Answer to Question #90468 in Cell Biology for Ahmad

Question

Fever stimulates cells infected by viruses to produce interferon. How does interferon affect our ability to resist infection?

Choices are;

it inhibits viral infection of uninfected cells


it stimulates macrophages to phagocytize viruses

it enhances antibody production by T cells of the adaptive immune system

it resets the body's thermal set point

Answer 1

It inhibits viral infection of uninfected cells.

Interferon is produced by infected cells and is released into the extracellular space. It binds receptors on uninfected cells and stimulates the production of antiviral regulatory proteins and enzymes that degrade viral nucleic acid and suppress the infection.
