FIG. 4.
RSV-specific antibody responses in treated mice. RSV-specific IgG1 or IgG2a antibody responses in siRNA- or PBS-treated mice were determined at days 2, 6, 8, and 10 p.i. in mice challenged with 106 PFU of RSV/A Long. The data are presented as the mean ELISA OD ± the SE from n = five mice/treatment/time point in three separate experiments.
