Abstract

The current study aimed to investigate the distribution of memory and naïve T cell (TN) subsets in hepatitis B virus (HBV)‑infected patients at different immune stages and investigate the effect of interleukin 33 (IL‑33) on the regulation of the T‑cell subsets. The distributions of memory and naïve T cells were detected by flow cytometry. ELISA was conducted to assess the levels of IL‑4, IL‑5, IL‑10, IL‑12, interferon γ and tumor necrosis factor α. The expression levels of IL‑33 and HBV x protein (HBx) were measured by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively. By detecting TNs, central memory T cells (TCM) and effector memory T cells (TEM), it was identified that the proportions of TCM and TEM in CD4+ T cells were increased in patients with HBV. The trend observed for levels of CD8+ TCM and TEM was similar to that of CD4+ T cells in the immune tolerance and immune activation groups, however CD8+ TCM and TEM were significantly reduced in patients who underwent treatment. The CD8+ TEM cells appeared to be more sensitive to HBV activation and drug therapy. In addition, IL‑33 stimulation was observed to induce imbalances of CD8+ TN and CD8+ TEM, and while the imbalances were directly regulated by HBx, IL‑33 was not a key factor for the expression of HBx. CD8+ TEM cells may be a sensitive marker to assess the immune state of patients with HBV and the effect of clinical therapy. Treatment targeting IL‑33 may be a potential method to reverse HBV‑induced immune tolerance.
