  Ia-Like Antigens, Human



Ia-Like Antigens, Human

   Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.

RELATED TERMS
--------------------------------------

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.

B-lymphocytes
Or B-cells are white blood cells that produce and secrete antibodies into the blood. See also Cell memory.

Genes
Basic, functional units of heredity, each occupying a specific place on a chromosome.

HLA-D
Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.

Families
A social group consisting of parents or parent substitutes and children.

Glycopeptides
Proteins which contain carbohydrate groups attached covalently to the polypeptide chain. The protein moiety is the predominant group with the carbohydrate making up only a small percentage of the total weight.

HLA-DR
A group of D-related human leukocyte antigens that are polymorphic glycoproteins found on lymphoid cells. They consist of alpha and beta chains and their inheritance differs from that of the DQ and DP antigens; their presence seems to be associated with certain skin diseases like pemphigus vulgaris, dermatitis herpetiformis, and type I diabetes.

Glycoproteins
Conjugated protein-carbohydrate compounds including mucins, mucoid, and amyloid glycoproteins.

Diseases
A definite pathologic process with a characteristic set of signs and symptoms. It may affect the whole body or any of its parts, and its etiology, pathology, and prognosis may be known or unknown.

Immune
Resistant to a particular disease.

Etiology
The theory of the factors in the genesis, origin, or cause of a disorder or disease.



SIMILAR TERMS
--------------------------------------

Ia-Like Antigens
Large, transmembrane, non-covalently linked glycoproteins (alpha and beta). Both chains can be polymorphic although there is more structural variation in the beta chains. The class II antigens in humans are called HLA-D ANTIGENS and are coded by a gene on chromosome 6. In mice, two genes named IA and IE on chromosome 17 code for the H-2 antigens. The antigens are found on B-lymphocytes, macrophages, epidermal cells, and sperm and are thought to mediate the competence of and cellular cooperation in the immune response. The term IA antigens used to refer only to the proteins encoded by the IA genes in the mouse, but is now used as a generic term for any class II histocompatibility antigen.

Ivinson Memorial Hospital
The Ivinson Memorial Hospital is a hospital in Laramie, Wyoming, United States.

The Inverell District Hospital is a hospital in Inverell, New South Wales, Australia.

IA1, Cytochrome P450
A cytochrome P-450 enzyme capable of activating procarcinogenic polycyclic hydrocarbons and halogenated aromatic hydrocarbons into mutagenic compounds. Ethoxyresorufin acts as a substrate for CYP1A1 and measurement of ethoxyresorufin O-deethylase provides a more direct method of detection for this enzyme. EC 1.-.

IAIMS
A concept, developed in 1983 under the aegis of and supported by the National Library of Medicine under the name of Integrated Academic Information Management Systems, to provide professionals in academic health sciences centers and health sciences institutions with convenient access to an integrated and comprehensive network of knowledge. It addresses a wide cross-section of users from administrators and faculty to students and clinicians and has applications to planning, clinical and managerial decision-making, teaching, and research. It provides access to various types of clinical, management, educational, etc., databases, as well as to research and bibliographic databases. In August 1992 the name was changed from Integrated Academic Information Management Systems to Integrated Advanced Information Management Systems to reflect use beyond the academic milieu.
