Antibody Diversity - 새창 The phenomenon of immense variability characteristic of ANTIBODIES. It enables the IMMUNE SYSTEM to react specifically against the essentially unlimited kinds of ANTIGENS it encounters. Antibody diversity is accounted for by three main theories: (1) the Germ Line Theory, which holds that each antibody-producing cell has genes coding for all possible antibody specificities, but expresses only the one stimulated by antigen; (2) the Somatic Mutation Theory, which holds that antibody-producing cells contain only a few genes, which produce antibody diversity by mutation; and (3) the Gene Rearrangement Theory, which holds that antibody diversity is generated by the rearrangement of IMMUNOGLOBULIN VARIABLE REGION gene segments during the differentiation of the ANTIBODY-PRODUCING CELLS.
Synonyms : Antibody Diversities, Diversities, Antibody, Diversity, Antibody, Germ Line Theories, Theories, Germ Line, Theory, Germ Line
Antibody Formation - 새창 The proliferation and differentiation of B-LYMPHOCYTES into PLASMA CELLS or memory cells. On stimulation by ANTIGENS, those cells then produce ANTIBODIES.
Synonyms : Antibody Responses, Formation, Antibody, Humoral Immunities, Humoral Immunity, Immunities, Humoral, Production, Antibody, Response, Antibody, Responses, Antibody
Antibody Specificity - 새창 The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.
Synonyms : Antibody Specificities, Specificities, Antibody, Specificity, Antibody
Antibody-Coated Bacteria Test, Urinary - 새창 Fluorescent antibody technique for visualizing antibody-bacteria complexes in urine. The presence or absence of antibody-coated bacteria in urine correlates with localization of urinary tract infection in the kidney or bladder, respectively.
Synonyms : Antibody Coated Bacteria Test, Urinary, Urinary Antibody-Coated Bacteria Test, Urinary Antibody Coated Bacteria Test
Antibody-Dependent Cell Cytotoxicity - 새창 The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
Synonyms : Cell Cytoxicity, Antibody-Dependent, Antibody Dependent Cell Cytotoxicity, Antibody-Dependent Cell Cytotoxicities, Antibody-Dependent Cell Cytoxicities, Antibody-Dependent Cell Cytoxicity, Cell Cytotoxicities, Antibody-Dependent
