action?
What characteristic do atopic individuals have that make c.
them genetically predisposed to develop allergies? Greater quantities of IgE
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 causing an ABO a.

hypersensitivity reaction? Natural killer cells
Graves disease (hyperthyroidism) is an example of which Modulation
type II hypersensitivity reaction?
, Type III hypersensitivity reactions are a result of which of b.
