_______ Continue to Produce Small Amounts of Antibody for Years

Question

_______ continue to produce small amounts of antibody for years after an infection.
A) Memory T cells
B) Macrophages
C) T cells
D) Memory B cells

Accepted Answer

Memory B cells are a type of white blood cell that are produced after an infection and "remember" how to produce antibodies against the specific pathogen that caused the infection. They continue to produce small amounts of antibody for years, providing long-term immunity against that pathogen. Memory T cells also play a role in immunity, but do not directly produce antibodies. Macrophages are important for phagocytosis and antigen presentation, but do not produce antibodies.
