Outcomes SAHA and VPA enhanced trastuzumab-mediated ADCP and trastuzumab-independent cytotoxicity. Mechanistically, VPA upregulated the activating antibody-binding receptor Fc-gamma receptor (FcR) IIA (Compact disc32A) on monocytes (Compact disc14+). Moreover, VPA Adrafinil and SAHA downregulated the anti-apoptotic protein myeloid leukemia cell differentiation 1 (MCL1) in breast malignancy cells. Additionally, VPA and SAHA induced an immunogenic Adrafinil cell death, characterized by the exposure of calreticulin (CALR), as well as decreased the do not eat me signal CD47 on tumor cells. Conclusions HDACi VPA and SAHA increase trastuzumab-mediated phagocytosis and trastuzumab-independent cytotoxicity. The immunomodulatory activities of those HDACi support a rationale combined treatment approach with mAb for malignancy treatment. ICD, enhances susceptibility to phagocytosis and apoptosis, as well as increases antibody-mediating receptor expression.
