Fig. 3. Assembly of the CD95 DISC is independent of CD95 capping. (A) Jurkat and H9 cells were assessed for the presence of caspase-8 in the CD95 DISC by immunoprecipitation of CD95 after stimulation with
CD95 for the indicated time. (B) Jurkat and H9 cells were pretreated as in Fig. 2A and were then subjected to immunoprecipitation of CD95 after stimulation with
CD95 for 10 minutes. Cell lysates and IP samples were analyzed for the presence of caspase-8. The treatments that abolished CD95 capping did not inhibit recruitment of caspase-8 and assembly of the CD95 DISC. Representative immunoblots from two separate experiments are shown.
