What is Gammaglobulin (IgG)?
Gammaglobulin is an immunoglobulin (a.k.a. antibody) that is produced by B-cells, which are a type of white blood cell. B-cells produce immunoglobulins (antibodies) that kill viruses, bacteria, fungus and parasite antigens. Although the benefits of IVIG therapy are not fully understood, it is thought to inhibit damage to the myelin, thereby decreasing disease activity.
