摘要: Two molecular mechanisms of T cell-mediated cytotoxicity, one perforin-based, the other Fas-based, have been demonstrated. To determine extent their contribution to a range effector cells from normal control or perforin-deficient mice were tested against panel target with various levels Fas expression. All cytotoxicity observed was due either these mechanisms, and no third mechanism detected. Thus, perforin- Fas-based may account for all in short-term vitro assays.
