Homograft Target Cells: Specific Destruction in vitro by Contact Interaction with Immune Macrophages

Specific adherence and mutual immunologic destruction occurred after contact in vitro of immune peritoneal macrophages from C57BI/6K mice with homograft target cells from A/Jax mice. Cell destruction apparently resulted from a nonphagocytic mechanism involving cell contact rather than humoral antibody. Cell destruction was determined by a plaque technique with either immunecells or target cells as monolayers.
