In this report, we evaluated the potential of RNA interference (RNAi)-mediated silencing of Foxo3 in antigen-presenting cells as an adjuvant for HER2/neu DNA cancer vaccines.

|
Bicistronic plasmids expressing the N-terminal extracellular domain of human HER-2/neu and the Foxo3 short hairpin RNA (hN'-neu-Foxo3 shRNA) or the scrambled control (hN'-neu-scramble shRNA) were subcutaneously injected into mice by gene gun administration to elicit antitumor immunity against p185neu-overexpressing MBT-2 bladder tumor cells.
|

21107437
|
We found that mice treated with hN'-neu-Foxo3 shRNA showed greater reductions in tumor growth and longer survival times than mice treated with hN'-neu-scramble shRNA, indicating that the silencing of Foxo3 enhanced the antitumor efficacy of the HER-2/neu cancer vaccine.
|

21107437
|
Cytotoxicity analyses further revealed that the Foxo3 shRNA-enhanced antitumor effect was associated with significant increases in the number of functional CD8(+) T cells and in the levels of cytotoxic T lymphocytes activity.
|
5 |
21107437
|
Finally, Foxo3 suppression was shown to markedly improve the effect of the HER-2/neu DNA vaccine in limiting the growth and lung metastases of MBT-2 cells.
|

21107437
|
Overall, these results support RNAi-mediated silencing of Foxo3 as an effective strategy to enhance the therapeutic antitumor effect of HER-2/neu DNA vaccines against p185neu-positive tumors.

The lower survival levels observed in memory B cells from ST subjects were the result of disrupted IL-2 signaling that led to increased transcriptional activity of Foxo3a and increased expression of its proapoptotic target TRAIL.
|

|
Our results thus establish a direct role for Foxo3a/TRAIL signaling in the persistence of memory B cells and provide a mechanism for the reduced survival of memory B cells during HIV infection.

Finally, real-time quantitative PCR (qRT-PCR) analysis of the expression profile of BCG-infected macrophages showed an upregulation of two pro-apoptotic targets of FOXO3, NOXA and p53 upregulated modulator of apoptosis (PUMA).

FoxO3 is a negative regulator of primary CD8+ T-cell expansion but not of memory formation.

|
Since the role of FoxO3 has been poorly studied in the immune system, here we have evaluated its involvement in the CD8(+) T-cell response.
|
47 |
25245112
|
We observe that CD8(+) T cells deficient for FoxO3 undergo a significantly greater primary expansion than their wild-type (WT) counterparts in response to both infectious (vaccinia virus) or non-infectious (non-replicating cellular vaccine) immunogens, resulting in a larger cohort of cells following contraction.
|
48 |

|
Taken together, our data show that FoxO3 is a negative regulator of the CD8(+) T-cell response, specifically during the primary expansion.
