We thank Silke Gotschy, Martina Hitzenbichler, and Sabine Mühlsimer for
their excellent technical assistance as well as Jessica Plewa, Michael
Becker, and Axel Unverzagt for assistance with human body donors. All PV
samples were received from patients who had given written informed
consent. A positive ethics vote was given for: PV1, University clinic
Lübeck (Az 12-178), PV2 University Clinic Budapest (249-12), PV3
University Clinic Gießen/Marburg (Studie 20/14). All patients suffered
from PV with mucocutaneous involvement. The study was supported by DFG

Cluster Precision Medicine in Chronic Inflammation (EXC 2167) from the
Deutsche Forschungsgemeinschaft to ES.
