Are you allergic to any foods? Scientists have found the cure

Are you allergic to any foods? Scientists have found the cure.

According to a recent study, allergies occur when the immune system is malfunctioning

According to recent studies, allergies have increased in the last decade, becoming fatal in some cases. For example, if you are sensitive to peanuts and eat it, can cause a fatal reaction called anaphylaxis.
Scientists from several National Institutes of Health estimate that about 4.7% of children under 5 years and 3.7% who are between 5 and 17 are allergic to any type of food . In addition, each year there are between 15 000 and 30 000 cases of anaphylaxis. At present there is no reliable treatment for allergies, reports "Vitals"
A group of researchers at Northwestern University, U.S., have discovered how the immune system to set off food allergies . So far, the experiment was conducted only in mice but with great success.

Paul J. Bryce, a professor of medicine at Northwestern University Feinberg School of Medicine, said: "Allergies to peanuts and other food occur when the immune system malfunctions. We have been trying to understand how the system differentiates between what should and should not be in the body. "
However, he noted that when a person is sensitized with food, helper T cells into action as army scouts. These cells are constantly on patrol in search of the protein is considered dangerous. When they find it, call the soldiers and began a massive immune reaction that can lead to death.
Bryce and his colleagues found they could block this reaction taking some protein food, in this case peanuts, to wrap a white blood cell and then injecting these altered cells in the body of a mouse allergic.
The question is whether experimentation in mice can be applied in humans. In this regard, Bruce said there are many differences between the immune response in mice and us as well as many similarities, so the study could have great results.
The research was published in The Journal of Immunology.
