Cytotoxic T cells are rapid killers of virally infected cells. Within minutes of the interaction of a cytotoxic T cell with a target cell, the program of apoptosis in the target cell is initiated, and the T cell can move on to a new target. Which of the following accurately describes key steps of this process? Answer choices: 1. Perforin and granzymes are only active in virally infected cells. 2. Perforin and granzymes are released from pre-formed cytotoxic granules at the interface between the T cell and target cell. 3. Granzymes cleave cell surface proteins, which induces the extrinsic apoptotic pathway in the target cell.
