Abstract

Purpose

Little is known of the etiology and pathogenesis of chronic inflammatory prostate diseases of noninfectious origin. In our experimental autoimmune rat model for chronic prostatic inflammation (CPI) we evaluated, in a time-course study, the specific cellular immune response to male accessory glands (MAG) and metabolic activity in the prostate gland. Results obtained in CPI rats were compared with data from rats immunized with kidney homogenate as well as from non-treated rats.

Materials and Methods

Specific cellular immune response against MAG antigen(s) was studied by delayed type hypersensitivity (DTH) and lymphocyte proliferation tests. The prostate 5 alpha-reductase activity was studied in prostate homogenates by thin layer chromatography (TLC).

Results

DTH values were positive in MAG treated rats sacrificed at days 7 and 28 after first immunization (FI) (p Conclusion

These data reveal that the prostatic endocrine cell destruction during CPI could be a consequence of immune/inflammatory cell mediated processes.
