    Human cytomegalovirus antagonizes activation of Fcγ receptors by distinct and synergizing modes of IgG manipulation

    Philipp Kolb et al.
    Molecular mechanisms reveal that human cytomegalovirus has evolved to deploy two individual glycoproteins working in synergy to efficiently evade antibody-mediated immunity mediated by Fc-gamma receptors.

    Soluble Fas ligand drives autoantibody-induced arthritis by binding to DR5/TRAIL-R2

    Dongjin Jeong et al.
    Soluble Fas ligand interacts specifically with tumor necrosis factor receptor superfamily (TNFRSF)10B, also known as death receptor 5, exacerbating arthritis in a Fas-independent manner.
