Development of cytotoxic cell activity in naive and tolerant CBA mice after immunization with 2 weekly transfusions of untreated PBMCs from BALB/c mice.
Target cells were ConA-stimulated lymphoblasts from BALB/c mice and labeled with 3H-thymidine. (A) Results of cytotoxic activity of spleen T cells from naive CBA mice with (▪) and without (■) immunization of BALB/c PBMCs. (B) Results of cytotoxic activity of spleen T cells from tolerant CBA mice with (▴) and without (▵) immunization of BALB/c PBMCs. Each value is a mean of triplicate incubations.
