Dendritic cells strongly boost the antitumor activity of adoptively transferred T cells in vivo.
Dendritic cells (DCs) have been well characterized for their ability to initiate cell-mediated immune responses by stimulating naive T cells. However, the use of DCs to stimulate antigen-activated T cells in vivo has not been investigated. In this study, we determined whether DC vaccination could improve the efficacy of activated, adoptively transferred T cells to induce an enhanced antitumor i...
متن کاملTargeting STAT3 in adoptively transferred T cells promotes their in vivo expansion and antitumor effects.
Adoptive cell therapy with engineered T cells to improve natural immune response and antitumor functions has shown promise for treating cancer. However, the requirement for extensive ex vivo manipulation of T cells and the immunosuppressive effects of the tumor microenvironment limit this therapeutic modality. In the present study, we investigated the possibility to circumvent these limitations...
متن کاملDendritic Cells in Irradiated Mice Trigger the Functional Plasticity and Antitumor Activity of Adoptively Transferred Tc17 Cells via IL12 Signaling.
PURPOSE The adoptive cell transfer (ACT) of CD8(+) T cells is a promising treatment for advanced malignancies. Lymphodepletion before ACT enhances IFNγ(+)CD8(+) T cell (Tc0)-mediated tumor regression. Yet, how lymphodepletion regulates the function and antitumor activity of IL17A(+)CD8(+) T cells (Tc17) is unknown. EXPERIMENTAL DESIGN To address this question, pmel-1 CD8(+) T cells were polar...
متن کاملHematopoietic stem cells promote the expansion and function of adoptively transferred antitumor CD8 T cells.
Depleting host immune elements with nonmyeloablative regimens prior to the adoptive transfer of tumor-specific CD8(+) T cells significantly enhances tumor treatment. In the current study, superior antitumor efficacy was achieved by further increasing the intensity of lymphodepletion to a level that required HSC transplantation. Surprisingly, the HSC transplant and not the increased lymphodeplet...
متن کاملArteether Exerts Antitumor Activity and Reduces CD4+CD25+FOXP3+ T-reg Cells in Vivo
Background: Chemo-immunotherapy is one of the new achievements for treatment of cancer, by which the success of anti-cancer therapy can be increased. In vitro studies have been shown that Arteether (ARE) induces apoptosis in tumor cells, but not in normal cells. Objective: To investigate the cytotoxic and immunomodulatory properties of Arteether in-vivo and in-vitro. Methods: In this study, we ...
