Immunoglobulins
Immunoglobulins Antibodies or proteins found in blood and tissue fluids produced by cells of the immune system to bind to substances in the body that are recognized as foreign antigens. Immunoglobulins sometimes bind to antigens that are not necessarily a threat to health and provoke an allergic reaction.
RELATED TERMS--------------------------------------
Antibodies
Proteins produced by white blood cells. They confer immunity.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Immune
Resistant to a particular disease.
Antigens
Substances that cause an immune response in the body. The body "sees" the antigens as harmful or foreign. To fight them, the body produces antibodies, which attack and try to eliminate the antigens.
Immunoglobulins
Antibodies or proteins found in blood and tissue fluids produced by cells of the immune system to bind to substances in the body that are recognized as foreign antigens. Immunoglobulins sometimes bind to antigens that are not necessarily a threat to health and provoke an allergic reaction.
SIMILAR TERMS--------------------------------------
Immune
Resistant to a particular disease.
Immune adherence
The adherence of particulate antigen coated with C3b to tissue having cells with C3b receptors.
Immune complex
Antigen bound to antibody.
Immune modulators
Substances that control the expression of the immune response.
Immune response (Ir) gene
A gene controlling an immune response to a particular antigen; most genes of this type are in the MHC (major histocompatibility complex), and the term is rarely used to describe other types of Ir genes outside the MHC.
Immune System
The body's natural defense system which produces antibodies to fight against foreign substances such as bacteria, viruses, toxins, and cancers.
Immunity
When a body's immune system helps fend off disease.
Immunization
Natural immunity provided by antibodies or induced immunity via inoculations.
Immuno globulin E
Immuno globulin E is the antibody produced in excess in allergic patients. IgE can be measured in a blood sample to determine if a person is allergic. Allergic people usually have high levels of IgE.
Immuno-Augmentative Clinic
The Immuno-Augmentative Clinic is a hospital in Freeport, Freeport, Bahamas.
Immunoassay
Detection and assay of substances by serological (immunological) methods; in most applications the substance in question serves as antigen, both in antibody production and in measurement of antibody by the test substance.
Immunofluorescence
Technique allowing the visualisation of a specific protein in cells or tissue sections (prepared from a biopsy) by binding a specific antibody conjugated to a fluorescent substrate.
Immunogen
A substance capable of inducing an immune response (as well as reacting with the products of an immune response). Compare with antigen.
Immunoglobulin
A serum protein involved in immunity. An antibody.
Immunoglobulin (Ig)
A general term for all antibody molecules. Each Ig unit is made up of two heavy chains and two light chains and has two antigen- binding sites.
Immunoglobulin E (IgE)
A type of antibody, formed to protect the body from infection, which attaches to mast cells in the respiratory and intestinal tracts and may cause allergic rhinitis, asthma, or eczema.
Immunohistochemical staining
A laboratory process of detecting an organism in tissues with antibodies. These antibodies are labeled with a compound that is seen as a colored deposit when viewed microscopically. In general, mesotheliomas require immunohistochemical confirmation before legal measures are initiated.
Immunology
The study of the body's natural defense system.
Immunosuppresive medications
Medications that suppress the body's immune system, used to minimize rejection of transplanted organs.
Immunosuppression
The artificial suppression of the immune response, usually through drugs, so that the body will not reject a transplanted organ or tissue. Drugs commonly used to suppress the immune system after transplant include prednisone, azathioprine (Imuran), mycophenolate mofetil (CellCept), and cyclosporine (Neoral).
Immunotherapy
Stimulating the body's natural defense system to attack and destroy cancers.
Immutable
Long-lasting and unchangeable.

Statistic that equals the number of new cases of a particular disease that occur in a population during a defined period of time, usually one year.
