Abstract
Background
CD8+Foxp3+ T lymphocytes have been detected in tumors. However, the distribution, phenotypic features, and regulation of these cells in gastric cancer remain unknown.
Methods
The levels of CD8+Foxp3+ T lymphocytes in the peripheral blood, tumor-draining lymph nodes, non-tumor tissues, and tumor tissues of patients with gastric cancer were detected by flow cytometry. Foxp3 induction in CD8+Foxp3− T cells was investigated in vitro. The suppressive function of CD8+Foxp3+ T lymphocytes was analyzed by their effect on CD4+ T-cell proliferation and IFN-γ production. The percentages of CD8+Foxp3+ T lymphocytes were evaluated for the association with tumor stage.
Results
The frequency of CD8+Foxp3+ T lymphocytes in tumor tissues was significantly higher than that in non-tumor tissues, and similar results were also observed in tumor-draining lymph nodes compared with peripheral blood. Most intratumoral CD8+Foxp3+ T lymphocytes were activated effector cells (CD45RA−CD27−). TGF-β1 levels were positively correlated with the frequency of CD8+Foxp3+ T lymphocytes in tumor tissues, and in vitro TGF-β1 could induce the generation of CD8+Foxp3+ T lymphocytes in a dose-dependent manner. Furthermore, intratumoral CD8+Foxp3+ T lymphocytes suppressed the proliferation and IFN-γ production of CD4+ T cells. Finally, intratumoral CD8+Foxp3+ T lymphocytes were significantly increased with tumor progression in terms of tumor-node-metastasis (TNM) stage.
Conclusions
Our data have shown that increased intratumoral CD8+Foxp3+ T lymphocytes are associated with tumor stage and potentially influence CD4+ T-cell functions, which may provide insights for developing novel immunotherapy protocols against gastric cancer.
