WebWhen an effector B cell (plasma cell) becomes activated it produces memory and effector B cells. 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. WebIn the germinal center early stage antibody-secreting B cells undergo isotype switching and transition into a plasma cell. Antibody production by B cells can quickly neutralize a potential infection. Once the infection is neutralized, B cells can become memory B cells, which exist in small numbers in the case of re-infection.
