Outline of Final Research Achievements

This study clarified that, in the bladder tissues, substance P (SP) upregulates cystathione-γ-lyase (CSE) via NK1, and endogenous hydrogen sulfide generated by SP/NK1/CSE pathway facilitates processing of inflammation and participates in the development and maintenance of bladder pain through the activation of Cav3.2. These results suggest that the drug targeting these signaling pathway appears to serve as novel therapeutic strategy for treatment of painful bladder diseases including interstitial cystitis.
