Viral infection directly causes anti-viral chemokine production in a human mast cell line. LAD2 cells were stimulated with various concentrations of VSV for 24 h (a) or with VSV (MOI = 100) for the indicated times (b). The levels of mRNA for CCL5, CXCL10, CXCL11 and IL-15 were determined by quantitative PCR. The columns present the mean ± SD of 3–5 separate experiments. *p < 0.05; **p < 0.01; ***p < 0.001 compared with un-stimulated cells
