Induction of IL-6 and IL-8 in T24 and 5637 by LPS stimulation. a Cells were stimulated with log increments of LPS between 0 ng/ml and 1000 ng/ml, the supernatant levels of IL-6 and IL-8 were determined 6 h after incubation with LPS by ELISA, *p < 0.05 versus 0 ng/ml. b Cells were stimulated with 100 ng/ml LPS for 24 h, the supernatant levels of IL-6 and IL-8 measured by ELISA at the indicated times, *p < 0.05 versus 0 h. Experiments were performed at least three times in triplicate. Data represent the means ± SEM
