Question

Name the cell which is recruited first at the place of infection.

• A. NK cells
• B. Basophils
• C. Neutrophils
• D. Macrophages

Hint:

Neutrophils are essential for the early stages of immune defense, quickly responding to infections by migrating to the site and ingesting pathogens.

Answer 1

The Correct Option is C

Let's analyze each option:
(1) NK cells (Natural Killer cells): NK cells are involved in killing infected cells, but they are not the first to be recruited to the site of infection. Hence, this is not the correct answer.
(2) Basophils: Basophils play a role in allergic reactions and inflammation, but they are not the first cells to be recruited during an infection. This is not the correct answer.
(3) Neutrophils: Neutrophils are the first cells to be recruited to the site of infection. They are part of the innate immune response and efficiently respond to infection by engulfing and killing pathogens. Therefore, this is the correct answer.
(4) Macrophages: Macrophages are recruited after neutrophils. They play an important role in clearing infections and immune regulation but are not the first to respond.
Conclusion: The correct answer is Option 3: Neutrophils as they are the first cells recruited to the site of infection.
