SP600125 inhibits L. pneumophila -induced IL-8 expression and secretion. Jurkat cells were pretreated with the indicated concentrations of SP600125 for 1 h prior to L. pneumophila Corby infection and subsequently infected with Corby (MOI, 100:1) for 4 h (A) and 24 h (B). IL-8 mRNA expression on harvested cells was analyzed by RT-PCR (A) and the supernatants were subjected to ELISA to determine IL-8 secretion (B). Data are mean ± SD of three experiments. (C) Jurkat cells were pretreated with or without SP600125 (20 μM) for 1 h prior to L. pneumophila Corby infection and subsequently infected with Corby (MOI, 100:1) for the indicated times. Cell lysates were prepared and subjected to immunoblotting with the indicated antibodies. Data in (A) and (C) are representative examples of three independent experiments with similar results.
