FIG. 1.

CD8⁺ T and NK cells in CD1d^−/− mice following RSV infection. CD1d^+/+ and CD1d^−/− mice on 129×B6, B6, and BALB/c genetic backgrounds were infected intranasally with 10⁷ PFU of live RSV. Recruitment of CD8⁺ T cells (A) and NK cells (B) to the lung was examined at the indicated time points after RSV infection by cell surface staining and FACS analysis. The data are the means ± standard errors of the means (SEMs); n = 8 for 129×B6 mice (three experiments combined), n = 9 for B6 mice (two experiments combined), and n = 18 for BALB/c mice (four experiments combined) for each time point shown.
