ANATOMY

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 act via autocrine and paracrine pathways to induce an antiviral state in infected cells and in neighboring cells containing interferon receptors. Interferons are the frontline defenders against viral infection and their primary function is to locally restrict viral propagation.

Detailed explanation-3: -Interferons (IFNs) are proteins produced by a variety of cells in the inflammatory response to infections. Their production is triggered by the immune system in response to pathogens or cytokines.

Detailed explanation-4: -Interferons are a family of structurally related, species-specific proteins that enhance the immune system released by host cells in response to the presence of pathogens such as viruses, bacteria, parasites, and tumor cells.

Detailed explanation-5: -Interferon is secreted by cells in response to stimulation by a virus or other foreign substance, but it does not directly inhibit the virus’s multiplication. Rather, it stimulates the infected cells and those nearby to produce proteins that prevent the virus from replicating within them.
