Interferons

Question

Interferons
A) prevent viruses from leaving a cell.
B) prevent viruses from entering a cell.
C) bind to viruses and destroy them.
D) interfere with viral replication.
E) reduce macrophage chemotaxis to the infection.

Accepted Answer

Interferons interfere with viral replication by inducing antiviral responses in infected cells and neighboring cells. They do not prevent viruses from entering or leaving the cell, nor do they bind to and destroy viruses. Additionally, interferons can actually increase macrophage chemotaxis to the area of infection, rather than reduce it.
