The definition of immunoglobulin is a protein that fights against disease.
An example of an immunoglobulin is a protein that fights against strep throat.
a globulin protein that participates in the immune reaction as the antibody for a specific antigen
- Any of a group of large glycoproteins, including all the antibodies that function in the vertebrate immune system, that have a structure consisting of two heavy chains and two light chains. There are five major classes of immunoglobulin isotypes: IgA, IgD, IgE, IgG, and IgM.
- A preparation containing immunoglobulin proteins, especially immune globulin.
From immuno- + globulin.
- Patients with SCID should be treated aggressively with antibiotics for any infection, and intravenous immunoglobulin should be given to replace the antibiotics the children cannot make, but these treatments cannot cure the disorder.
- The toxin associated with tetanus, for example, is attacked by IgG1 and IgG3 antibodies; reduced percentages of either immunoglobulin subclass on a child's cells will leave the child unprotected against that specific toxin.
- Primary immunoglobulin deficiencies are primarily the result of congenital defects that affect the development and function of B lymphocytes (B cells), the white cells that fight infection and disease.
- Immunoglobulin E (IgE) is found in respiratory secretions and is directed toward invasion of the body by parasites and in allergic reactions such as hay fever, atopic dermatitis, and allergic asthma.
- Treatment with antibiotics, immunoglobulin, or blood cleansing procedures can decrease the circulating anti-strep antibodies in the blood, thus lessening the OCD symptoms in some of these children.
