proved that phagocytosis of haematopoietic tumor cells during SIRPα–CD47 blockade was strictly dependent on signaling lymphocytic activation molecule (SLAM) family receptors in vitro and in vivo (66), indicating that engagement of FcR was not needed for phagocytosis of haematopoietic tumour cells such as Raji cells. Here, SIRPA is linked to neoplasm.
