7What process involves the production of more activated cytotoxic T cells?
Clonal expansion
8What is the difference between memory T cells and cytotoxic T cells?
Memory T cells do not need to interact with APCs to become activated.
9How is the result of clonal expansion of activated B cells different than or similar to clonal expansion of T cells?
Clonal expansion of activated B cells results in the production of memory B cells and plasma cells,
whereas the clonal expansion of activated T cells results in the production of memory T cells and cytotoxic T cells.
