Here's why:
* Interferons are a group of signaling proteins produced by the immune system in response to viral infections. They act as messengers, alerting nearby cells to the presence of a virus and triggering antiviral responses.
* Antiviral Effects: Interferons work by interfering with the viral life cycle. They do this by:
* Inhibiting viral protein synthesis: Interferons can block the production of viral proteins essential for replication.
* Degrading viral RNA: Interferons can trigger the breakdown of viral genetic material (RNA).
* Enhancing immune cell activity: Interferons can boost the activity of immune cells like natural killer (NK) cells, which directly destroy virus-infected cells.
Therefore, interferons are crucial players in the body's defense against viral infections.
