Abstract
We conducted an experimental protocol with a nasal recombinant IFNα-2b formulation (Nasalferon) in 12 healthy volunteers who received 1 MIU per nostril twice a day, three consecutive days, and studied the induction of biomarkers related to antiviral and immune responses. Nasalferon increases the antiviral biomarker OAS1 transcript levels in oropharynx and PBMCs, regulates molecular and cellular elements related to innate and adaptive immune responses and decreases granulocytes population. These effects support Nasalferon use in virally-exposed populations.
