Role of proteins MRP8 (S100A8) and MRP14 (S100A9) in the development of critical condition in patients with pneumonia with A/H1N1 influenza

Background. Today, the critical care medicine is actively developing, and rapid progress is closely related to the achievements of molecular biology, immunology, and pathological physiology. The study of the role of individual molecular structures in the realization of the reactions of innate and ad...
