Summary:
Blood test results from hayfever victims testing an experimental anti-allergy drug have led investigators at the Johns Hopkins Asthma and Allergy Center to discovery of an essential immune system feedback loop that appears to be a basic mechanism driving all allergies.

Blood test results from hayfever victims testing an experimental anti-allergy drug have led investigators at the Johns Hopkins Asthma and Allergy Center to discovery of an essential immune system feedback loop that appears to be a basic mechanism driving all allergies. The biochemical loop, the scientists say, links the amount of immunoglobulin E (IgE) antibody, overabundant in people with allergies, to the number of immune cell IgE receptors, which, upon exposure to allergens, trigger a cascade of biological events that cause wheezing, sneezing, itching and swelling so common this time of year.
