The correct sequence of events in the action of interferon is ________________.
1) viral infection of host cells causing rapid production and secretion of Type I IFNs
2) host cell produces antiviral proteins that can degrade viral RNA, inhibit protein synthesis and virion assembly and prevent viral gene expression
3) modification of neighboring cell's gene expression induces an antiviral state
4) binding of IFNs to receptors on uninfected neighboring cells

Question

Quizplus · Accepted Answer

The correct sequence starts with a viral infection leading to the production of Type I interferons (IFNs), followed by the binding of these IFNs to receptors on neighboring cells, which then alters the gene expression of these cells to induce an antiviral state, culminating in the production of antiviral proteins that inhibit various stages of viral replication.
