Effector

... no activation) the cells multiply manyfold and quickly adapt the CD45RO+ phenotype, which indicates that they have become memory cells (central or effector), which is basically the final step of the T cell maturation cycle. The whole process is very complex, however, and it includes several other ...

... separate RTEs from "normal" naive T cells. RTEs mature into normal naive cells, and after antigen recognition they divide and gain their effector function (and switch from CD45RA+ to CD45RO+ among some other changes). T cells regularly circulate between lymphatic tissues and blood, so ...

... on the TCR signaling, prevaling cytokine environment, and cell-cell interactions, the memory cells can be divided to central memory cells or effector memory cells, which in turn can acquire a Th1, Th2, or Th17 effector phenotype.

... in a sense that they are yet to encounter their specific antigen in the periphery. Furthermore, they are not yet deviated into any T helper or T effector subtype. What exactly determines the final outcome of the T cell phenotype is still unclear, but it seems it involves regulatory T cells, APC ...
