Sorry, no etymologies found.
But this is not a true allergy, like the hives or anaphylaxis that can come from a peanut allergy that is called an IgE allergy.
The process, in which an antibody, called an IgE antibody, that is supposed to fight infections like parasites, instead recognizes certain food proteins as abnormal invaders within the body.
In people with a genetic predisposition for allergies, "certain proteins from pollens, called allergens, can induce the immune system to produce a specific type of antibody called IgE antibody," says Fauci.
Allergies result when a particular form of antibody called IgE binds to special "allergy" cells known as mast cells.
This immune response elevates the level of a blood antibody known as IgE.
The surface antibodies associated with allergies called IgE antibodies stick to B cells like green on peas, supercharging them to fight invaders that may not be particularly dangerous.
So, what happened in this study is that Harvard researchers looked at more than 300 pregnant women, and they measured stress levels, they gave them questionnaires and then they looked at levels of something called IgE in the baby's umbilical cords after they were born.
Aimed at treating moderate to severe asthma triggered by allergies, Xolair works by disabling a naturally occurring antibody called IgE that triggers the release of chemicals that cause inflammation.
Those using the device also had significantly smaller increases in another indicator of persistent and more severe inflammation - a chemical known as IgE immunoglobulin E.
"The point about allergies is that you respond with a class of antibodies called IgE whose function remains unknown," said Marshall Plaut, chief of the allergic mechanisms section at the National Institutes of Allergy and Infectious Diseases.
