Abstract
The following passive transfer experiments evaluated the contributions of the various host responses in recovery from mousepox. (a) Immune spleen cells transferred highly efficient antiviral activity, but preinfected recipients of these cells made no detectable splenic interferon or antibody in the 24 hr interval after cell transfer. (b) Passively administered interferon was ineffective. (c) Recipients of hyperimmune serum had much more antibody than recipients of immune spleen cells but significantly less antiviral activity. (d) Immune spleen cell populations with antiviral activity contained mediators of CMI to virus antigens. (e) The antiviral activity of immune spleen cells was specific; it was inhibited by in vitro treatment with ATS, anti-light chain serum, and anti-theta ascitic fluid, but not by removal of mononuclear phagocytes from the immune population.
