Effect of Oral T2 Antigen on Chronic Prostatitis/Chronic Pelvic Pain Syndrome in Mice Model

AbstractThe exact etiology and pathogenesis of chronic prostatitis (CP/CPPS) remain unclear. However, autoimmunity is a widely known theory. Precise treatment of CP/CPPS is not available. Here, we developed a new effective treatment method to prevent the occurrence of CP/CPPS. A total of 40 male C57BL/6 mice were randomly divided into four groups (n = 10):i.e., naive, model, high-dose (500  μg/ml), and low-dose (50 μg/ml) groups. High-dose and low-dose groups were orally given 0.4 ml of T2-containing soybean trypsin inhibitor (STI) at once after every 2 days for a total of 10 days. On day 10 and day 24 all the groups except naïve group were subcutaneously injected with 0.2 ml of T2 peptide along with CFA to make valid CP/CPPS models. Hematoxylin and eosin staining were used to evaluate the variation in CP/CPPS manifestation. Voiding behavior was recorded for the evaluation of urine frequencies. ELISA was used to measure the serum level of TNF-α in each group. The high- and low-dose groups of T2-containing STI displayed a reduction in urine frequencies, and inflammation, and there was a slight inflammatory infiltration as compared to the model group. In contrast, there was no difference observed in the TNF-α concentration of model as well as high- and low-dose gr oups compared to the naïve group. Our study demonstrates that oral T2-containing STI prevents CP/CPPS and provides an effective approach for the treatment of CP/CPPS.
