I have found 2 different methods in which T cells are activated, which one is correct?

1) T HELPER cell has receptors which are complimentary to antigen so it binds to it, which causes other T cells to be activated and divide by mitosis to produce clones.
T Helper cell -> T cell -> clones

2) T cell has receptors which are complementary to antigen, so it binds to it, which causes that T cell activate and to divide by mitosis and produce clones.
T cell -> clones

2 is correct. T helper cells stimulate the activation of B cells and cytotoxic T cells, not regular T cells.

If the question is how generally T cells are activated then its simply when an antigen activates an immune response. Antigen presentation helps them find the affected cell, and THEN specific ones are selected and then they divide by mitosis and differentiate into T help and T killer. T helper stimulate the B cells to carry out phagocytosis. T killer kill the affected body cells, by releasing hydrogen preoxide.
