Does Beta Interferon Suppress the Immune System?

Interferon proteins are normally considered virus-fighters, but scientists at The Scripps Research Institute (TSRI) have found evidence that one of them, interferon beta (IFNβ), has an immune-suppressing effect that can help some viruses establish persistent infections.

What does beta interferon do?

Beta interferon (sometimes referred to as interferon beta), released at the end of an immune attack, blocks the action of gamma interferon and helps to reduce inflammation and the body's immune reaction.

How does interferon affect immune response?

Interferons are proteins that are part of your natural defenses. They tell your immune system that germs or cancer cells are in your body. And they trigger killer immune cells to fight those invaders. Interferons got their name because they "interfere" with viruses and keep them from multiplying.
