clonal expansion

Biology; Immunology

Clonal expansion is the proliferation of antigen-specific lymphocytes in response to antigenic stimulation and precedes their differentiation into effector cells. It is an ...

anaphylactic shock

Biology; Immunology

Anaphylactic shock or systemic anaphylaxis is an allergic reaction to systemically administered antigen that causes circulatory collapse and suffocation due to tracheal swelling. ...

anaphylatoxins

Biology; Immunology

Anaphylatoxins are small fragments of complement proteins, released by cleavage during complement activation. These small fragments are recognized by specific receptors, and they ...

phage display library

Biology; Immunology

Antibody-like phage can be produced by cloning immunoglobulin V-region genes in filamentous phage, which thus express antigen-binding domains on their surfaces, forming a phage ...

early induced responses

Biology; Immunology

The early induced responses or early nonadaptive responses are a series of host defense responses that are triggered by infectious agents early in infection. They are distinct ...

B7 molecules

Biology; Immunology

The major T-cell co-stimulatory molecules are the B7 molecules , B7.1 (CD80) and B7.2 (CD86). They are closely related members of the immunoglobulin gene superfamily and both bind ...

N-nucleotides

Biology; Immunology

N-nucleotides are inserted into the junctions between gene segments of T-cell receptor and immunoglobulin heavy-chain V-region genes during gene segment joining. These N-regions ...
