A mouse model was developed to simulate the clinical features of chronic prostatitis/chronic pelvic pain syndrome using peptide (T). Forty C57BL/6 mice were divided into four groups of 10 mice each, averagely and randomly. Tplus aluminium hydroxide adjuvant group was given subcutaneous injection with the emulsion mixture of Tand aluminium hydroxide adjuvant, the Tgroup with T, the aluminium hydroxide adjuvant group with aluminium hydroxide adjuvant and the normal control group with 0.9/% NaCl solution. Haematoxylin andeosin staining was used to observe the inflammation of the prostate. Plasma levels of TNF-α and CRP were detected by ELISA kit. The expression of IL-1βin the prostate was investigated by immunohistochemistry. The statistical differences between the groups were compared by t test. Histopathological analyses demonstrated that prostate lesions were most severe in the group immunised with Tplus aluminium hydroxide adjuvant. Plasma levels of TNF-α and CRP were statistically elevated compared with control groups. The expression levels of IL-1β in the prostate were more obvious than control groups. Tin aluminium hydroxide adjuvant subcutaneous injection could successfully set up experimental autoimmune prostatitis in C57BL/6 mice. This murine model would be greatly beneficial to further comprehend the aetiology, pathogenesis and explicit treatment of CP/CPPS.
