Question: Discuss the pros and cons for a debate on Synthetic Biology, and some reasons why they are pros and cons. Explain your answer.
1. The costimulatory signal that is required for activation of T cells after TCR binding to presented antigen is the binding of CD28 on T cells to B7 on the antigen-presenting cell (APC).
2. The critical cytokine that a T cell will produce following its activation by signals from an antigen-presenting cell is Interleukin 2 (IL-2).
