The aim of this work was to investigate the effect of <jats:italic>C. trachomatis<\/jats:italic> serovar E on immortalized normal human urethral epithelial cells and on immortalized normal adult human prostate epithelial cells with regard to chlamydial growth and secretion of cytokines. After infection, these epithelial cells were assessed for their support of chlamydial growth in comparison with HeLa cells, and cytokine levels in cell culture supernatants were determined by ELISA. Although the male-derived epithelial cells supported growth of chlamydiae, the best growth was seen in HeLa cells. In contrast to prostate epithelial cells, the urethral epithelial cells released much larger quantities of interleukin 1<jats:italic>\u03b1<\/jats:italic> (IL-1<jats:italic>\u03b1<\/jats:italic>) following infection, whereas both IL-6 and IL-8 were produced in larger quantities by infected prostate cells. At 7 days post-infection, HeLa cells consistently produced large quantities of all three cytokines. In conclusion, the male-derived cell lines were shown to support the invasion of <jats:italic>C. trachomatis<\/jats:italic> and initiate a proinflammatory response to infection. From <jats:italic>in vitro<\/jats:italic> studies the suggestion that high levels of IL-6 could be a possible marker for chlamydial prostatitis is confirmed. Although not as marked a change, it is also suggested that higher IL-8 levels could be associated more with infection of the prostate than the urethra. Differential cytokine production by different male-derived epithelial cells could help determine the site of chlamydial infection and help in the study of pathogenesis.<\/jats:p>","DOI":"10.1099\/jmm.0.47241-0","type":"journal-article","created":{"date-parts":[[2007,7,20]],"date-time":"2007-07-20T17:52:59Z","timestamp":1184953979000},"page":"1025-1032","source":"Crossref","is-referenced-by-count":34,"title":["Interaction
