IL2 and breast cancer: Additionally, the variation of the mean fluorescence intensity (vMFI) in the ASC group (vMFI = 582.12 ± 682.04) was significantly higher than the BC group (vMFI = 25.98 ± 24.83), but did not differ in relation to the BP group (vMFI = 25.33 ± 82.14) or the ASC-CA group (vMFI = 89.95 ± 167.85) (Figure 1d, vMFI was calculated by subtracting CD107a MFI of resting NK cells from CD107a MFI of IL-2 stimulated NK cells).
