Preventing the Appearance of the Symptoms of an Allergy Attack

Question

Preventing the appearance of the symptoms of an allergy attack would be the likely result of
A) blocking the attachment of the IgE antibodies to the mast cells.
B) blocking the antigenic determinants of the IgM antibodies.
C) reducing the number of helper T cells in the body.
D) reducing the number of cytotoxic cells.
E) reducing the number of natural killer cells.

Accepted Answer

IgE antibodies are responsible for triggering mast cells to release histamine, which causes allergy symptoms. Blocking the attachment of IgE to mast cells would prevent this release of histamine, thus preventing allergy symptoms from appearing. The other choices are not related to allergy attacks.
