Discussion
What type of B cell remains dormant in the body, but can respond rapidly if the same antigen appears again?
Answer: B
Correct answer: Memory cells
Memory cells are the long-lived survivors of a response. They persist for years without secreting antibody, and on meeting the same antigen again they mount a response that is faster, larger and of higher affinity than the first - which is what vaccination is for, and why most childhood infections are had only once.
