INNATE IMMUNE STATUS IN ADVANCED DISEASES OF THE UPPER RESPIRATORY TRACT AGAINST THE BACKGROUND OF COVID-19 INFECTION

Abstract

Innate immunity is the first line of defense of the host and plays a key role in reducing the spread of pathogens. Unlike adaptive immunity, which works by creating special receptors against microbial antigens (for example, antibodies or TCR), innate immunity is based on the recognition of common molecular structures present in microbial structures.
