naive cell definition
Naive B cell. A naÃ¯ve B cell is a B cell that has not been exposed to an antigen. Once exposed to an antigen, the naÃ¯ve B cell either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound. Plasma cells do not last long in the circulation, this is in contrast to memory cells that last for very long periods of time.
