Immunomodulatory Effect of Flavonoids of Blueberry (Vaccinium corymbosum L.) Leaves via the NF-κB Signal Pathway in LPS-Stimulated RAW 264.7 Cells

Table 2

Effects of FBL on the viability of RAW 264.7 cells.

FBL (μg/mL)	500.00	250.00	125.00	62.50	31.25	15.63	7.81	3.91
Cell viability (%) (X ± S)	74.80 ± 4.59	83.15 ± 1.76	88.75 ± 1.78	101.50 ± 1.97	100.84 + 4.32	101.05 ± 3.68	100.58 ± 2.76	100.33 ± 3.45

Control groups were treated only with 1 μg/mL LPS; the cell viability in the control group (cells were treated by LPS) was set as 100%. FBL groups were treated with 1 μg/mL LPS and different concentrations of FBL. versus control group treated with only LPS.
