The distribution of effector cells for antibody-dependent cytotoxicity is species dependent
Murine lymphoma cells were lysed by using either an allogeneic or a xenogeneic (rat) antiserum and antibody-dependent effectors from mice and rats. It was found that murine spleens were poorly antibody-dependent effectors against this target. The peritoneal cavities of mice were a good source of effectors. In rats, the spleen contained effectors, whereas adherent cells from the peritoneal cavity were comparatively ineffective. Cells from both rat and murine spleens lysed sheep erythrocytes in conjunction with an appropriate antiserum. The data emphasize that there is a difference in the antibody-dependent lysis of erythrocytes compared to nucleated mammalian cells. They also demonstrate that the distribution of antibody-dependent effectors is species dependent.
