c.Hypersensitivity is best defined as a(an)
Altered immunologic response to an antigen that results in disease
A hypersensitivity reaction that produces an Anaphylaxis
allergic response is called:
The common hay fever allergy is expressed IgE
through a reaction that is mediated by which
class of immunoglobulins?
Which type of antibody is involved in type I IgE
hypersensitivity reaction?
Blood transfusion reactions are an example Alloimmunity
of:
During an IgE-mediated hypersensitivity c.
reaction, which leukocyte is activated? Eosinophils
During an IgE-mediated hypersensitivity Histamine bound to H2
reaction, the degranulation of mast cells is a
result of which receptor action?
What characteristic do atopic individuals c.
have that make them genetically Greater quantities of IgE
predisposed to develop allergies?
What is the mechanism that results in type II d.
hypersensitivity reactions? Antibodies bind to the antigens on the cell surface.
When mismatched blood is administered a.
causing an ABO incompatibility, the Complement-mediated cell lysis
erythrocytes are destroyed by
When antibodies are formed against red Phagocytosis in the spleen
blood cell antigens of the Rh system, the
blood cells are destroyed by:
When soluble antigens from infectious d.
agents enter circulation, tissue damage is a Neutrophil granules and toxic oxygen products
result of:
How are target cells destroyed in a type II d.
hypersensitivity reaction? Natural killer cells
Graves disease (hyperthyroidism) is an Modulation
example of which type II hypersensitivity
reaction?
b.
Type III hypersensitivity reactions are a result
Antibodies binding to soluble antigens that were released into body fluids and the
of which of the following?
immune complexes being deposited in the tissues
A type IV hypersensitivity reaction causes .
which result? Lymphokine-producing Th1 cells directly attacking and destroying cellular targets
, In a type III hypersensitivity reaction, the Complement activation
harmful effects after the immune complexes
that are deposited in tissues are a result of:
Raynaud phenomenon is classified as a type a.
III hypersensitivity reaction and is due to: Immune complexes that are deposited in capillary beds, blocking circulation
Deficiencies in which element can produce Zinc
depression of both B- and T-cell function?
When the maternal immune system becomes Alloimmunity
sensitized against antigens expressed by the
fetus, what reaction occurs?
Tissue damage caused by the deposition of Systemic lupus erythematosus
circulating immune complexes containing an
antibody against the host DNA is the cause
of which disease?
a.
Why does tissue damage occurs in acute
Th1 cells release cytokines that activate infiltrating macrophages, and cytotoxic T cells
rejection after organ transplantation?
directly attack the endothelial cells of the transplanted tissue.
Which blood cell carries the carbohydrate Erythrocytes
antigens for blood type?
A person with type O blood is likely to have A and B
high titers of which anti-antibodies?
Which class of immunoglobulins forms IgM
isohemagglutinins?
Which component of the immune system is T cells
deficient in individuals with infections caused
by viruses, fungi, or yeast?
In which primary immune deficiency is there DiGeorge syndrome
a partial-to-complete absence of T-cell
immunity?
How many months does it take for the 6 to 8
newborn to be sufficiently protected by
antibodies produced by its own B cells?
Considering the effects of nutritional T cells
deficiencies on the immune system, severe
deficits in calories and protein lead to
deficiencies in the formation of which
immune cells?
Urticaria are a manifestation of a which type Type I
of hypersensitivity reaction?
c.
Graves disease is a result of:
Autoantibodies binding to thyroid-stimulating hormone (TSH)-receptor sites
Raynaud phenomenon is an example of Type III
which type of hypersensitivity?
