Much research has been done on the origins of allergies, as well as on which might reduce their severity. While some scientists investigate what triggers allergic reactions in the body, others are looking into the mechanisms by which they occur. Recently, a group of Swedish immunologists found that a common anticoagulant molecule plays a big part in many allergic reactions.
The compound is called heparin, and it both naturally occurs in the body and is synthesizeable in the laboratory. Researchers at the Karolinska Institutet have determined that heparin facilitates the inflammation that occurs in an allergic reaction.
During such a reaction, the body produces heparin, which activates a specific kind of immune body called a mast cell, the team said. These cells in turn make bradykinin, a protein that leads to inflammation, porousness of the blood vessels and even anaphylactic shock.
Scientists are not yet sure how to slow or stop this response. Until they are, it may be advisable to take an herbal; supplement or vitamin tablet, in order to maintain maximum bodily health.
