PREPARATION
,What do the initials E.L.I.S.A. stand for?
Enzyme Linked Immunosorbent Assay
What is an antigen?
Foreign material that triggers an immune response.
What is an antibody?
An immunoglobulin created in response to an antigen introduced into an animal's body.
What is antiserum?
Serum removed from an animal that contains antibodies against a specific antigen.
What is agglutination?
A clumping reaction of substances, seen in blood and other chemical reactions.
What is natural immunity?
Immunity an animal is born with.
What is acquired immunity?
Immunity that an animal makes itself (active) or receives (passive) after birth.
What are immunoglobulins?
Proteins created by the immune system in response to a specific antigen.
What is serology?
The study of serum for the presence of antigens or antibodies.
What is a titer?
A measurement of the quantity of an antibody present in a patient's blood.
What is a T-cell?
A type of lymphocyte differentiated in the thymus, associated with cell-mediated
immunity.
What is a B-cell?
A lymphocyte differentiated in the bursa equivalent or bone marrow, associated with
humoral immunity.
Which white blood cells are responsible for most antibody production?
B-lymphocytes.
What is the name of the cell that B-lymphocytes turn into when actively
producing antibodies?
Plasma cell or Plasmacyte.
What is an antigen test in E.L.I.S.A.?
Tests for a specific antigen present in the blood at the time of testing.
What is an antibody test in E.L.I.S.A.?
Shows that the animal has been exposed to the antigen at some point.
What is a competitive test in E.L.I.S.A.?
Determines the quantity of a substance in the blood, usually hormones or drugs.
What is IgM?
The antibody formed when an animal is first exposed to an antigen.
What is IgG?
The antibody formed at the second exposure to the same antigen.
What is IgA?
Antibodies found in bodily secretions, generalized to attack many different antigens.
What is IgE?
A type of antibody associated with allergic reactions.
What are the main differences between humoral and cell-mediated immunity?
,Humoral immunity involves B-lymphocytes creating antibodies, while cell-mediated
immunity involves T-lymphocytes physically attacking antigens.
Immunology -ANSWER✅✅✅Study of a host's reactions when foreign substances are
introduced into the body
Antigens -ANSWER✅✅✅Foreign substances that induce a host response
Immunity -ANSWER✅✅✅The condition of being resistant to infection
Edward Jenner -ANSWER✅✅✅Successfully prevented infection with smallpox by
injecting a more harmless substance- cowpox from a disease affecting cows
Louis Pasteur -ANSWER✅✅✅Father of immunology- observed by chance that older
bacterial cultures would not cause diseases in chickens (first attenuated vaccine)
Used attenuation to prevent rabies in affected individuals
Attenuation -ANSWER✅✅✅Change- make a pathogen less virulent (heat, aging, or
chemical means)
Phagocytes -ANSWER✅✅✅Cells that eat- part of natural or innate host defense
humoral immunity -ANSWER✅✅✅specific immunity produced by B cells (plasma cells)
that produce antibodies that circulate in body fluids
Antibodies -ANSWER✅✅✅Serum proteins produced by certain lymphocytes when
exposed to a foreign substance and they react specifically with that foreign substance
Innate (natural) immunity -ANSWER✅✅✅The individual's ability to resist infection by
means of normally present body functions
Adaptive immunity -ANSWER✅✅✅Type of resistance that is characterized by
specificity for each individual pathogen, or microbial agent, and the ability to remember
a prior exposure
increased response to that pathogen upon repeated exposure
Leukocytes -ANSWER✅✅✅White blood cells in the peripheral blood that play a key
role in both innate and adaptive immunity
5 principal types of leukocytes in peripheral blood -ANSWER✅✅✅Neutrophils,
eosinophils, basophils, monocytes, lymphocytes
Innate immune cells in periphery -ANSWER✅✅✅Neutrophils, eosinophils, basophils,
monocytes
, Adaptive immune cells in periphery -ANSWER✅✅✅Lymphocytes
Tissue cell lines -ANSWER✅✅✅Mast cells, macrophages, and dendritic cells
All blood cells arise from a type of cell -ANSWER✅✅✅Hematopoietic stem cell (HSC)
HSC gives rise to two distinct types of precursor cells: -ANSWER✅✅✅Common
myeloid precursors (CMP) and Common lymphoid precursors (CLP)
The common myeloid precursor gives rise to: -ANSWER✅✅✅Phagocytic cells:
Monocytes/Macrophages, Neutrophils, Eosinophils, Basophils, Erythrocytes, Platelets
The common lymphoid precursor gives rise to: -ANSWER✅✅✅T/NK progenitors (T
and NK cells) and B cell progenitors (B cell and dendritic cells)
Neutrophils -ANSWER✅✅✅Polymorphonuclear neutrophilic leukocyte
50-75% of total peripheral WBCs in adults
Azurophilic or primary granules -ANSWER✅✅✅Contains antimicrobial products such
as myeloperoxidase, lysozyme, elastase, proteinase-3, cathepsin G, and defensins
secondary granules -ANSWER✅✅✅Lysozyme, lactoferrin, collagenase, gelatinase,
and respiratory burst components
Diapedesis -ANSWER✅✅✅Passage of white blood cells through intact vessel walls
into tissue
Chemotaxins -ANSWER✅✅✅chemical messengers that cause cells to migrate in a
particular direction
Eosinophils -ANSWER✅✅✅1-3% of the circulating WBCs in a nonallergic person
Eosinophil granules -ANSWER✅✅✅Catalase, lysozyme, cytokines (chemical
messengers), growth factors, and cationic proteins
Role of eosinophils -ANSWER✅✅✅Attack parasites and toxic proteins and allergic
responses. Regulation of mast cell function
Basophil -ANSWER✅✅✅<1% in peripheral blood
Short lifespan
Basophil granules -ANSWER✅✅✅histamine, cytokines, growth factors, and heparin
Function of histamine -ANSWER✅✅✅Contracts smooth muscle
