60 ± 2.01, t = 6.117, P < 0.05) (shown in Fig. 2). At present, there are no data examined whether IVIG therapy effected the NKG2D expression on CD8+T cells and CD3−CD56+NK cells in KD. In this preliminary study, the results showed that there was an upregulated tendency after treatment with IVIG,, although considerable samples was sustained low expression MG-132 datasheet of NKG2D, which might be related to relative short time to be revaluated after IVIG therapy. The levels of NKG2D expression on CD3−CD56+NKG2D+ NK cells were increased
in 20 children who received therapy with IVIG. The levels of NKG2D expression on CD8+T cells in 30 children with KD after IVIG treatment were detected to be higher than those before the therapy (shown in Fig. 3). The MFI of NKG2D expression on CD3−CD56+NKG2D+ NK cells was increased in 22 children who received therapy with IVIG. The MFI of NKG2D expression on CD8+T cells in 29 children with KD after IVIG
treatment was detected to be higher than those before the therapy (shown in Fig. 3). Rea1-time PCR was used to evaluate the mRNA levels of cytokines such as IL-1β, IL-6 and TNF-α. As shown in Fig. 4, compared with healthy controls, the expression levels of IL-1β (5.12E-01 ± 1.78E-01 versus 8.85E-02 ± 3.13E-02, t = 14.89, P < 0.05), IL-6 (4.22E-03 ± 2.31E-03 versus 1.72E-03 ± 1.35E-03, t = 5.944, P < 0.05) and TNF-α (1.19E-01 ± 5.12E-02 versus learn more 1.16E-02 ± 6.10E-03, t = 13.903, P < 0.05) were significantly upregulated during acute phase of KD. The levels Fenbendazole of IL-1β (1.06E-01 ± 5.09E-02, t = 13.768, P < 0.05), IL-6 (1.48E-03 ± 8.10E-04,
t = 7.590, P < 0.05) and TNF-α (3.03E-02 ± 2.48E-02, t = 10.469, P < 0.05) expression were decreased to some extents after therapy with IVIG. In addition, transcription levels of proinflammatory cytokines [IL-1β (6.12E-01 ± 2.19E-01 versus 4.59E-01 ± 1.26E-01, t = 2.576, P < 0.05), IL-6 (6.41E-03 ± 1.66E-03 versus 3.05E-03 ± 1.67E-03, t = 2.419, P < 0.05) and TNF-α (1.51E-01 ± 6.74E-02 versus 1.02E-01 ± 3.10E-02, t = 2.757, P < 0.05)] in KD-CAL+ patients with coronary artery lesion were detected to be higher than those in patients with KD-CAL−. It has been reported that IL-7 and IL-15 induce the expression of NKG2D on immunocompetent cells, and NKG2D can be downregulated on these cells by IL-12, TGF-β and IFN-γ [8-12] (Table 4). In this study, the plasma concentration of cytokines in KD was detected by ELISA. The serum concentrations of IL-7 and IL-15 in patients with KD were significantly lower compared with the concentrations in the healthy controls and the KD patients after IVIG therapy (P < 0.05). And the IFN-γ concentration in KD was higher compared with the concentration in the healthy controls and the KD patients after IVIG therapy (P < 0.05).
