Immunology

Immunology is the study of the structuree and function of the immune system which is responsible for the protection from invading foreign macromolecules or organisms. It is a broad branch of biomedical science that covers the study of all aspects of the immune system in organisms. It deals with the physiological functioning of the immune system in both healthy states and immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency, transplant rejection); the physical, chemical and physiological characteristics of the components of the immune system in vitro, in situ, and in vivo.

Immunology

Immunoglobulin (Ig)

Biology; Immunology

A general term for all antibody molecules: IgM, IgD, IgG, IgA, IgE; each Ig unit is made up of two heavy chains and two light chains and has two antigen-binding sites.

Immune adherence

Biology; Immunology

The adherence of particulate antigen coated with C3b to cells expressing C3b receptors; results in enhanced phagocytosis of bacteria by macrophages.

Immediate-type hypersensitivity

Biology; Immunology

Type I hypersensitivity reaction occurring within minutes after the interaction of antigen and IgE antibody.

Immunoglobulin superfamily

Biology; Immunology

Proteins involved in cellular recognition and interaction that are structurally and genetically related to immunoglobulins.

Immunodeficiency

Biology; Immunology

Decrease in immune response that results from absence or defect of some component of the immune system.

Immunodiffusion

Biology; Immunology

Identifies antigen or antibody by the formation of antigen-antibody complexes in a gel.

Immune modulators

Biology; Immunology

Substances that control the level of the immune response.
