sigma-aldrich, mo,usa) staining solution. the reaction was stopped after 46 min by placing the plate under tap water.the spots were counted using an elispot reader (cellular technology ltd., shaker heights, oh, usa).for rah-specific t cell staining, spleens were harvested seven days after the immunizations, andrah-specific cd8+ t cells were detected by tetramer staining using a pe-labeled rah tetramer(beckman coulter, ca, usa) and a fitc-labeled anti-cd8 monoclonal antibody (mab) (ebioscience,ca, usa). the stained rah-specific cd8+ t cells were analyzed by flow cytometry.supplementary information accompanies this paper at /srepcompeting financial interests: the authors declare no competing financial interests.how to cite this article: song, y.-c. and liu, s.-j. a tlr9 agonist enhances the anti-tumor immunityof peptide and lipopeptide vaccines via different mechanisms. sci. rep. 5, 12578;

(2) manifest an improved fusion efficacy;(3) produce elevated levels of il-12; (4) simultaneously activatecd4+ and cd8+ t cells, which secrete high levels of interferon (ifn); (5) potently induce antigen-specific ctl activity;and (6) manifest a superior efficacy in inhibiting the generationof cd4+cd25+foxp3+ tregs.20 nonetheless, when dc/cancercell fusions are generated with neoplastic cells producing extremelyhigh levels of tgf1, they inhibit the activity of ctls in vitro.therefore, incorporating the simultaneous activation of multipletlrs and the blockade of immunosuppressive that are intrinsicallyproduced by dc/neoplastic cell fusions may significantly enhancethe therapeutic potential of this approach.improving the immunogenicity of malignant cellsmost, if not all, malignant cells secrete multipleimmunosuppressive mediators such as tgfmolecules normally inhibit the initiation of efficient ctlresponses,21 the microenvironment of malignant cells used forthe generation of dc/cancer cell fusions immunostimulatory. several strategies to inhibit the production ofimmunosuppressive factors by cancer cells have been developed,including the administration of neutralizing antibodies22 and smallchemical inhibitors,23 as well as the transfection of specific smallinterferingrnas (sirnas)24 or constructs coding for a solublevariant of the tgf receptor.25 also heat-shock proteins (hsps),which have recently been implicated in the immunogenicity ofapoptotic and necrotic cells, might constitute effective adjuvantfor boosting the efficacy of dc/neoplastic cell fusions.26,27 hspsgenerally operate as chaperons for a wide panel of peptides,including antigenic peptides, and hsp/peptide complexes notonly can be efficiently taken up by dcs through specific receptors,but also can be presented in molecules the dc surface.28 we have previously reported thattlr2-stimulated dcs fused with heat-treated cancer cells areimmunogenic, as demonstrated by: (1) the upregulation of multiplehsps, mhc class i and ii molecules, taas, cd80, cd86, cd83,and il-12; (2) their ability producing high levels of ifn; and (3) the capacity to efficientlyelicited antigen-specific ctl activity.26 more recently, we havedemonstrated that the secretion of tgf1, il-10 and vegrfrom whole cancer cells is significantly limited upon exposure topharmaceutical grade ethanol, a maneuver that does not reduce theevels of mhc class i molecules and taas on the cell surface.27moreover, ethanol, employed at concentrations that affect tumorgrowth, promoted the upregulation of hsps. hsps exposed bycancer cells can be recognized by dcs via tlr4, facilitating theiractivation and promoting antigen processing and presentation.29of note, malignant cells that undergo immunogenic apoptosisectopically expose the ca2+-binding chaperone calreticulin (crt)on the cell surface, allowing taas
