been also identified in the urinary bladder. KIT is used as an identification marker of ICCs, and KIT-positive ICCs are located throughout the bladder wall.
They may be involved in signal transmission between smooth muscle bundles, from efferent nerves to smooth muscles, and from urothelium to afferent nerves. Not only disturbance of spontaneous contractility caused by the altered dertusor ICC signal transduction between nerves and smooth muscle cells but also disturbance of signal transduction between urothelial cells and sensory nerves via suburethelial ICC may induce overactive bladder (OAB).
The blockage of c-kit receptor may offer a new therapeutic strategy for OAB treatment, although further study will be needed.
