WitrynaThe T-cell copies itself, making more T-cells to defeat the intruder. These T-cells that join the fight are called effector cells. When your immune system is working properly, these effector T-cells destroy the threat, helping rid you of infection and disease. Your T-cells continue to protect you even after the intruder’s gone.

WitrynaNaive and effector cells differ in their requirements for activation, with a higher threshold demanded of the naive cells (refer to Table 15-3). This is physiologically rational because the naive T cell should not be activated unless there is a significant need for it, but once the need has been demonstrated and antigen is present in ...
