Abstract
Low response rates and immune-related adverse events limit the remarkable impact of cancer immunotherapy. To improve clinical outcomes, preclinical studies have shown that combining immunotherapies with N-terminal Hsp90 inhibitors resulted in improved efficacy, even though induction of an extensive heat shock response (HSR) and less than optimal dosing of these inhibitors limited their clinical efficacy as monotherapies. We discovered that the natural product Enniatin A (EnnA) targets Hsp90 and destabilizes its client oncoproteins without inducing an HSR. EnnA triggers immunogenic cell death in triple-negative breast cancer (TNBC) syngeneic mouse models and exhibits superior antitumor activity compared to Hsp90 N-terminal inhibitors. EnnA reprograms the tumor microenvironment (TME) to promote CD8+ T cell-dependent antitumor immunity by reducing PD-L1 levels and activating the chemokine receptor CX3CR1 pathway. These findings provide strong evidence for transforming the immunosuppressive TME into a more tumor-hostile milieu by engaging Hsp90 with therapeutic agents involving novel mechanisms of action.

Abstract
Cancer immunotherapy often depends on recognition of peptide epitopes by cytotoxic T lymphocytes (CTLs). The tumor microenvironment (TME) is enriched for peroxynitrite (PNT), a potent oxidant produced by infiltrating myeloid cells and some tumor cells. We demonstrate that PNT alters the profile of MHC class I bound peptides presented on tumor cells. Only CTLs specific for PNT-resistant peptides have a strong antitumor effect in vivo, whereas CTLs specific for PNT-sensitive peptides are not effective. Therapeutic targeting of PNT in mice reduces resistance of tumor cells to CTLs. Melanoma patients with low PNT activity in their tumors demonstrate a better clinical response to immunotherapy than patients with high PNT activity. Our data suggest that intratumoral PNT activity should be considered for the design of neoantigen-based therapy and also may be an important immunotherapeutic target.

Abstract
Recent studies have revealed that tumor cells decrease their immunogenicity by epigenetically repressing the expression of highly immunogenic antigens to survive in immunocompetent hosts. We hypothesized that these epigenetically hidden “stealth” antigens should be favorable targets for cancer immunotherapy due to their high immunogenicity. To identify these stealth antigens, we treated human lung cell line A549 with DNA methyltransferase inhibitor 5‐aza‐2′‐deoxycytidine (5Aza) and its prodrug guadecitabine for 3 d in vitro and screened it using cDNA microarray analysis. We found that the gene encoding sperm equatorial segment protein 1 (SPESP1) was re‐expressed in cell lines including solid tumors and leukemias treated with 5Aza, although SPESP1 was not detected in untreated tumor cell lines. Using normal human tissue cDNA panels, we demonstrated that SPESP1 was not detected in normal human tissue except for testis and placenta. Moreover, we found using immunohistochemistry SPESP1 re‐expression in xenografts in BALB/c‐nu/nu mice that received 5Aza treatment. To assess the antigenicity of SPESP1, we stimulated human CD4+ T‐cells with a SPESP1‐derived peptide designed using a computer algorithm. After repetitive stimulation, SPESP1‐specific helper T‐cells were obtained; these cells produced interferon‐γ against HLA‐matched tumor cell lines treated with 5Aza. We also detected SPESP1 expression in freshly collected tumor cells derived from patients with acute myeloid leukemia or lung cancer. In conclusion, SPESP1 can be classified as a stealth antigen, a molecule encoded by a gene that is epigenetically silenced in tumor cells but serves as a highly immunogenic antigen suitable for cancer immunotherapy.

Abstract
Identification of immunogenic tumor antigens, their corresponding T cell epitopes and the selection of effective adjuvants are prerequisites for developing effective cancer immunotherapies such as therapeutic vaccines. Murine double minute 2 (MDM2) is an E3 ubiquitin-protein ligase that negatively regulates tumor suppressor p53. Because MDM2 overexpression serves as a poor prognosis factor in various types of tumors, it would be beneficial to develop MDM2-targeted cancer vaccines. In this report, we identified an MDM2-derived peptide epitope (MDM232-46) that elicited antigen-specific and tumor-reactive CD4+ T cell responses. These CD4+ T cells directly killed tumor cells via granzyme B. MDM2 is expressed in head and neck cancer patients with poor prognosis, and the T cells that recognize this MDM2 peptide were present in these patients. Notably, Nutlin-3 (MDM2-p53 blocker), inhibited tumor cell proliferation, was shown to augment antitumor T cell responses by increasing MDM2 expression, HLA-class I and HLA-DR through class II transactivator (CIITA). These results suggest that the use of this MDM2 peptide as a therapeutic vaccine combined with MDM2 inhibitors could represent an effective immunologic strategy to treat cancer.

