How are interferons produced
WebInterferon production could be involved in the protection conferred by the curative vaccination procedure discovered by Louis Pasteur. A paradoxical phenomenon may be observed when using high doses of infectious virus for challenge infection. Animals infected with high doses resist challenge whereas animals infected with lower doses succumb. WebThe type I interferons present in humans are IFN-α, IFN-β, IFN-ε, IFN-κ and IFN-ω. In general, type I interferons are produced when the body recognizes a virus that has invaded it. They are produced by fibroblasts and monocytes. However, the production of type I IFN-α is inhibited by another cytokine known as Interleukin-10.
