Scientists May Have Discovered How to Turn Off Peanut Allergies

Great News! Researchers have found a way to turn off the immune system's reaction to peanuts - in mice. Even better news is that this research could also help unravel autoimmune diseases like multiple sclerosis and rheumatoid arthritis, since their reactions, according to scientists, are similar to those of food allergies. Researchers now need to make that leap from mice to humans, but it is a start.

A person develops food allergies after their body becomes sensitive to a particular protein from food - whatever food their body deems dangerous.  This group of researchers has found a way to wrap a tiny protein (in this case peanut protein) with a white blood cell.  Then inject it into a peanut allergic mouse.  This "tricks" the immune system into interpreting that the peanut is safe. 

“The key concept here is that we are supposed to be able to eat foods,” Bryce said. “Allergies to peanuts and other foods occur when the immune system goes wrong. We’ve been trying to understand how the immune system tells the difference between what it should and should not respond to.”
 ~ Paul J. Bryce, an assistant professor of medicine at the Northwestern University Feinberg School of Medicine, whose study was published in the Journal of Immunology.

As long as we are talking about tricks - I'm still missing any researcher comments on why food allergies have skyrocketed in the first place.  Wouldn't it be helpful to study this, as well?  To find the root cause of something with such a clear mass onset?  I'm very excited about this research, but also hope that the "why" will be discovered soon.  Tell me your thoughts.

Not a researcher, but I do have a few thoughts...probably the same ones many of us have had. Are proteins not being digested properly...and then, because of leaky gut issues stemming from antibiotic use throughout our lifetimes, entering the bloodstream? Or is it all the immunizations...could the unnatural stimulation of our immune systems be doing a little more than intended? It's definitely a delayed reaction side effect to something. Science seems to focus on immediate side effects.

Interesting thoughts, KC. Thank you.
