Mice maintained in our animal colony become primed to Sendai virus. This "environmental" priming is reflected in a shift in prekiller activity from the Ly 123 to Ly 23 T cell set and in increased virus-specific cytolytic activity. This transition is accompanied by the development of cytolytic activity against allogeneic targets (not expressing Sendai antigens). These findings are consistent with the view that continued stimulation of Ly 123 cells by autologous MHC antigens, associated with foreign antigens such as a virus, generate Ly 23 prekiller cells that respond to alloantigens as well as autologous cells infected with the relevant virus.
