Various subcellular bacterial fractions are known to enhance immune responses and serve as potent adjuvants. Muramyl dipeptide (MDP), a synthetic adjuvant mimicking a component of mycobacterial cell walls, enhances humoral immunity to soluble antigens and can increase macrophage cytotoxicity toward mastocytoma cells in vitro. In the present study MDP was(More)
The FBL-3 lymphoma cell line caused impaired antibody formation in vivo when injected into mice intraperitoneally, and in vitro when added to normal syngeneic spleen cells immunized in vitro with sheep erythrocytes. Immunosuppression occurred only when intact viable tumor cells were cocultivated with the normal spleen cells. As few as 10(5) FBL-3 cells,(More)
