Explanation:
Detailed explanation-1: -Interferons (IFNs)-the body’s first line of antiviral defence-are cytokines that are secreted by host cells in response to virus infection. By inducing the expression of hundreds of IFN-stimulated genes, several of which have antiviral functions, IFNs block virus replication at many levels.
Detailed explanation-2: -Interferons provide a first line of defence against virus infections by generating an intracellular environment that restricts virus replication and signals the presence of a viral pathogen to the adaptive arm of the immune response.
