Interferon

Real World Example

Imagine you're trying to host a quiet dinner party, but uninvited guests keep trying to crash it. Interferon acts like a vigilant security guard that stops these unwanted guests (viruses) from entering and disrupting the event (the cell). Just as the security guard prevents party crashers from causing chaos, interferon prevents viruses from replicating and spreading within infected cells, ensuring the party (the cell's normal functions) can continue without interruption.
