primary follicles

Biology; Immunology

Lymphoid tissues contain lymphoid follicles made up of follicular dendritic cells and B lymphocytes. The primary follicles contain resting B lymphocytes and are the site at which ...

graft-versus-host

Biology; Immunology

When mature T lymphocytes are injected into a nonidentical immunoincompetent recipient, they can attack the recipient, causing a graft-versus-host (GVH) reaction; in human ...

enzyme-linked immunosorbent assay

Biology; Immunology

The enzyme-linked immunosorbent assay (ELISA) is a serological assay in which bound antigen or antibody is detected by a linked enzyme that converts a colorless substrate into a ...

immune surveillance

Biology; Immunology

It has been proposed that most tumors that arise are detected and eliminated by immune surveillance mediated by lymphocytes specific for tumor antigens. There is little evidence ...

antibody-dependent cell-mediated cytotoxicity

Biology; Immunology

Antibody-dependent cell-mediated cytotoxicity (ADCC) is the killing of antibody-coated target cells by cells with Fc receptors that recognize the constant region of the bound ...

immunogenetics

Biology; Immunology

Immunogenetics was originally the analysis of genetic traits by means of antibodies against genetically polymorphic molecules such as blood group antigens or MHC proteins. ...

continuous epitopes

Biology; Immunology

Continuous epitopes, or linear epitopes, are antigenic determinants on proteins that are contiguous in the amino acid sequence and therefore do not require the protein to be ...
