What are the differences between a b cell and a memory b cell?

Answer:
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen.



A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen.

They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
