Fig. 1From: Vδ1T Lymphocytes Expressing a Th1 Phenotype Are the Major γδ T Cell Subset Infiltrating the Liver of HCV-infected PersonsPhenotypic characterization of naive, memory and activated lymphocytes in the peripheral blood and liver of hepatitis C virus (HCV)-infected patients. (A–F) The percentage of naive (CD45RA+CD62L+), memory (CD45RO+CD62L−) and activated (HLA-DR+) cells was analyzed by flow cytometry. (A,B,C) The percentage of these cell subsets in peripheral blood mononuclear cells (PBMC) and (D,E,F) intrahepatic lymphocytes (IHL) compartments from a representative patient is shown. The percentage of naive, memory, and activated cells in blood (white bars) and liver (hatched bars) on 10 HCV+ patients are shown in the bottom graph. Data represent the arithmetic mean percentage ± standard deviation (SD). Significance refers to Student’s t-test. p-values are indicated as follows: * = p < 0.001.Back to article page
