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.
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.
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.
PREVIOUS AND NEXT TERMS--------------------------------------
Ideological norm
The standard of what is normal as defined by those who, even though in a minority, exercise their authority to impose their own ideology and values on others whom they overpower.
Ideology
A set of ideas, beliefs, or principles to which a person or group adheres, lives by, and possibly dies for.
Idiopathic
Of unexplained origin, as in the development of a symptom or syndrome that is apparently spontaneously generated.
Idiosyncratic
Pertaining to one's individual and sujectively personal ideation, cognitions, affect, tastes, attitudes, habits and behaviors. As in fingerprints, irises, and DNA coding (except in identical twins) the term pertains to one's individuality in any specific measurable factor. Compare to phyletic.
Imagery
In mental life, the collective representation of mental images or depictions of anything either perceived (perceptual imagery) or, if not actually present as a sensory stimulus, recognized in memory (memory imagery), or in dream, confabulation, or fantasy (fictive imagery). Imagery refers to a predominantly visual sensory modality of input.
Immutable
Imperative

Impersonator

Impetigo
A streptococcal or staphylococcal infection that erodes the skin and dries to form a yellow-crusted sore.
Impregnation
The process of being rendered pregnant by the intromission of sperm into the uterus and the union of egg and sperm.
Imprinting
Developmental learning of a type first brought to scientific attention in studies of animal behavior by ethologists. Imprinting takes place in a given species when behavior phyletically programmed into the nervous system of that species requires a matching socioenvironmental stimulus to release it, when the matching must take place during a critical or sensitive developmental period (not before or after), and when, having occurred, the resultant behavior pattern is unusually resistant to extinction. In human beings, native language learning is a manifestation of imprinting.
