We previously demonstrated that RSV-specific memory CD8 T cells efficiently reduce lung viral titers following a secondary RSV infection in M282-immunized mice.22 To determine whether RSV-specific neutralizing antibodies contribute to early viral clearance in M282-immunized mice, we evaluated lung viral titers on days 2 and 4 post infection (p.i.)by plaque assay. The gene discussed is CD8A; the disease is infection.
