Protein tyrosine phosphatase non-receptor II: A possible biomarker of poor prognosis and mediator of immune evasion in hepatocellular carcinoma

Figure 5 Immune cell infiltration in high and low protein tyrosine phosphatase non-receptor 2 expression groups. ++: Interleukin (IL)-6⁺ T-cell, CD3⁺ T-cell, CD4⁺ T-cell and CD8⁺ T-cell infiltration in the high protein tyrosine phosphatase non-receptor 2 (PTPN2) expression group; +: IL-6⁺ T-cell, CD3⁺ T-cell, CD4⁺ T-cell, and CD8⁺ T-cell infiltration in the low PTPN2 expression group. IL: Interleukin; PTPN2: Protein tyrosine phosphatase non-receptor 2.
