PD-1 Expression and Function of T-Cell Subsets in TILs From Human Lung Cancer.

On the basis of the autologous tumor-infiltrating lymphocytes (TILs) or genetically modified TILs for adoptive cell therapy have received more attention. Programmed cell death protein 1 (PD-1) expression on the T cells exert complex response during the tumor immune response. But the composition and function of PD-1T-cell subsets in TILs from human lung cancer still limited.

Effects of Glycogen Synthase Kinase-3β Inhibitor TWS119 on Proliferation and Cytokine Production of TILs From Human Lung Cancer.

The canonical Wnt-β-catenin signaling pathway arrests the differentiation of T cells and plays an important role in phenotypic maintenance of naive T cells and stem cell-like memory T cells in human peripheral blood, but its effect on tumor-infiltrating lymphocytes (TILs) from non-small cell lung cancer is little known. In this study, we showed that glycogen synthase kinase-3β inhibitor TWS119 has different effects on CD4 and CD8 T cells in TILs. TWS119 preserved the expansion of naive T cell and CD8 stem cell-like memory T cells, and induced CD8 effector T-cell proliferation in TILs.

The distribution and function of human memory T cell subsets in lung cancer.

The distribution and function of T lymphocytes in human lung cancer remain limited. In this study, we investigated the properties of human T cell subsets in the blood of non-small cell lung cancer (NSCLC) patients. We found a relatively normal level of CD4+ subsets in the blood of NSCLC patients, but CD8+ effector T cells increased and CD8+ effector memory cells declined compared to the healthy donors.

The Characteristics of Naive-like T Cells in Tumor-infiltrating Lymphocytes From Human Lung Cancer.

Adoptive cell therapy using autologous tumor-infiltrating lymphocytes (TILs) or genetically modified lymphocytes from TILs is a new effective approach, but the application of TIL immunotherapy is still limited in many solid tumors. Knowledge of the classification and function of TILs is important to develop personalized immunotherapy with TILs in non-small lung cancer (NSCLC). In this study, we show the characteristics of T-cell subsets in TILs isolated from NSCLC.

The Distribution of Human Stem Cell-like Memory T Cell in Lung Cancer.

Human stem cell-like memory T (Tscm) cells are long-lived, self-renewing memory lymphocytes that can differentiate into effector cells and mediate strong antitumour response in murine model. The distribution and function of Tscm cells in human lung cancer remain unknown. In this study, we investigated the properties of human Tscm cells in the blood and lymph node of non-small cell lung cancer (NSCLC) patients.
