HCV and HBV mono-infected patients display distinct patterns of DPT cells.

<p><b>A,</b> Correlation between the proportions of CD4^hiCD8^lo DPT cell subpopulations (1) in blood and liver of HCV mono-infected patients; other subpopulations did not significantly correlate. <b>B,</b> Correlation between the proportions of CD4^loCD8^hi DPT cell subpopulations (3) in blood and liver of HBV mono-infected patients; CD4^hiCD8^hi correlated to the same extent as CD4^loCD8^hi (respectively 2 and 3) in HBV-infected patients (not shown). Each dot represents the proportions in blood and liver for a patient; significance of Pearson's correlation was tested using a t-test. The numbers between brackets correspond to the quadrants set-up in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0020145#pone-0020145-g001" target="_blank">Figure 1A</a>, lower right panel.
