B and T Cell Effector and Memory Cell Differentiation

Upon activation T and B cells differentiate into effector cells that perform critical effector functions such as producing cytotoxic antipathogen molecules and antibodies, respectively. They also migrate to the site of infection and produce chemokines to recruit additional immune cells to eliminate infected cells. After successful completion of infection, a small fraction of the cells develop into long-lived memory T and B cells that protect against reinfection.
