Abstract

The effect of the IgE-mediated reaction on the passive cutaneous anaphylaxis (PCA) reaction was studied at local skin sites of monkeys, and we found that the IgE-mediated reaction appeared to enhance the PCA reaction. Interactions among IgE-mediated reaction, PCA reaction and delayed hypersensitivity reaction were also determined. Contact dermatitis induced with DNCB was utilized as the delayed hypersensitivity reaction. The IgE-mediated reactior or PCA reaction, as well as simple serum irritation, enhanced the delayed hypersensitivity reaction. It is thus assumed that the IgE-mediated reaction enhances the PCA reaction and that this in turn accelerates the delayed hypersensitivity reaction.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
