मानवी पेशी विषाणूंचा तात्कालिक प्रादुर्भाव रोखण्यासाठी आणि अनैसर्गिक बदल झालेल्या पेशींची संख्यावाढ रोखण्यासाठी _____ तयार करतात.

The correct answer is Option A (Interferone).

Key Points:
• Innate Viral Defense System:
• Interferons (IFNs) are a group of signaling proteins (cytokines) produced and released by host body cells in immediate response to viral infection.
• Biological Mechanism:
• When a cell detects viral genetic replication, it secretes interferons to alert surrounding uninfected cells.
• The binding of interferon induces nearby cells to produce antiviral enzymes, degrades viral RNA, halts protein translation, and prompts major histocompatibility complex (MHC) presentation, simultaneously suppressing abnormal cellular proliferation.
• Other hormones listed have disparate roles: Insulin regulates blood glucose, somatostatin inhibits growth hormone release, and endotoxins are bacterial structural components.
• Hence, Option 1 (Interferone) is the correct immunological agent.
• Key Takeaway: Interferons are innate antiviral glycoproteins produced by cells to counter viral infection and limit abnormal cell proliferation.
