Place the events of T cytotoxic cell activation in chronological order: Active T cytotoxic cells bind to infected cell displaying a foreign antigen. Activated T helper cells sensitized to the same antigen binds to the T cytotoxic cell and releases interleukins. Active T cytotoxic clones and memory cells formed. Cytotoxic cell secretes perforins. T cytotoxic cell receptor binds to foreign antigen and a MHC-I molecule. T cytotoxic cells proliferate. Lysing of infected cell.

The following are steps in the cell-mediated immune response. Put them in the correct order. 1. Cytotoxic T cells find viral-infected cell and release perforin and granzymes. 2. Antigen is engulfed and presented by a dendritic cell w/MHC I complex. 3. APC's secrete cytokine which causes T cells to differentiate into Th1. 4. Cytotoxic T cells and memory T cells are formed. 5. Th1 secrete cytokine which triggers Tc cells to undergo clonal expansion.
