antibody mediated immunity
Involved in active killing
Produced by lymphocytes
Circulate in blood
Cell surface marker CD8

Primary immune response makes activated effector cells and memory cells
Cell surface marker CD4
antibodies (immunoglobulins)
With secondary immune response, memory T-cells and B-cells recognize and bind
There are no effector cells or antibodies for days
effector cells and immune cells are created within hours
release cytokines that later help to activate more immune cells
