The aryl hydrocarbon receptor agonist ITE reduces inflammation and urinary dysfunction in a mouse model of autoimmune prostatitis.

Objectives: Prostate inflammation is linked to lower urinary tract dysfunction and is a key factor in chronic prostatitis/chronic pelvic pain syndrome. Autoimmunity was recently identified as a driver of prostate inflammation. Agonists of the aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor, have been used to suppress autoimmunity in mouse models of colitis, rhinitis, and dermatitis, but whether AHR agonists suppress prostate autoimmunity has not been examined.
