    ..Hence we have identified granzyme B as an important mediator of FcγR function in human monocytes and have uncovered another mechanism by which TLR8 agonists may enhance FcγR-based therapies. ..

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

    ..These findings both provide a molecular mechanism for SHIP association with native ITAM-bearing receptors and demonstrate that SHIP association with ITAM-FcgammaR serves to regulate gene expression during the phagocytic process. ..

    ..These data provide insight into the regulation of immune responses by TGF-beta1 and demonstrate the selectivity of these effects. ..

    ..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. ..
