Amazing discovery by Estonian
scientists
Figure 1. Protoarray reactivities to type I interferons (IFNs) and to known autoantigens. The
reactivities to  type I IFNs and  known APECED autoantigens. The Protoarray signals are
expressed as z-scores representing the number of SDs from the mean of combined control
samples. Positive-negative discrimination level (dark red line) was set at z = 3. Red circles
represent the samples with z > 3, gray circles are control samples.
