Elevated levels of circulating immune complexes are associated with autoimmunity and with worse prognoses in cancer. Here, we examined the effects of well-defined, soluble immune complexes (ICs) on human peripheral T cells. We demonstrate that IgG-IC

SummaryAll clinically approved antibodies are of the IgG isotype and mediate the clearance of target cells via binding to Fcγ receptors and complement (C1q). Even though IgA can elicit powerful cytotoxic action via FcαRI receptor binding, IgA antib
