Abstract
|
|
|
|
Calystegia dahurica (Herb.) Choisy is a natural product that has not been studied for efficacy or active ingredients. The purpose of this study is to investigate the activation effect of natural killer cells using a natural extract composition based on Calystegia dahurica (Herb.) Choisy extract (CDCE). We evaluated the activity of natural killer cells in natural products using PBMCs from healthy participants. All natural products were extracted with 50% ethanol. Based on the results of the cell viability assay, PBMCs of healthy participants were treated with extracts at various concentrations. Then, analysis was performed using flow cytometry to measure the cd107a surface expression of natural killer cells. As a result, treatment with a single extract of PBMCs increased the expression of cd107a in a concentration-dependent. Furthermore, it was confirmed that the treatment of the extract composition showed the highest expression of cd107a. In conclusion, it is expected that the extract composition containing CDCE according to this study can be used for prevention or treatment of cancer cells, tumor cells, and immune diseases.
