title: P815 mastocytoma cells, classical targets for cytotoxic T lymphocytes, exert natural cytotoxicity.
abstract: While investigating the tissue distribution of cytotoxic-T-lymphocyte-associated (CTLA) gene transcripts, we found that some of these could be detected in mast cells. This led us to test the cytolysis exerted by a number of mast cell populations. We briefly report here that P815 cells, classically known as excellent target cells for cytotoxic T cells, exert natural cytotoxicity toward WEHI-164 target cells.
