Interferons secreted by virus-infected cells induce:
Show Hint
- antiviral response
- pro-viral response
- apoptosis
- cell proliferation
The Correct Option is A
Solution and Explanation
Step 1: Concept
Interferons (IFNs) are signaling proteins (cytokines) released by host cells in response to the presence of viruses.
Step 2: Meaning
They "interfere" with viral replication by alerting neighboring uninfected cells.
Step 3: Analysis
IFNs trigger the production of antiviral proteins in nearby cells, which inhibit protein synthesis and degrade viral RNA if the cell becomes infected.
Step 4: Conclusion
The primary physiological role of these molecules is to induce a systemic antiviral state. Final Answer: (A)
