The list of the DEG in common in the 4 studies (Table S2) contains many genes known to be upregulated in psoriasis, such as IFNγ-regulated genes STAT-1, STAT-3 and MX1; antimicrobial peptides (beta defensin 4, lipocalin 2, S100A7); and pro-inflammatory proteins such as IL-8, CXCL1, IL-1F9, TNFSF10/TRAIL. The gene discussed is IL36G; the disease is psoriasis.
