[Cross reactivity of the cytotoxic lymphocytes of mice immunized with the virions of pathogenic and nonpathogenic influenza virus strains and membrane protein].

The cytotoxic activity of lymphocytes of C3HA and C3H (H-2X) mice immunized with the mouse-pathogenic A/PR8/34 (H0N1) and nonpathogenic A/Krasnodar/101/59 (H2N2) strains of influenza virus and with isolated membrane protein was studied. The sensitized lymphocytes were shown to be capable of recognizing and lysing the cells infected with homologous or heterologous virus.
