    ..These results suggest that combining ibrutinib with monoclonal antibody therapy could enhance chronic lymphocytic leukemia cell killing without affecting macrophage effector function. ..

    ..These data suggest that activation of TLR4 on monocytes can induce a rapid down-regulation of FcγRIIb protein and that this involves ubiquitination. ..

    ..These results suggest that IFN? can re-educate NLCs and shift them toward an effector-like state and that therapies promoting local IFN? production may be effective adjuvants for antibody therapy in CLL. ..

    ..Taken together, these studies show a novel mechanism of daratumumab-mediated killing and a possible new therapeutic strategy for AML. ..
