Upon iNKT-specific α-GalCer activation, BD patients displayed a non-significant trend to an increase in TNF production (BD us: 76.5% [IQR: 66.7–84]; BD stim: 87.5% [IQR: 78.2–99.1]; (p = .063), (Fig. 2E), with a tendency to higher cytokine release compared to DN subjects (p = .056; see above for DN values) (Fig. 2E). This evidence concerns the gene TNF and Behcet disease.
