CD47 and lymphoma: Previous reports have shown that CD47 blockade induces efferocytosis of lymphoma cells via Fc-FcR interactions (29, 30), and efferocytosis assay of ANCA-induced NETs using FcR blocker or anti-CD47 F(ab’)2 in this study showed that the effects of anti-CD47 mAb on efferocytosis were FcR dependent.
