Interferon response to an acute virus infection[/td]
<td align=left width="80%" colSpan=5>Interferons play an important role in the first line of defense against viral infections. They are part of the non-specific immune system and are induced at an early stage in viral infection – before the specific immune system has had time to respond.
<FONT face="Arial Narrow">Interferons are made by cells in response to an appropriate stimulus, and are released into the surrounding medium; they then bind to receptors on target cells and induce transcription of approximately 20-30 genes in the target cells, and this results in an anti-viral state in the target cells.
