Adoptively transferred tumor-specific T cells stimulated ex vivo using herpes simplex virus amplicons encoding 4-1BBL persist in the host and show antitumor activity in vivo.

4-1BB is a T-cell costimulatory receptor which binds its ligand 4-1BBL, resulting in prolonged T cell survival. We studied the antitumor effects of adoptively transferred tumor-specific T cells expanded ex vivo using tumors transduced with herpes simplex virus (HSV) amplicons expressing 4-1BBL as a direct source of antigen and costimulation. We constructed HSV amplicons encoding either the 4-1B...

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...

Arteether 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 ...

Targeting 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...

Harnessing the Effect of Adoptively Transferred Tumor-Reactive T Cells on Endogenous (Host-Derived) Antitumor Immunity

Adoptive T cell transfer therapy, the ex vivo activation, expansion, and subsequent administration of tumor-reactive T cells, is already the most effective therapy against certain types of cancer. However, recent evidence in animal models and clinical trials suggests that host conditioning interventions tailored for some of the most aggressive and frequent epithelial cancers will be needed to m...
