- PCAT Question of the Day
Which of the following is not a component of the adaptive immune response?
A. B lymphocytes
B. CD8+ T lymphocytes
Click for Explanation
D is correct. Adaptive immunity is the branch of the immune response that recognizes and responds to specific pathogens. In contrast, innate immunity provides general, non-pathogen-specific protection. Adaptive immunity includes B lymphocytes, which produce antibodies (also termed immunoglobulins). T lymphocytes (both CD4+ and CD8+) are also a component of the adaptive immune response, but macrophages are part of innate immunity.
