Cytokine induction in monocytes infected with C. pneumoniae or stimulated with LPS from E. coli. Human adherent monocytes (2 × 105/well of 24 well plates) were infected with 2 × 104 (open bars) or 2 × 103 (hatched bars) inclusion forming units of C. pneumoniae or stimulated with 1 ng/ml LPS (black bars) for 3, 6, 24, and 48 h. Medium alone served as negative control (grey bars). Mock controls did not differ from the values obtained for “medium alone”. Concentrations are expressed as mean ± SD for 3 independent experiments. *P ≤ 0.05.
