HLA-DPB1 and hepatocellular carcinoma: With GEPIA2 analysis of SGOL1 expression level with biomarkers of Treg cells (STAT5B, CCR8, and IL2RA), CD8+ T cells (CD8A and CD8B), M2 macrophages (CD163, VSIG4, and MS4A4A), neutrophils (ITGAM and CCR7), and dendritic cells (DCs; HLA-DPB1, CD1C) in HCC tissues, a significantly positive correlation was found between SGOL1 expression level and the above-mentioned biomarkers of immune infiltrating cells (Figure 7).
