reaction, which leukocyte is activated? Eosinophils

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?

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

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

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.

immunity?

newborn to be sufficiently protected by
antibodies produced by its own B cells?

of hypersensitivity reaction?
c.

Raynaud phenomenon is an example of Type III
which type of hypersensitivity?
