The Chemical Mediators of Anaphylaxis Are

Question

The chemical mediators of anaphylaxis are
A)found in basophils and mast cells.
B)antibodies.
C)antigens.
D)antigen-antibody complexes.
E)the proteins of the complement system.

Accepted Answer

Chemical mediators of anaphylaxis are released from mast cells and basophils in response to an allergen, leading to symptoms such as bronchoconstriction, vasodilation, and increased vascular permeability. Examples of these mediators include histamine, leukotrienes, and prostaglandins. Antibodies, antigens, and antigen-antibody complexes are involved in the immune response but are not considered primary mediators of anaphylaxis. The proteins of the complement system are also involved in the immune response but are not specific to anaphylaxis.
