INTRODUCTION Flashcards
defined as the resistance to disease, specifically infectious disease
Immunology
defined as the study of a host’s reaction when foreign substances are introduced into the body
Immunology
diagnostic examination of blood serum and other bodily fluids with regards to the response of the immune system to pathogens
serology
phenomenon in which exposure to one infectious agent produces protection against another agent
cross immunity
where did small pox originate from?
cow pox
substance that stimulates antibody formation and has the ability to bind to an antibody
Antigens
Any substance that is capable of inducing an immune response.
Immunogen
a low-molecular-weight, nonantigenic substance that, when combined with an
antigen, changes the antigenic specificity of that antigen.
Hapten
glycoprotein substance (immunoglobulin) that is produced by B lymphocytes
in response to an antigen.
Antibody
derived from a single B-cell clone and are produced as a
single class of immunoglobulin with specificity unique to the antigenic stimulus.
Monoclonal antibody
produced as different classes of immunoglobulins by many Bcell clones in response to an antigen
polyclonal antibodies
Antibodies produced in response to antigens from another species
heteroantibodies
other name for heteroantibodies
xenoantibodies
formed in response to antigens from individuals of the same species
alloantibodies
produced by the body’s immune system against “self” antigens
Autoantibodies
part of an antigen that reacts specifically with an antibody or T-cell receptor
epitope
the clumping of particulate antigens by antibodies specific for the
antigens
agglutination
is the tendency that an epitope has for combining with the antigen-binding site on an antibody molecule
affinity
strength of the bond between the antigen and the antibody.
avidity
smallest amount of antigen or antibody that can be detected
sensitivity
ability of an antibody to bind to an antigen with complementary
determinants and not to an antigen with dissimilar determinants.
specificity
group of proteins synthesized in mononuclear phagocytes, hepatocytes, fibroblasts, and some endothelial cells.
complement
A small peptide formed during complement activation that causes
increased vascular permeability, contraction of smooth muscle, and release of histamine from basophils and mast cells.
anaphylatoxins
A life-threatening response to an allergen characterized by the systemic release of histamine
Anaphylaxis
father of immunology
