Induction of IL-6 (A) and IL-13 (B) release from P815 cells by GM-CSF. Cells were incubated with various concentrations of GM-CSF (ng/ml) or GM-CSF with its blocking antibody (Ab, μg/ml) at 37°C for 6 and 16 h. Values shown are Mean ± SE for four separate experiments performed in duplicate. * P < 0.05 compared with the response to corresponding medium alone control.
