Differential proteins in the prostate fluid with abnormal lecithin bodies and immunologic mechanism of chronic prostatitis patients].

To study the protein changes in the prostate fluid with abnormal lecithin bodies, and explore their relationship with the pathogenesis of chronic prostatitis. Using the tandem mass tag (TMT) technology, we identified differential proteins in the prostate fluid with abnormal lecithin bodies in normal males and analyzed their biological functions by GO functional annotation and KEGG pathways. Totally, 377 differential proteins were identified, 238 up-regulated and the other 139 down-regulated, and 8 of the top 20 significant differential proteins were related to inflammation and immune regulation. In the top 30 of the 1 011 items enriched by GO annotation, 5 were related to immune function and 3 to inflammatory response, and of the 251 KEGG pathways, 9 were involved in inflammation and immune regulation. Changes in lecithin bodies lead to proteomic changes in the prostatic fluid, which is closely related to protein- and pathway-associated inflammatory response and immune disorders, as well as to the immunologic mechanism of chronic prostatitis patients, and therefore can be used as an indicator of chronic prostatitis.
