immunoglobulin
- n a class of proteins produced in lymph tissue in vertebrates and that function as antibodies in the immune response
immunoglobulin a
- n one of the most common of the five major classes of immunoglobulins; the chief antibody in the membranes of the gastrointestinal and respiratory tracts
immunoglobulin d
- n one of the five major classes of immunoglobulins; present in blood serum in small amounts
immunoglobulin e
- n one of the five major classes of immunoglobulins; present primarily in the skin and mucous membranes
immunoglobulin g
- n one of the five major classes of immunoglobulins; the main antibody defense against bacteria
immunoglobulin m
- n one of the five major classes of immunoglobulins; involved in fighting blood infections and in triggering production of immunoglobulin G
immunohistochemistry
- n an assay that shows specific antigens in tissues by the use of markers that are either fluorescent dyes or enzymes (such as horseradish peroxidase)
immunologic response
- n a bodily defense reaction that recognizes an invading substance (an antigen: such as a virus or fungus or bacteria or transplanted organ) and produces antibodies specific against that antigen
immunology
- n the branch of medical science that studies the body's immune system
immunopathology
- n the branch of immunology that deals with pathologies of the immune system
immunosuppressant
- n a drug that lowers the body's normal immune response
immunosuppression
- n lowering the body's normal immune response to invasion by foreign substances; can be deliberate (as in lowering the immune response to prevent rejection of a transplanted organ) or incidental (as a side effect of radiotherapy or chemotherapy for cancer)
immunosuppressive drug
- n a drug that lowers the body's normal immune response
immunosuppressor
- n a drug that lowers the body's normal immune response
