Interferons (IFN s, / ˌɪntərˈfɪərɒn / IN-tər-FEER-on[1]) are a group of signaling proteins [2] made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.

Interferons are the frontline defenders in your body. A variety of cells, including white blood cells, produce interferons in response to infection and other stimuli, like cancer cells. They initiate signaling cascades by stimulating the infected cells and those nearby to produce cytokines.

2024年11月30日 · Interferons are man-made versions of proteins your body makes. These drugs work with your immune system to help it find and attack viruses and cancer. They can stop virus and cancer cells...

2018年2月16日 · Interferon is a protein released by the cells of the body when they are under attack from a virus or other invader. When interferon is released, it sets off a series of reactions in nearby cells...

2023年7月10日 · Interferons are currently used clinically to treat viral infections such as hepatitis C, cancers including non-Hodgkin’s lymphoma, and autoimmune diseases such as multiple sclerosis. This activity outlines the different types of interferons, namely interferon alpha, beta, …

2025年1月28日 · interferon, any of several related proteins that are produced by various types of cells in the body as a defensive response to viruses. They are important modulators of the immune response. Interferon was named for its ability to interfere with viral proliferation.

2025年2月8日 · The interferon pathway is a complex network of proteins and signaling molecules orchestrating a multifaceted response to viral infections. It is initiated by the production of interferons, signaling proteins released by host cells in response to pathogens.
