S100A9 and psoriasis: Fig 5B illustrates that the infiltration level of Gamma delta T cell, Type 17 T helper cell, Regulatory T cell and CD56dim natural killer cell was significantly linked to S100A12, CXCL8, IL1RN, S100A9, CXCL10, MMP1, CXCL1, FPR1, CXCR2, and S100A8 in CD samples of GSE102133. The presence of S100A12, CXCL8, IL1RN, S100A9, CXCL10, MMP1, CXCL1, FPR1, CXCR2, and S100A8 proved to be significantly interrelated with the infiltration level of Activated dendritic cell, Macrophage, and Neutrophil in Psoriasis samples in GSE111889 (Fig 5C).
