Netherton syndrome (NS) is a rare skin disease caused by loss-of-function mutations in the serine peptidase inhibitor Kazal type 5 (SPINK5) gene. Disease severity and the lack of efficacious treatments call for a better understanding of NS mechanisms. Here we describe a viable, Spink5 conditional knock-out (cKO) mouse model, allowing to study NS progression. Using comparative transcriptomics and proteomics, we determine a disease molecular profile conserved in mouse models and NS patients. Spink5 cKO mice and NS patients share skin barrier and inflammation signatures defined by up-regulation of proteases, IL-17, IL-36, IL-20 family cytokines. Furthermore, we show that systemic inflammation in Spink5 cKO mice is associated with thymic atrophy and is driven by innate immunity and IL-17/IL-22 signaling. By comparing skin transcriptomes and proteomes, we uncovered several putative substrates of tissue kallikrein-related proteases (KLKs), demonstrating that KLKs can proteolytically regulate IL-36 pro-inflammatory cytokines. Our study thus provides a conserved molecular framework for NS disease, adding new insights into its mechanisms and therapeutic targets.
