Which of the ff causes memory cells to convert to plasma cells?

  • A. An organ transplant
  • B. Re-exposure to a specific antigen
  • C. Release of lymphokines
  • D. Initial exposure to an antigen
Correct Answer: B

Rationale: The correct answer is B: Re-exposure to a specific antigen. Memory cells are formed after initial exposure to an antigen. Upon re-exposure to the same antigen, memory cells quickly recognize and respond, converting into plasma cells to produce antibodies. This process is known as secondary immune response.

Incorrect choices:
A: An organ transplant - Organ transplant does not involve the conversion of memory cells to plasma cells.
C: Release of lymphokines - Lymphokines are signaling molecules secreted by immune cells but do not directly cause memory cells to convert to plasma cells.
D: Initial exposure to an antigen - Initial exposure to an antigen leads to the formation of memory cells, not their conversion to plasma cells upon re-exposure.
