Immune Regulation of RAW264.7 Cells In Vitro by Flavonoids from Astragalus complanatus via Activating the NF-κB Signalling Pathway

Figure 4

Effect of FAC on the secretion of CD40, CD80, and CD86. RAW264.7 cells were treated with different concentrations (0–10 μg/mL) of FAC in the absence or presence of 10 μmol/mL PDTC. From the left to right, secretion of CD40 (PB), CD80 (PE), and CD86 (FITC). After the cell surface factor was detected by flow cytometry, the results were expressed by histogram.
