Allergy and autoimmunity: Molecular diagnostics, therapy, and presumable pathogenesis

Аннотация

Allergic and autoimmune diseases represent immunopathological reactions of an organism to antigens. Despite that the allergy is a result of exaggerated immune response to foreign antigens (allergens) and autoimmune diseases are characterized by the pathological response to internal antigens (autoantigens), the underlying mechanisms of these diseases are probably common. Thus, both types of diseases represent variations in the hypersensitivity reaction. A large percentage of both the adult and pediatric population is in need of early diagnostics of these pathologies of the immune system. Considering the diversity of antibodies produced in allergic and autoimmune disease and the difficulties accompanying clinical diagnosing, molecular diagnostics of these pathological processes should be carried out in several stages, including screening and confirmatory studies. In this review, we summarize the available data on the molecular diagnostics and therapy of allergic and autoimmune diseases and discuss the basic similarities and differences in the mechanisms of their development.
