These intravenous immunoglobulins (IVIg) represent the healthy human IgG repertoire, which can be reactive for both self and non-self antigens. A better characterization of IVIg’s repertoire is an important aspect to enable its effective utilization as an immunomodulatory treatment. In this study we have investigated the reactivity of IgG1, IgG2, IgG3 and IgG4 present in IVIg for a small selection of antigens, including actin, DNA, ferritin and thyroglobulin. We observed that two commercial preparations of therapeutic immunoglobulins contain very high reactivity for thyroglobulin, which was predominantly detected by IgG4. Since IgG4 antibodies can have immunomodulatory properties, these result suggest that these anti-thyroglobulin may have a role in the IVIg treatment of autoimmune disease characterized by high avidity for anti-thyroglobulin antibodies such as Hashimoto’s disease.展开更多
