Cancer cell-expressed SLAMF7 is not required for CD47-mediated phagocytosis
Abstract
CD47 is a promising new target in cancer immunotherapy and recently the pro-phagocytic signal SLAMF7 has been shown to have a crucial role in phagocytosis induced by CD47-blocking antibody in hematological tumors. In this study, the authors demonstrate that SLAMF7 expressed by cancer cells is not required for phagocytosis suggesting that, in contrast to CD47 expression, SLAMF7 should not be used as selection criterion for CD47-targeted therapy.
