Answer #1
  • Compliment dependent cytotoxicity
  • CD4 th2 + cells

Tumor rejection is primarily mediated by T lymphocytes, although antibodies can also be involved and cause Antibody Dependent Cellular Cytotoxicity (ADCC) or Compliment Dependent Cytotoxicity (CDC). Antibodies cause a anti-tumor activity by interfering with growth controlling mechanisms.  

CD8+ and CD4+ lymphocytes play roles in cell mediated anti-tumor responses. CD4+ cells produce lymphokines that expand cytolytic T cells and activate macrophages and natural killer cells with anti-tumor activity. Tumor destruction is primarily mediated by Th1 type response, involving CTL and lymphokines and it may be inhibited by Th2 type lymphokines.

There is evidence that cytotoxic T lymphocytes (T cells) participate in controlling tumor growth and that they can be harnessed to use the body's immune system to treat cancer. One study investigated the use of a T cell-engaging antibody, blinatumomab, to recruit T cells to control tumor growth. The data below are T cell counts (1000 per microliter) at baseline (beginning of the study) and after 20 days on blinatumomab for 6 subjects in the study. The difference (after 20...
