Figure 1.

Time course showing relative kinetics and release of (a) GM-CSF, (b) RANTES, (c) eotaxin and (d) IL-8 into the supernatants of human cultured airway smooth muscle cells stimulated with maximally-effective concentrations of either IL-1β (1 ng ml⁻¹) or TNFα (10 ng ml⁻¹). Points represent mean±s.e.mean of duplicate values from independent experiments using cells cultured from four different donors, cell passages 3 – 6. ^*P<0.05, ^**P<0.01, ^***P<0.001 compared to control at similar time points by Bonferroni's t-test. §P<0.01 compared to the other cytokine at similar time points by Bonferroni's t-test.
