Monoclonal Antibodies: From 1 Different Sources

An arti?cially prepared antibody (see ANTIBODIES) obtained from cell clones – a genetically identical group of cells – and comprising a single type of immunoglobulin. It neutralises only one speci?c ANTIGEN. The antibodies are prepared by linking antibody-forming lymphocytes (see LYMPHOCYTE) from the spleen of mice with myeloma cells from mice. Monoclonal antibodies are used in the development of new vaccines and in the study of human cells, hormones, and micro-organisms. Research is under way for their use in the treatment of some forms of cancer. (See IMMUNOLOGY.)

Monoclonal Antibody

See antibody, monoclonal.... monoclonal antibody

Antibodies

Antibodies are substances in the blood which destroy or neutralise various toxins or ‘bodies’

(e.g. bacteria), known generally as antigens (see ANTIGEN). The antibodies are formed, usually, as a result of the introduction into the body of the antigens to which they are antagonistic, as in all infectious diseases (see ALLERGY; IMMUNITY).... antibodies

Antibody, Monoclonal

An artificially produced antibody that neutralizes only one specific antigen (foreign protein).

Monoclonal antibodies are produced in a laboratory by stimulating the growth of a large number of antibody-producing cells that are genetically identical. In effect, this process enables antibodies to be tailor-made so that they will react with a particular antigen.

Monoclonal antibodies are used in the study of human cells, hormones, microorganisms, and in the development of vaccines. They are also being used in the diagnosis and treatment of some forms of cancer.... antibody, monoclonal

Anticardiolipin Antibodies

autoantibodies that are directed against phospholipid-binding plasma proteins found in *antiphospholipid antibody syndrome, which is characterized by venous and arterial thrombosis and recurrent miscarriages.... anticardiolipin antibodies

Gad Antibodies

see islet cell antibodies.... gad antibodies

Islet Cell Antibodies

a group of autoantibodies directed against components of the insulin-secreting beta cells of the pancreas. They are usually detectable in the blood of people presenting with type 1 diabetes. Antibodies against *glutamic acid decarboxylase (GAD) in the beta cells have become a more specific test for islet cell antibodies, to help confirm a diagnosis of type 1 diabetes.... islet cell antibodies

Thyroid Antibodies

autoantibodies directed against the cells of the thyroid gland, which serve as a marker of autoimmune thyroid disease. There are two main types: antibodies directed against the thyroid peroxidise (TPO) enzyme; and anti-thyroglobulin, directed against the thyroid colloid (see thyroid gland). The highest level of thyroid antibodies is found in *Hashimoto’s disease.... thyroid antibodies

Tsh Receptor Antibodies

autoantibodies targeted against the *thyroid-stimulating hormone (TSH) receptor of the thyroid cells. They can activate the TSH receptor, leading to the hyperthyroidism of *Graves’ disease, or they can block the TSH receptor, causing *hypothyroidism.... tsh receptor antibodies
