Viral vectors may address both of these issues, as they can be used to deliver intact tumor Ags to DCs, and have been shown to inhibit the suppression mediated by CD4+CD25+ regulatory T cells.

VRP infection of immature DCs was superior to TNF-alpha treatment at inducing phenotypic maturation of DCs, and was comparable to LPS stimulation.

|
Additionally, VRP-infected DC cultures secreted substantial amounts of the proinflammatory cytokines IL-6, TNF-alpha, and IFN-alpha.

|
Finally, DCs transduced with a VRP encoding the influenza matrix protein (FMP) stimulated 50% greater expansion of FMP-specific CD8+ CTL when compared with TNF-alpha-matured DCs pulsed with an HLA-A*0201-restricted FMP peptide.

DNA, VRP and Ad5 vaccines all primed monkeys for strong immune responses after the Pox boost.

We also evaluated the effect of co-expressing granulocyte macrophage colony-stimulating factor (GM-CSF) in the vaccine context.

IFN-α/β-inducing and GM-CSF-expressing CSF-VRP were similar to unmodified VRP in terms of antibody and peripheral T-cell responses, and in reducing the blood levels of challenge virus RNA.

Animals vaccinated with VRPs expressing EBNA-3A and EBNA-3B developed LCV-specific CD4 and CD8 T cell immunity to these proteins, while VRPs expressing gp350 did not induce detectable T cell immunity to gp350.

We have shown that a vaccine based on alphavirus replicon particles (VRP) activates strong cellular and humoral immunity to tyrosinase-related protein-2 (TRP2) melanoma antigen, providing prophylactic and therapeutic effects in stringent mouse models.

|
Here, we report that the immunogenicity and efficacy of this vaccine is increased in combination with either antagonist anti-CTL antigen-4 (CTLA-4) or agonist anti-glucocorticoid-induced TNF family-related gene (GITR) immunomodulatory monoclonal antibodies (mAb).

|
These mAbs had similar adjuvant effects in priming an adaptive immune response against the vaccine-encoded antigen, augmenting, respectively, approximately 4- and 2-fold the TRP2-specific CD8(+) T-cell response and circulating Abs, compared with the vaccine alone.

|
Furthermore, while both mAbs increased the frequency of tumor-infiltrating CD8(+) T cells, anti-CTLA-4 mAb also increased the quantity of intratumor CD4(+)Foxp3(-) T cells expressing the negative costimulatory molecule programmed death-1 (PD-1).

They also indicate that tumor-infiltrating CD4(+)Foxp3(-)PD-1(+) T cells may affect the outcome of immunomodulatory treatments.
