Here, we showed that while hexameric soluble TRAIL is able to efficiently kill the DR5 positive lymphoma Jurkat or the carcinoma HCT116, these cells are resistant to apoptosis induced by the divalent form of TRAILmim/DR5 and are poorly sensitive to apoptosis induced by an anti-DR5 agonist monoclonal antibody. This evidence concerns the gene TNFSF10 and carcinoma.
