Cyclophosphamide (CP) has been widely used in the treatment of various malignancies and autoimmune diseases, but acrolein, a byproduct of CP, causes severe hemorrhagic cystitis as the major side effect of CP. On the other hand, a large amount of prostacyclin (PGI2) is produced in bladder tissues, and PGI2has been shown to play a critical role in bladder homeostasis. PGI2is biosynthesized from prostaglandin (PG) H2, the common precursor of PGs, by PGI2synthase (PTGIS) and is known to also be involved in inflammatory responses. However, little is known about the roles of PTGIS‐derived PGI2in bladder inflammation including CP‐induced hemorrhagic cystitis. Using both genetic and pharmacological approaches, we here revealed that PTGIS‐derived PGI2‐IP (PGI2receptor) signaling exacerbated CP‐induced bladder inflammatory reactions.Ptgisdeficiency attenuated CP‐induced vascular permeability and chemokine‐mediated neutrophil migration into bladder tissues and then suppressed hemorrhagic cystitis. Treatment with RO1138452, an IP selective antagonist, also suppressed CP‐induced cystitis. We further found that cystitis‐related nociceptive behavior was also relieved in bothPtgis−/−mice and RO1138452‐treated mice. Our findings may provide new drug targets for bladder inflammation and inflammatory pain in CP‐induced hemorrhagic cystitis.
