IC₅₀ values for PF956980 and PF1367550 on IFNγ and IFNγ+TNFα-stimulated release of CXCR3 chemokinesCXCL9, CXCL10 and CXCL11 from human primary airway epithelial cells.

Human primary airway epithelial cells were pre-treated for 1h in the presence of either PF956980 or PF1367550 prior to stimulation for 20h in the absence or presence of IFNγ (10ng/ml) or IFNγ+TNFα (10ng/ml). After this time, media was harvested and the concentrations of CXCL9, CXCL10 and CXCL11 measured by ELISA. Data are presented as mean±SEM, n = 13.
