peptides that can bind to TCRs.
VetBooks.ir Antigen processing The series of events that degrade protein

antigens into short peptides that bind to MHC molecules so that
they can be recognized by T cells with appropriate TCRs.

Antigen-sensitive cells Cells that can bind and respond to a
specific antigen.

Antigenic determinant See Epitope.

Antigenic variation The progressive changes in surface antigens

exhibited by viruses, parasites, and some bacteria in order to
evade immune destruction.

Antigenicity The ability of a molecule to be recognized by an
antibody or lymphocyte.

Antiglobulin Antibody made against an immunoglobulin, usually
by injecting immunoglobulin into an animal of another species.

Antiglobulin test A technique for detecting the presence of
nonagglutinating antibody on the surface of a particle.

Antiserum Serum that contains specific antibodies. Synonymous
with immune globulin.

Antitoxin Antiserum directed against a toxin and used for passive
immunization.

Anurans An order of advanced amphibians that includes the frogs
and toads.

Apoptosis The controlled self-destruction of a cell; one form of
