Which antimicrobial protein is primarily responsible for triggering inflammation during the immune response?

• A. Histamine
• B. Interferon
• C. Complement
• D. Lysozyme

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the role of each listed molecule in the immune response. Histamine is a compound involved in allergic reactions and vasodilation, but it is not an antimicrobial protein.
2. Step 2: Recognize that Interferons are proteins that help interfere with viral replication inside host cells, acting as signaling molecules rather than directly triggering inflammation.
3. Step 3: Know that Lysozyme is an enzyme that breaks down bacterial cell walls, providing antimicrobial activity but not primarily responsible for triggering inflammation.
4. Step 4: Identify that the Complement system consists of a group of antimicrobial proteins that, when activated, enhance inflammation by recruiting immune cells and promoting the inflammatory response.
5. Step 5: Conclude that among the options, the Complement system is the antimicrobial protein complex primarily responsible for triggering inflammation during the immune response.
