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 …

Feb 16, 2018 · 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...

Mar 13, 2025 · An interferon is 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.

Jul 10, 2023 · This activity outlines the different types of interferons, namely interferon alpha, beta, and gamma. It discusses the pharmacological properties of different interferons, their medical uses, methods of administration, potential adverse effects, and other properties.

Nov 30, 2024 · 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 …

Interferons are the natural protein molecules secreted inside the cell, which are non-dialyzable, non-sedimentable and poorly antigenic. Interferons are the secretary proteins produced by the host cell in response to any attack by the foreign body or extracellular stimuli.

Interferon was discovered by Alick Isaacs and Jean Lindenmann in 1957. It was originally thought that interferon could be used as a general anti-viral agent and in anti-cancer therapy. There are many different types of interferons, now known as ...

The interferons (IFN)s are a family of cytokines with antiviral, antiproliferative, and antitumor activities, as well as immunomodulatory effects on the innate and adaptive immune responses (Lengyel, 1982; Pestka et al., 1987).

Feb 8, 2025 · 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.
