Immunoglobulin E and Allergy

This article will explain how the antibody immunoglobulin E, or IgE, affects the development of allergies.

IgE in the Body

Allergy is referred to as a hypersensitivity to some substance, usually a protein found in animal dander or food for example. IgE is a substance in the body that helps the body to recognize foreign invaders to the body, like parasites, and help the body to fight against them. It is an immune system reaction in the body that is intended to safeguard the body against threats to the immune system. Therefore, allergy is a condition where IgE recognizes the allergen and is involved with the allergy symptom development in the body. People with allergies have higher levels of IgE in their bloodstream than people with no allergy because the more there is IgE, the more severe the allergic reaction will be.

Histamines and IgE

When IgE interacts with an allergic trigger like the protein that are in dust mites when they are breathed in. This creates histamines in the body. Histamines are involved with the allergic symptoms that come about when allergy is triggered. Therefore, an allergy symptom like rash or runny nose can develop when histamines are released because of IgE response to an allergen in the body.

Latest News About IgE

New research in treatments for allergies intends to find out if the reaction between the allergen and IgE can be interfered with, so that an allergic response in the body could be prevented. This would mean that typical allergy medications, like antihistamines, would not have to be prescribed. This would be a benefit because these often have side effects because they do not target the symptoms directly, but instead, they are involved with a very broad range of influence on the body. This makes their use complicated when it comes to allergy treatment.
