Abstract:
The fairly widespread prevalence of CRSwNP along with the lack of remedies for curing the
disease, a variety of hypotheses of etiology dictate the need for further study of all links in the
pathogenesis and clinical features of the course of the disease. In the coming century of “biological
medicine”, the availability of high technologies of medical genetics makes it possible to reveal
the individual characteristics of the most important regulatory systems of the body, which opens
up new prospects for studying the etiology and pathogenesis of CRSwNP. In the tissues of polyps
and intranasal secretions, an increase in the concentration of various infl ammatory mediators, in
particular interleukins, is observed due to an increase in their de novo synthesis by effector cells.
Particular importance is attached to an increase in the concentration of cytokines involved in the
development, recruitment and activation of eosinophils (IL-4, IL-12, IL-13, GM-CSF), the main pro infl ammatory (IL-1, IL-2, TNF-a, IL- 10), regulatory cytokines (IL-10, TLR2B), contributing to the
chronicity of the infl ammatory process in the nasal cavity
