A series of murine macrophage cell lines was assayed for killing of B and T lymphocytic and myeloid tumor targets by radiolabel release at effector:target ratios of 20:1. One group of lines was inactive in all assays. Another group of lines showed moderate spontaneous cytotoxicity to lymphoid tumors that was greatly enhanced by inclusion of antibody, lipopolysaccharide, or phorbol myristate ace...
