Which of the following occurs during an adaptive immune response?
Phagocytosis
Production of antibodies
Production of interferon
Production of defensins
The Correct Answer is B
A. Phagocytosis: phagocytosis is mainly an innate immune function (macrophages, neutrophils) though phagocytes can interact with adaptive immunity.
B. Production of antibodies: antibody production by plasma cells (B-cell derived) is a hallmark of the adaptive immune response.
C. Production of interferon: interferons are part of innate antiviral defenses and are produced early by infected cells and immune cells.
D. Production of defensins: defensins are innate antimicrobial peptides produced by epithelial cells and neutrophils, not a specific adaptive response.
