Q

the following are steps in the cell-mediated immune response. What is the correct sequence for these steps?

  1. several cycles of mitosis occur
  2. antigen is engulfed and presented by a macrophage
  3. cytotoxic T cells migrate to focus of infection
  4. T cells with specific receptors recognize the antigen
  5. T cells differentiate into cytotoxic T cells or T memory cells
  6. cytotoxic T cells release perforin and/or lymphotoxin
