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.

Cell viability (%) of tumor cell lines after incubation with Nidus Vespae (10, 100, 1000, 2500, 5000, and 10000 μg/mL) or control for 24 h. Data were analyzed by one-way ANOVA and presented as mean and standard deviation. No significant differences were observed between all concentrations; yet it showed increased tendencies of viability.

Data were analyzed by one-way ANOVA and presented as mean and standard deviation. No significant differences were observed between all concentrations; yet it showed increased tendencies of viability.

Mentions: The cytotoxicity of NVD on gastric tumor cells was tested by cell counting kit-8. There were no significant differences between all concentrations, although increased tendencies of viability were observed in Figure 1. It indicates that NVD does not lead to the SGC-7901, HGC-27, and NCI-N87 toxicities in the studied concentrations (10~10000 μg/mL).
