Splenocytes from influenza-primed mice do not kill RSV-infected targets. Spleens from RSV- or influenza-infected mice were removed after 14 d and disrupted to a single cell suspension. After 5 d in the presence of 2 PFU/cell of RSV or 1 HA unit of influenza virus, remaining cells were assessed for cytotoxic activity. RSV-immune mice effectively killed RSV-infected targets (♦). Influenza-immune splenocytes similarly killed influenza (▴) but not RSV-infected (▪) targets. (B) Influenza tetramer–positive cells were purified from the lung and mediastinal lymph nodes of 10 influenza-infected and RSV-challenged mice using avidin-coated magnetic beads and MACS. A cytotoxicity assay with influenza- (•) or RSV- (⋄) infected P815 cells was then performed. Spontaneous release has been subtracted from all results and never exceeded 10% of maximal chromium release.
