What cellular component does Granulysin primarily target?

• A. Viruses
• B. Bacteria
• C. Fungi
• D. Parasites

Answer: (B)

Granulysin is a protein released from cytotoxic T lymphocytes and natural killer (NK) cells, which plays a significant role in the immune response, particularly against certain pathogens. The primary target of Granulysin is bacteria. It has the ability to directly kill various types of bacteria, including intracellular pathogens, by disrupting their membranes. Granulysin also has antimicrobial properties, making it effective in defending the body from bacterial infections. In addition to its action on bacteria, Granulysin can also have some effects on other types of pathogens, but its most well-characterized function is its bactericidal activity. This understanding of Granulysin's role underscores the importance of effective immune mechanisms in controlling bacterial infections within the body.
