FIG. 3.

CCL3 expression in response to RSV infection. (A) Levels of CCL3 mRNA in whole lungs of BALB/c mice were assessed by RNase protection assays. Each mouse was tested individually (n = 4 per group). Some groups of mice had been primed 2 to 3 weeks earlier with either rVV-F, rVV-G, or rVV-βgal. Results are expressed as protected band intensity and are percentages of the intensity of the housekeeping genes L32 and GAPDH. Each data point is the mean for four animals. Error bars, standard errors. (B) CCL3 protein levels in cell-free BAL fluids from rVV-G- or rVV-F-primed and RSV-infected BALB/c mice were assessed by ELISA. The limit of detection is 15 pg/ml (dotted line).
