ABSTRACT
AIM:
To evaluate the immunopotentiation of novel adjuvant SWZY on the cancer vaccine of poorly immunogenic melanoma.METHODS:
C57BL/6 mice immunized with inactivated D5 melanoma cells were divided into 6 groups the control without adjuvants, with FCA, FCA+IL-2+GM-CSF, FIA+IL-2+GM-CSF, FIA+SWZY, and FIA+SWZY+IL-2+GM-CSF. Three days after completion of immunization, DTH response, specific killing activity of splenocytes and the level of IFN-gamma and IL-10 in serum and splenocytes' culture supernatant were assayed in half of the mice in each group. The rest were subject to live D5 tumor cell challenge. Three weeks after tumor inoculation, the same immunological parameters were measured.RESULTS:
DTH response, splenocytes' killing activity of all the experimental groups were markedly higher than those in the control group (P<0.05), but decreased as the tumor grew larger. The level of IFN-gamma in serum or splenocyte culture supernatant of each experimental group was significantly higher than that of the control (P<0.05) before tumor formation, whereas IL-10 level was lower than that of the control (P<0.05). After tumor formation, the level of IFN-gamma in all groups decreased while that of IL-10 increased in general, but the levels of IFN-gamma and IL-10 in group FCA and FIA+SWZY didn't change very much.CONCLUSION:
All kinds of adjuvants can enhance the cell-mediated immune response against poorly immunogenic tumor to some extent. The novel adjuvant SWZY can strengthen immunoresponses similar to FCA. With few harmful side-effect, SWZY might be a promising adjuvant for cancer vaccine.
