This spring, for the first time in my life, I suffered from seasonal allergies. Not a terrible case of them, but it wasn't pleasant, and who knows what the future holds for me. Fortunately, a new study in the Journal of Biological Chemistry tells of the pinpointing of a "fossilized" molecule found in chickens that opens a new avenue of study of why humans develop severe allergic reactions. The chicken molecule, named IgY, appears to be ancestral to the IgE molecule found in humans that binds to white blood cells and causes the human immune system to overreact. This means the evolution of allergic reaction can now be traced back to at least 160 million years.
