| Research Abstract |
This study suggests that, in the cyclophosphamide-induced cystitis model, TRP channel-mediated early inflammatory response triggers induction of expression of the hydrogen sulfide synthetic enzyme, leading to increase in the generation of hydrogen sulfide in bladder tissue. The generated hydrogen sulfide induces bladder pain through the T-type Ca^<2+> channels and aggravates the inflammatory symptom. These findings raise the possibility that hydrogen sulfide synthetic enzyme and/or T-type Ca^<2+> channels can be new target molecules for the development of therapeutic agents against cystitis and bladder pain.
