Bottom Line: This study aimed to examine the expression of immune suppression factors and the mechanisms of antitumor effects of cord blood dendritic cells (DCs) stimulated by soluble cluster of differentiation 40 ligand (sCD40L) and cytokines in vitro in ovarian cancer patients.Expression levels of IL-10 and TGF-β genes in the peripheral blood of ovarian cancer patients were significantly increased compared with patients with benign ovarian tumors (P < 0.05).A variety of cytokines in combination with sCD40L can promote the proliferation of cord blood-derived DCs and induce their maturation as well as stimulating a specific antitumor response.

ABSTRACT

Objective: This study aimed to examine the expression of immune suppression factors and the mechanisms of antitumor effects of cord blood dendritic cells (DCs) stimulated by soluble cluster of differentiation 40 ligand (sCD40L) and cytokines in vitro in ovarian cancer patients.

Methods: The expression levels of interleukin (IL)-10 and transforming growth factor (TGF)-β messenger RNA in peripheral blood were detected by reverse transcription polymerase chain reaction; expression levels of CD80 and CD86 in DCs stimulated by sCD40L were detected using flow cytometry and confocal laser scanning microscopy.

Results: Expression levels of IL-10 and TGF-β genes in the peripheral blood of ovarian cancer patients were significantly increased compared with patients with benign ovarian tumors (P < 0.05). The expression levels of CD80 and CD86 in DCs cultured in the granulocyte-macrophage colony-stimulating factor + IL-4 + stem cell factor + Flt-3 ligand + sCD40L group were significantly increased compared with those in the control group, as assessed by flow cytometry and confocal laser scanning microscopy (P < 0.05).

Conclusion: A variety of cytokines in combination with sCD40L can promote the proliferation of cord blood-derived DCs and induce their maturation as well as stimulating a specific antitumor response.

Mentions: FCM revealed that, after 7 days of culture, the expression levels of CD80 and CD86 on the surface of DCs induced by GM-CSF+IL-4+SCF+Flt-3l+sCD40L were 61.510% ± 1.163% and 78.160% ± 1.810%, respectively; these were significantly higher than in other groups (P < 0.05). No significant difference was observed in the expression levels of CD80 and CD86 molecules on the surface of DCs between the GM-CSF+IL-4+TNF-α- and GM-CSF+IL-4+SCF+Flt-3l+TNF-α-treated groups (P > 0.05). However, expression levels of CD80 and CD86 in both groups were significantly higher than in the GM-CSF+IL-4 control group (P < 0.05) (Figure 3 and Table 2).
