Immunoreactivity of IL-17A and IL-17RA in cystitis, polyp and bladder cancer tissues. a Representative photomicrographs of IL-17A expression in bladder sections from subjects with cystitis (n = 23), polyp (n = 6) and bladder cancer (n = 80) (original magnification × 10 and 20). b Quantitative analysis of IL-17A expression area of bladder sections (% of whole sections). c Representative photomicrographs of IL-17RA expression in bladder sections from cystitis, polyp and cancer. d Quantitative analysis of IL-17RA expression area of bladder sections (% of whole sections). Data are expressed as the mean ± SEM. Arrows show examples of positively stained cells. The scale bar means 100 μm
