A memory B cell lasts for a long time so if in the future the pathogen comes back it can proliferate effector and memory cells. A effector B cell on the other hand proliferates antigens immediately to fight off the current infections.
WebSep 1, 2008 · Early B-cell development is characterized by the ordered rearrangement of Ig H and L chain loci, and Ig proteins themselves play an active role in regulating B-cell development. 31 Pivotal to understanding how early B-cell development is regulated was the discovery of surrogate L chains (SLCs).
