BACKGROUND. SARS-COV-2 HAS A SINGLE FILAMENT RNA GENOME. AFTER ENTERING THE TARGET CELL, THE VIRUS BEGINS THE PHASES OF REPLICATION OF ITS GENOME AND SYNTHESIS OF THE NECESSARY PROTEINS. THE EPITHELIAL CELLS OF THE AIRWAY AND THE CELLS OF THE INNATE IMMUNITY (MACROPHAGES) ARE THE MAIN TARGETS OF THE VIRUS. DURING THE REPLICATION OF THE SARS-COV-2 VIRUS, DOUBLE-STRANDED RNA (DSRNA) IS GENERATED, LEADING TO THE ACTIVATION OF VARIOUS DSRNA-SENSING MECHANISMS. THE RESPONSE GENERATED INDUCES THE SYNTHESIS OF INTERFERONS, CHEMOKINES, CYTOKINES AND ON-SITE MIGRATION OF IMMUNE SYSTEM CELLS THAT AMPLIFY AND REFINE THE INITIAL RESPONSE. CORONAVIRUSES EXPRESS PROTEINS THAT ARE ABLE TO INACTIVATE DSRNA-SENSING MECHANISMS, TRIGGERING THE OVERALL DEREGULATION OF THE RESPONSE TO VIRAL INFECTION LEADING TO FURTHER DAMAGE RESULTING FROM EXCESSIVE TISSUE INFLAMMATION AND INEFFECTIVE RESPONSE OF SOME POPS
