Chronic non bacterial prostatitis is a chronic inflammatory syndrome. Its etiology and physiopathology are unclear and treatments are empirical and ineffective in most cases. Autoimmunity has been proposed as an etiology. In the present report, we investigated the impact of vitamin D receptor silencing, by use of VDR-KO NOD mice and the immune-modulating effect of the vitamin D3 analog TX527 on the development of Experimental Autoimmune Prostatitis in NOD mice. VDR-KO NOD mice developed a more aggressive form of autoimmune prostatitis characterized by a greater lymphoproliferative response against prostate antigen in vitro (6.92+/-4.77 vs. 2.47+/-0.41 21 days after disease induction, p<0.05) and higher levels of specific INFgamma secretion (471+/-6 vs. 386+/-5pg/ml, p<0.01). This was accompanied in vivo by more severe lesions and augmented mononuclear cell infiltration in the prostate gland. On the other hand, although analog-treated mice showed a significant reduction in the spleen T-cell specific proliferative response against prostate antigen in vitro, no effect on disease development was observed. We conclude that vitamin D receptor modulation holds the promise of interfering with autoimmune prostatitis. Introduction of more powerful analogs, or combinations with anti-T-cell reagents may represent therapeutic solutions for these group of patients.
