Which of the following statements about memory B cells is correct?
A
Memory B cells are a type of T cell that helps activate other immune cells.
B
Memory B cells are only produced in response to bacterial infections.
C
Memory B cells are responsible for the immediate production of antibodies during the primary immune response.
D
Memory B cells can persist in the body for years, providing long-term immunity.
Verified step by step guidance1
Understand the role of memory B cells in the immune system. Memory B cells are a type of B lymphocyte that plays a crucial role in the adaptive immune response.
Differentiate between B cells and T cells. B cells are responsible for producing antibodies, while T cells have various roles, including helping activate other immune cells.
Recognize that memory B cells are not limited to responding to bacterial infections. They can respond to various pathogens, including viruses.
Clarify the difference between primary and secondary immune responses. Memory B cells are not responsible for the immediate production of antibodies during the primary response; instead, they facilitate a faster and more robust response upon re-exposure to the same antigen.
Identify the correct statement: Memory B cells can persist in the body for years, providing long-term immunity by quickly responding to previously encountered antigens.
