The role of Cajal cells in chronic prostatitis

OpenAlex English

Types of prostatitis can be defined as groups of syndromes in adult men associated with infectious and noninfectious causes characterized frequently by lower abdominal and perineal signs and diverse clinical symptoms and complications. Etiopathogenesis of chronic prostatitis is not well defined. Moreover, its treatment outcomes are not satisfactory. Presence of c-kit positive interstitial cells in human prostate is already known. It has been demonstrated that these cells can be pacemaker cells which trigger spontaneous slow-wave electrical activity in the prostate and can be responsible for the transport of glandular secretion from acinar cells into major and minor prostatic ducts and finally into urethra. In the light of all these data, when presence of a possible inflammatory pathology is thought to involve prostate that secretes and has a reservoir which drains its secretion (for prostate, prostatic urethra), two points are worth mentioning. Impairment of secretion mechanism and collection of secretion within the organ with reflux of the microbial material from its reservoir back into prostate gland. Both of these potential conditions can be explained by ductal neuromuscular mechanism, which induces secretion. We think that in this neuromuscular mechanism interstitial Cajal cells have an important role in chronic prostatitis. Our hypothesis is that curability of prostatitis is correlated with the number of Cajal cells not subjected to apoptosis.
