Abstract

Objective To investigate the affect of Echinococcus multilocularis protein mediated natural killer (NK) cell surface inhibitory receptor NK cell lectin-like receptor subfamily C member A (NKG2A) on the function of NK cells. Methods Peripheral blood samples were colleted from the participants for NK cell purification. An aliquate of 0.3 × 10 6 NK cells were resuspended in 100 μl RMPI 1640 medium, which was transferred into a 96-well plate. Four test groups were assigned, including blank control, negative control, E. multilocularia protein (Emp) group, and transforming growth factor-β 1(TGF-β1) group (positive control group). The blank conrol group underwent no further treatment. For the negative control group, 1 μl interleukin-12 (IL-12) and IL-15 (of 1 μg/ml each) were added, while the Emp group was treated with 1 μl IL-12 and IL-15 (at 1 μg/ml each) and 2.5 μl Emp (7 081 μg/ml); to the TGF-β1 group, 1 μl TGF-β1 (1 μg/ml) were added. RPMI 1640 medium was used to adjust the wells to a final volume of 104.5 μl when appropriate. Flow cytometry analysis was used to quantify the expression of NKG2A on NK cells and functional changes of NK cells and NKG2A +NK in secretion of cytokines [interferon-γ (IFN-γ), granzyme B, tumor necrosis factor α (TNF-α) and perforin] after culture stimulated for 24 hours in vitro. The data were analyzed using One-way ANOVA for difference analysis, and LSD or Dunnett test for comparison of the difference between groups. Results The percentage of NKG2A+NK cells in Emp group and TGF-β1 group were (3.40 ± 1.53)% and (3.00 ± 1.07)%, respectively, which were significantly higher than that in the negative control group (0.70 ± 0.56)% (P < 0.01). In the Emp group, the percentage of NK cells secreting IFN-γ was (42.38 ± 15.94)%, having was no significant difference compared to the negative control group (61.18 ± 7.18)% (P > 0.05). The percentage of NKG2A+NK cells secreting IFN-γ was (25.25 ± 11.57)%, which was lower than that in the negative control group (48.88 ± 12.78)% (P < 0.05); the difference in the percentage of NK and NKG2A+NK cells secreting granzyme B, TNF-α, and perforin was insignificant between the Emp griyog and negative control secreting NK cells and NKG2A+NK cells (P > 0.05). In the TGF-β1 group, the percentage of NK and NKG2A+NK cells secreting IFN-γ was (12.77 ± 2.56)% and (15.17 ± 6.34)%, respectively, which were lower than that in the negative control group (P < 0.01); there was no significant difference in the percentage of NK and NKG2A+NK cells secreting granzyme B, TNF-α, and perforin was forund between the Emp and negative control. Of the TGF-β1 group, the percentage of NK cells secreting IFN-γ upon stimulation was lower than that in the Emp group, but the difference was not statistically significant (P > 0.05). Conclusion Emp mediates up-regulation of the expression of NK cell surface receptor NKG2A and inhibits the function of NK cells secretging IFN-γ.
