IL1B and asthma: Some cytokines elevated in subjects with asthma significantly correlated with the level of IL-8 in BAL fluids: IL1-RA (R = 0.59, p<0.01), IL-1α (R = 0.40, p<0.05), IL-6 (R = 0.68, p<0.001), IL-7 (R = 0.47, p<0.05), G-CSF (R = 0.74, p<0.0001), CCL4 (R = 0.45, p<0.05), CXCL1 (R = 0.64, p<0.01), and CXCL9 (R = 0.48, p<0.05).
