Question

Quizplus · Accepted Answer

Interferon triggers the production of viral-blocking enzymes by cells that have not yet been invaded by viruses. It is a type of cytokine that is released by infected cells and signals neighboring cells to prepare for an infection. Interferon does not directly break down viral mRNA or inhibit protein synthesis, but it does activate enzymes that prevent viral replication. The secretion of interferon is not known to be decreased during exercise.
