IgA plasmocytes are shown to promote resistance to the immunogenic chemotherapeutic oxaliplatin in prostate cancer mouse models by inhibiting activation of cytotoxic T cells; immunosuppressive plasma cells, which are also found in human-therapy-resistant prostate cancer, are generated in response to TGFβ, and their functionality depends on PD-L1 expression and IL-10 secretion.
