Expert Answer

Step 1

For the proper T cell activation different steps are required:

Antigen processing and presentation by APC (antigen presenting cell). It displays antigens as peptides bind to MHC protein. That is shown in the second image from the top.

Step 2

Specific binding of T cell receptor to the antigen. That means binding of CD4 coreceptor to MHC-II in T helper cells, and binding of CD8 coreceptor to MHC-I in T cytotoxic cells. That is shown in the third image from the top.

Step 3

Costimulation of  T cells by APC  through interaction ...
