  • Materials and Methods
  • Fig. S1. IL-4 target genes are an appropriate negative control for IL-36 enrichment analyses, because there is no overlap between IL-4 and IL-36 signature genes.
  • Fig. S2. The pathways that underlie the pathogenesis of GPP are enriched within the IL-36 transcriptome.
  • Fig. S3. Mechanical trauma up-regulates IL-36 production by cultured keratinocytes.
  • Fig. S4. Proposed pathogenic model illustrating the role of IL-36 as an amplifier of TH17 signaling in psoriasis.
  • Fig. S5. In vivo IL-36 signaling blockade reduces the infiltration of IL-17–producing αβ T cells in imiquimod-induced psoriasiform dermatitis.
  • Fig. S6. The genes encoding the IL-36R subunits are expressed in PBMCs.
  • Fig. S7. Dose- and time-dependent effects of IL-36 cytokines in primary keratinocytes.
  • Fig. S8. Complete Western blots for Fig. 5E.
  • Table S5. Rare homozygous IL1RL2 variants observed in the Born in Bradford cohort.
