Astragaloside III significantly elevate expression of NKG2D and IFN-γ in NK cells in vitro. A, B, Representative dot plots show the expression of NKG2D (A) and IFN- γ (B) on NK cells after stimulated with different concentrations of Astragaloside III (gated on CD49+ CD3- cells). C, D, Statistical analysis of the frequencies of IFN- γ (C) and NKG2D (D) expression on NK cells in control and different dose of Astragaloside III stimulation groups (0, 4, 12, 20, 40 nM). All data are presented as the means ± standard errors. ** P < 0.01.
