Interferons
Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.
<h3>What are Interferons ?</h3>
Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
- They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces
- So that T cells surveying the area can identify and eliminate the viral infection.
