title: The recovery of mice from influenza virus infection: adoptive transfer of immunity with immune T lymphocytes.
abstract: Transfer of primary or secondary influenza-immune spleen cells to mice infected intranasally with influenza virus resulted in a significant clearance of virus from the lungs and the protection of the recipients from death. The antiviral activity was associated only with intact, viable cells and was not due to carryover of virus. The effector cell population responsible for the antiviral effect was shown to be T cells. Thus, the removal of adherent, phagocytic and Ig+ cells did not affect the antiviral activity, whereas it was destroyed with antitheta serum and complement. Antiviral activity was specific and was best expressed if the virus used to infect the recipients and to generate immune cells was the same strain. Further work will be necessary to define rigorously the role of different viral antigens in cell-mediated immune response to influenza virus infection.
