The Immunomodulatory Effects of Nidus Vespae on Human Peripheral Blood Immune Cells In Vitro.

Zhu M, Ling Y, Qi Q, Zhang Y, Bao Y, Liu Y - Evid Based Complement Alternat Med (2015)

Bottom Line: Data showed that NVD has no significant inhibiting effects on gastric cancer cells growth.Nevertheless, it could obviously promote PBMC proliferation in a time- and concentration-dependent manner.After treatment with NVD, the CTL cytotoxicity against SGC-7901 was significantly greater than control.

ABSTRACT
Nidus Vespae has been used in traditional Chinese medicine (TCM) to treat various cancers, but the underlying mechanisms were not yet clarified. This study was to investigate the effect of Nidus Vespae decoction (NVD) on tumor cell viability and immunoregulating functions of human peripheral blood immune cells. The effects on tumor cell viability, peripheral blood mononuclear cell (PBMC) proliferation activity, and the tumor cell phagocytosis of monocytes were evaluated by cell counting kit-8. Tumor-killing activity of cytotoxic T lymphocyte (CTL) was analyzed by (51)Cr releasing assay. IgG production of B cells and cytokine (TNF-α and IL-6) secretion of monocytes were determined by ELISA method. Data showed that NVD has no significant inhibiting effects on gastric cancer cells growth. Nevertheless, it could obviously promote PBMC proliferation in a time- and concentration-dependent manner. After treatment with NVD, the CTL cytotoxicity against SGC-7901 was significantly greater than control. The TNF-α and IL-6 secretion of monocytes and the IgG production of B cells also increased remarkably. Furthermore, NVD could significantly promote the phagocytosis of monocytes on tumor cells. These results suggest that NVD appears to have an immunoenhancing effect on immune cells, indicating that Nidus Vespae is worth exploring for immunomodulatory effects in tumor treatment.

51Cr releasing assay of CTL cytotoxicity against SGC-7901 target cells. CTL cytotoxicity was compared between NVD treated CTL (■) and untreated controls (○) (n = 10). Comparisons were statistically significant as compared with untreated controls (P < 0.01). No significant differences were observed between different effector/target ratios. Data were analysed by two-way ANOVA and presented as mean and standard deviation.

fig3: 51Cr releasing assay of CTL cytotoxicity against SGC-7901 target cells. CTL cytotoxicity was compared between NVD treated CTL (■) and untreated controls (○) (n = 10). Comparisons were statistically significant as compared with untreated controls (P < 0.01). No significant differences were observed between different effector/target ratios. Data were analysed by two-way ANOVA and presented as mean and standard deviation.

Mentions: As shown in Figure 3, the cytotoxicity index of the CTL against SGC-7901 after treatment with NVD was 9.35%, 10.80%, and 10.25% for 10 : 1, 20 : 1, and 40 : 1, respectively, which were significantly greater than control (2.39%, 3.43%, and 3.28%, P < 0.01). No significant differences were observed between NVD treated CTL at different effector/target ratios and the untreated controls.
