Figure 5. Treatment-responsive patients with CRS without asthma also have defective NK cell functions.

The single asthmatic patient in the treatment-responsive (TR-CRS) group was excluded, thus yielding the asthma (−) TR-CRS group (n = 9). The PBLs from these patients and normal donors (N, n = 19) were stimulated and analyzed, as described in Figure 2. The two groups were compared in terms of the CD107a (A), IFN-γ (B) or TNF-α (C) expression by their NK cells. *P<0.05.
