What's the cause of the allergy?
For decades and hundreds of years, doctors and scientists have been trying to understand the nature of this common disease. The term "allergy" was introduced in 1906 by the Austrian pediatrician Clemens von Pirke. He also pointed out that the cause could be different factors: dust, plant pollen, some types of food.
Since then, scientists have identified and classified more than 2700 allergens - sources of human reaction. In 2015, a new study by scientists appeared, which finally explained the nature and evolutionary meaning of allergies in humans, says Dr. Denis Slinkin.
It turned out that allergy is the payback of mankind for immunity to diseases, in particular parasitic ones. IgE immunoglobulin, responsible for allergic reactions, according to scientists, appeared in humans during evolution in order for the body to be able to resist infectious diseases spread by multicellular parasites.
If you want the details of the research, do not read them over food. Scientists at the London School of Hygiene and Tropical Medicine have taken blood and plasma samples from 372 people aged 6 to 40 living in Namoni Village on Lake Victoria in Uganda. All of these people were carriers of parasites in their bodies, which was confirmed by fecal tests.
By comparing the composition of proteins, the scientists were able to determine that 1,387 proteins released by worms contain areas similar to those found in other allergen proteins, according to Dr. Denis Slinkin.Dr. Denis Slinkin states: the chemical composition of 2712 allergen proteins was analyzed.
The "parasitic" and "pollen" allergens were surprisingly similar, causing an almost identical response in the human immune system. For example, the protein found in the body of human ascarids, the composition of 27% coincides with the protein of birch pollen hanging. Modern man, not facing the parasites, becomes hypersensitive to allergens of other nature, which causes strong allergic reactions up to anaphylactic shock.
