Figure 3.
Average frequency of CD3+, CD4+, CD8+ and CD20+ lymphocytes, and FOXP3, TGF-β1, and granzyme B-positive cells in cases 1–5 within the portal area. For the enumeration of positive mononuclear cells, all mononuclear cells were counted in two microscopic fields of the portal tract, twice. For each sample, the mean percentage of positive cells was used. In FOXP3, there was a significant difference before IFN therapy and after HCC development (P=0.0084), as determined by the Wilcoxon test. No significant differences were identified in levels of CD3 (P=0.46), CD4 (P=0.46), CD8 (P=0.60), CD20 (P=0.60), TGF-β1 (P=0.46) and granzyme B (P=0.60) before IFN therapy compared with after HCC development. FOXP3, forkhead box P3; TGF-β1, transforming growth factor-β1; IFN, interferon; HCC, hepatocellular carcinoma; SVR, sustained virological response.
