Effects of TLR2 and TL4 ligation on cytokine production by human prostate cancer cell lines. Prostate cancer cells were treated with LPS or LTA and concentrations of IL-6 (A) and IL-8 (B) were measured in culture supernatants by ELISA. Each bar represents the mean ± SD of three independent experiments and each test was done in triplicate. In each cell line, the data were compared to vehicle-treated (control) cells. c: p < 0.001, b: p < 0.01, a: p < 0.05.
