| Abstract
|
| [Objective] To study the enhancing effect of super-antigen SEA on human peripheral blood monocytes (PBMC) in killing breast cancer cells (MCF-7). [Methods] PBMC was separated by gradient centrifugation from human peripheral blood, then different concentrations of super-antigen SEA, 0.01, 0.1, 1,10mg/L were added and Co-incubated with MCF-7 in plate of 96 wells for 24,48 and 72 h. Then the cytotoxicity on tumor was detected. [Results] With the increase of time, the cytotoxicity on tumor induced by SEA was enhanced. The tumor-cytotoxicity effect was the strongest when stimulated PBMC with super-antigen SEA of 10 kg/L at 72 h later.[Conclusion] Super-antigen SEA can enhance the anti-cancer effect of human peripheral blood mononuclear cells (PBMC). |
