Beschreibung:
Two molecular mechanisms of T cell-mediated cytotoxicity, one perforin-based, the other Fas-based, have been demonstrated. To determine the extent of their contribution to T cell-mediated cytotoxicity, a range of effector cells from normal control or perforin-deficient mice were tested against a panel of target cells with various levels of Fas expression. All cytotoxicity observed was due to either of these mechanisms, and no third mechanism was detected. Thus, the perforin- and Fas-based mechanisms may account for all T cell-mediated cytotoxicity in short-term in vitro assays.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kagi, D -- Vignaux, F -- Ledermann, B -- Burki, K -- Depraetere, V -- Nagata, S -- Hengartner, H -- Golstein, P -- New York, N.Y. -- Science. 1994 Jul 22;265(5171):528-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7518614" target="_blank"〉PubMed〈/a〉
