All T cell effector functions involve the interaction of an armed effector T cell with a target cell displaying specific antigens. The effector proteins released by these T cells are focused on the appropriate target cell by mechanisms that are activated by recognition of antigens on the target cell. The different types of effector T cell are specialized to deal with different types of pathogen, and the effector molecules they are programmed to produce cause distinct and appropriate effects on the target cell.
