Quick Summary

Alpha interferon is a protein produced by white blood cells that plays a crucial role in the body's defense against viruses. It works by interfering with viral replication and also helps regulate the immune response.123

Key Functions and Types

  • Antiviral Activity: Interferons signal to other cells to resist viral growth.2
  • Immune Regulation: They enhance immune surveillance, activate immune cells like natural killer (NK) cells, and promote the activity of macrophages and T cells.4
  • Types: While alpha interferon is produced by white blood cells, other types include beta interferon (from fibroblasts) and gamma interferon (from lymphocytes).32

Therapeutic Uses

Alpha interferon has been used to treat various diseases, including hairy-cell leukemia, Kaposi sarcoma, hepatitis B and C, and genital warts. It is often produced using recombinant DNA technology. However, interferon treatments can have significant side effects, such as flu-like symptoms and fatigue.453
