Chapter 20.7, Problem 22CYU
Summary Introduction
To review:
Events triggering the release of histamine from mast cells in an allergic response.
Introduction:
Hypersensitivities are caused when the immune system of the body causes damage to body’s own tissue when it fights or resists a threat. This threat may be an allergen that can induce an immune response. There are different types of hypersensitivities based on different parameters. The hypersensitivities that involve antibody reactions are of two types namely, the immediate and subacute hypersensitivities.
