Altered peptide ligands trigger perforin- rather than Fas-dependent cell lysis.

Journal article

CTLs lyse Fas-expressing target cells by the concomitant action of a perforin- and a Fas-dependent mechanism. This study analyzed whether target cells pulsed with T cell antagonists and other altered peptide ligands (APLs) were susceptible selectively to only one of these two mechanisms. In vivo and in vitro activated T cells from transgenic mice expressing a TCR specific for lymphocytic choriomeningitis virus were used as effector cells. To distinguish between perforin- and Fas-dependent cyt...
