PG - 243-248 LID - 10.1007/s10753-020-01326-6 [doi] AB - Chronic prostatitis/chronic pelvic pain syndromes (CP/CPPS) is a clinical tricky problem due to its enigmatic etiology, low cure rate, and high recurrence rate. The research on its pathogenesis has never stopped. In this experimental autoimmune prostatitis (EAP) model, male C57BL/6 mice were subcutaneously immunized with prostate extracts in an adequate adjuvant. For mice in the antibody intervention group, anti-T2 polyclonal antibodies were intraperitoneally injected during the induction of EAP. Animals were periodically monitored for pelvic pain. Hematoxylin and eosin staining was used to assess prostate inflammation. Tumor necrosis factor-alpha (TNF-alpha) levels in serum were measured by ELISA kits. The immunized animals developed prostatitis as a consequence of the immune response against prostate antigens. Pelvic pain thresholds were gradually decreased and TNF-alpha expression significantly increased. T2 plays an important role in the disease since polyclonal antibodies to T2 greatly ameliorated symptoms in animals induced for EAP. T2 peptide may represent the major autoantigen epitope in EAP, which could serve for a better understanding of the etiology of CP/CPPS.
