Abstract
Recently, we have developed a novel genetic platform for improving dendritic cell (DC) induction of peptide-specific CD8 T cells, based on membrane-anchored β2-microglobulin (β2m) linked to a selected antigenic peptide at its N-terminus and to the cytosolic domain of toll-like receptor (TLR)4 C-terminally. In vitro transcribed mRNA transfection of antigen presenting cells resulted in polypeptides that efficiently coupled peptide presentation to cellular activation. In the present study, we evaluated the immunogenicity of such constructs in mRNA-transfected immature murine bone marrow-derived DCs. We show that the encoded peptide β2m-TLR4 products were expressed at the cell surface up to 72 hours and stimulated the maturation of DCs. In vivo, these DCs prompted efficient peptide-specific T-cell activation and target cell killing which were superior to those induced by peptide-loaded, LPS-stimulated DCs. This superiority was also evident in the ability to protect mice from tumor progression following the administration of B16F10.9 melanoma cells and to inhibit the development of pre-established B16F10.9 tumors. Our results provide evidence that the products of two recombinant genes encoding for peptide-hβ2m-TLR4 and peptide-hβ2m-K(b) expressed from exogenous mRNA can cooperate to couple Major Histocompatibility Complex (MHC-I) peptide presentation to TLR-mediated signaling, offering a safe, economical and highly versatile genetic platform for a novel category of CTL-inducing vaccines.

Dramatic efficacy improvement of a DC-based vaccine against AML by CD25 T cell depletion allowing the induction of a long-lasting T cell response. Cancer Immunol Immunother 2009; 58:1669-77.

Abstract
Dendritic cell (DC)-based vaccination is a promising approach to enhance anti-tumor immunity that could be considered for acute myeloid leukemia (AML) patients with high-risk of relapse. Our purpose was to study the efficiency and to optimize the immunogenicity of a DC-based vaccine in a preclinical AML murine model. In this report, C57BL6 mice were vaccinated with DC pulsed with peptides eluted (EP) from the syngeneic C1498 myelomonocytic leukemic cell line in a prophylactic setting. In this model, a natural antileukemic immunity mediated by NK cells was observed in the control unloaded DC-vaccinated group. On the other hand, we showed that the cytotoxic antileukemic immune response induced by vaccination with eluted peptides pulsed-DC (DC/EP), in vitro and in vivo, was mainly mediated by CD4(+) T cells. Treatment with anti-CD25 antibody to deplete CD4(+) CD25(+) regulatory T cells before DC-vaccination dramatically improved the antileukemic immune response induced by immunization, and allowed the development of long-lasting immune responses that were tumor protective after a re-challenge with leukemic cells. Our results suggest that this approach could be successful against weakly immunogenic tumors such as AML, and could be translated in human.
