About two billion people have allergic complications, according to estimates of the American Academy of Allergy and Immunology. Not any other illness, at any moment of history, affected as much people. Specialists start to face it as an epidemic. Only in the United States, each year 5 000 people die suffocated during asthma crises, and 90 million Americans deal daily with the discomfort of rhinitis and dermatitis, the more common allergic varieties. Finding the cure or the causes for this became, thus, a challenge that involves more than interests of public health.
