Killing of SKW6 B lymphoblastoid cells by anti-CD95 antibody or by RIP–CD95L⁺ adult islet β cells. SKW6 B cells are killed by increasing concentrations of anti-CD95 antibody (left side of graph) or by incubation with RIP–CD95L⁺ adult islet cells expressing different amounts of transgenic CD95L (right side of graph). A CD95–Fcγ fusion protein that binds to and blocks CD95L was added where indicated. Results shown are averages of three experiments performed on separate occasions. Error bars indicate 2 × SEM.
