Abstract_ Background MHC class I-restricted CD8 cytotoxic T lymphocytes CTL are thought to play a major role in clearing virus and promoting recovery from influenza infection and disease. This has been demonstrated for clearance of influenza virus from the lungs of infected mice. However human influenza infection is primarily a respiratory mucosal infection involving the nasopharynx and tracheobronchial tree. The role of CD8 CTL directed toward the influenza nucleoprotein NP in defense against influenza virus infection at the respiratory mucosa was evaluated in two separate adoptive transfer experiments. Methods Influenza nucleoprotein NP -specific CD8 CTL were generated from splenocytes obtained from Balb c mice previously primed with influenza A Taiwan l 86 H1N1 infection or with influenza A PR 8 34 H1N1 -derived NP plasmid DNA vaccine followed by infection with A Hong Kong 68 .
