Abstract:
Objective To detect the levels of Th1 and Th2 type cytokines of peripheral blood CD+4 T lymphocytes in the patients with cervical cancer in order to find out the laboratory evidence of tumor immunotherapy. Methods The peripheral blood lymphocytes were stimulated by stimulator in order to enhance expression of cytokines. Then specific fluorochrome-conjugated monoclonal antibody was added to be combined with its specific antigen. Results The level of IL-2 produced by Th1 cells were lower in patients of cervical cancer than those of normal controls, there were significant difference between them. But the level of IFN-? produced by Th1 cells had no significant change in patients of cervical cancer in comparison with normal controls. The levels of Th2 type cytokines such as interleukin-4(IL-4), interleukin-6(IL-6), interleukin-10(IL-10) were higher in patients of cervical cancer than those of normal controls, there were significant difference between them. Conclusion Th1/Th2 is imbalance in cervical cancer .Th1 type cytokines are inhibited, and Th2 type cytokines are relatively enhanced, so Th1/Th2 shifts to Th2. It may be the mechanism of tumor arising and transferring by immune escape from immunosurveillance.
