Allergic reactivity - evolutionary attainments by highly organized animals

The paper has given an insight of allergy as evolutionary selected reactivity for highly organized animals. This reactivity is directed to organization of allergen-specific inflammation and serves as biologically expedient, high-specific and high-sensitive reaction in response to allergen entering into the organism because of barrier tissue dysfunction (higher allergen permeability). such insight has raised a question on consequences of allergy reactivity elimination for highly organized animals and their posterity.
