A tick bite can have unforeseen consequences that Some people suffer after a sudden meat Allergy. Scientists from the University of Virginia School of Medicine have investigated the immunological characteristics of people with a meat Allergy and find one.
People who develop an allergic reaction to the meat of mammals such as beef, lamb or pork, have large amounts of a particular Form of immune cells in the blood, the cells are B known. By the bite of the tick, these white blood cells antibodies to produce so-called IgE antibodies. This IgE reacts to the consumption of meat to a specific sugar that is found therein, and to release substances that trigger the allergic symptoms.
The Team of Dr. Loren Erickson of the Department of Microbiology, immunology and cancer biology at the University of Virginia has developed an experimental model in mice. To help to a better understanding of how proteins of the tick to trigger the immune response in humans, which leads to the production of antibodies against flesh. "This is the first clinically relevant model that is known to me. We can use this model to find the meat Allergy underlying causes. So that we can identify possible mechanisms that could lead to new therapeutic strategies."
People who develop after the bite, the American Lone Star tick (Amblyomma americanum), an Allergy, often have to dispense with the consumption of mammalian meat and carefully make sure no food with "verstecktem" To eat meat. The symptoms of meat Allergy can range from mild hives of Nausea and vomiting to life-threatening anaphylactic shock. The Allergy was discovered in 2011 by Thomas Platts-Mills, a renowned allergist at the University of Virginia, found that the sugar alpha-galactose is in the meat of mammals of the shutter button.
