Modeling of viral–bacterial coinfections at the molecular level using agonists of innate immunity receptors

Аннотация

The combined effect of innate immunity receptors in viral–bacterial coinfections was studied in vitro using the primary culture of murine macrophages activated by different combinations of ligands of innate immunity receptors belonging to the family of Toll-like receptors. The activation of macrophages first with a viral ligand and then with a bacterial one significantly decreased the expression of proinflammatory cytokine genes. Such attenuation of immune responses may occur during the development of bacterial complications in viral infections.
