Figure 2.
Differences of phenotypic marker expressions on the Tregs in chronic hepatitis B patients and healthy individuals. (a) Histograms represented the frequency of CCR4, CCR5, CCR7, Ki67, and Tim-3 expression in Tregs. One representative experiment of gating on CD4+FoxP3+ population was shown. The isotype-matched antibodies were used as controls. (Gray area represents isotype-matched antibody, blue line represents HBV patient, and red line represents healthy control). (b) Frequency of Helios expressing Tregs of chronic HBV-infected patients in inflammatory phases and healthy individuals. (c) The proportion of CCR4, CCR5, CCR7, Ki67, and Tim-3-expressing Tregs within the CD4+FoxP3+T cells was shown. Error bars denote the mean ± standard deviation are presented. *p < 0.05, **p < 0.01, ***p < 0.001.
