Activated PBMCs from a healthy control donor were used as a calibrator and arbitrarily set as a CD3, CD158e/KIR3DL1, CD158k/KIR3DL2 and T-plastin expression level of 1. The middle bar in each group represents the median of that group, (a) The median level of CD3 is higher in the SS group (P=0.0133) (left). CD158k/KIR3DL2 mRNA expression is highly overexpressed in SS versus EID skin samples (P<0.0001) (middle). By contrast, T-plastin transcript quantification is not discriminant between SS and EID (P=0.8421) (right), (b) Raw data (relative transcript expression ×100), showing a significant overexpression of CD158k/KIR3DL2 mRNA but not T-plastin in SS (left) versus EID (right) skin samples. All data points represent the average of duplicate tests.
