WebJan 10, 2024 · Neuraminidase inhibitors (NAIs) are a class of drugs which block the neuraminidase enzyme. They are commonly used as antiviral drugs because they block … WebPathogenicity is determined by the interaction of viral proteins with each other or with host factors. This concept is supported by many studies on the viral envelope proteins. Proteolytic activation of the hemagglutinin as a fusion protein has been known for a long time to be an important determinant of pathogenicity.
