Which of the following statements is/are true regarding T cytotoxic cell antigen elimination?
Released interferons by cancer cells or infected cells increases production of MHC II, increasing the likelihood that cytotoxic T cells will "seek and destroy" these cells. Once the threat has been detected by the T cell receptor, the cytotoxic T cell releases perforins that form pores in the target cell and granzymes, which enter through pores to trigger apoptosis. Interferons released by infected or cancer cells attract and activate cytotoxic T cells, while cytokines released by the cytotoxic T cells attract natural killer cells and macrophages. Following apoptosis by cytotoxic T cells, macrophages and natural killer cells clear the dead cells.