Abstract
Abstract
Background: Recent advances in immunotherapy have revolutionized cancer treatment. Immune checkpoint blockade and adoptive T cell therapy can induce durable responses in some patients. However, the majority of patients fail to respond. Absence of T cell infiltration to the tumor site in solid tumors is considered as one of the major obstacles for effective immunotherapy. Thus, strategies to enhance T cell trafficking and infiltration into the tumor parenchyma is a major research need.
Methods: Using a combination of in vivo mouse tumor models and in vitro assays we compared the capacity of various formulations and routes of administration of poly-IC (a dsRNA mimic that functions as a pattern recognition receptor ligand) in enhancing T cell tumor infiltration and generating antitumor responses.
Results: Our results showed that poly-ICLC (poly-IC containing poly-lysine and carboxymethylcellulose) enhanced CD8 T cell infiltration into the tumors resulting in the control of tumor growth. These effects relied both on the route of administration as well as on the formulation of poly-IC. Systemic administration (i.v. or i.m.) of poly-ICLC was significantly more effective in inducing CD8 T cell tumor infiltration as compared to intra-tumoral injections. Also, the effects poly-ICLC were substantially more pronounced as compared to unmodified poly-IC. The antitumor effect of poly-ICLC was mediated via MDA-5 and IFN-I, whereas TLR3 stimulation was not required. Interestingly, poly-ICLC stimulated IFN-I responses on tumor vascular endothelial cells (VECs) enhancing the expression of adhesion molecules (VCAM-I), production of IFN-I and T cell recruiting chemokines (CXCL9/CXCL10). Using conditional knockout mice, showed that ablation of IFNab receptors in VECs impaired the antitumor effects of poly-ICLC. IFN-I production upon MDA5 stimulation is required to enhance the secretion of (CXCL9/CXCL10) by VECs indicating that this IFN-I/CXCL9/CXCL10 regulatory axis is crucial for recruiting effector T cells into the tumor parenchyma. The T cell infiltrating effects of poly-ICLC were mainly observed in tumors and not in normal tissues.
Conclusions: Systemic administration of poly-ICLC improves T cell infiltration to solid tumors in an MDA5/IFN-I dependent manner. These findings should have a strong impact on improving T cell-based treatments for solid cancers such as adoptive T cell therapy and antitumor vaccines.

Abstract
Relatively simple, synthetic, double-stranded RNAs can be powerful viral pathogen-associated molecular pattern (PAMP) mimics, inducing a panoply of antiviral and antitumor responses that act at multiple stages of host defense. Their mechanisms of action and uses are beginning to be understood, alone, in combination with other therapeutics, or as novel PAMP-adjuvants providing the critical danger signal that has been missing from most cancer and other modern vaccines. Dose, timing, route of administration combinations, and other clinical variables can have a critical impact on immunogenicity. This article reviews advances in the use of polyinosinic-polycytidylic acid and derivatives, in particular poly-ICLC.

Abstract
Placenta-specific 1 (PLAC1) is expressed primarily in placental trophoblasts but not in normal tissues and is a targetable candidate for cancer immunotherapy because it is a cancer testis antigen known to be up-regulated in various tumors. Although peptide epitopes capable of stimulating CD8 T cells have been previously described, there have been no reports of PLAC1 CD4 helper T lymphocyte (HTL) epitopes and the expression of this antigen in head and neck squamous cell carcinoma (HNSCC). Here, we show that PLAC1 is highly expressed in 74.5% of oropharyngeal and 51.9% of oral cavity tumors from HNSCC patients and in several HNSCC established cell lines. We also identified an HTL peptide epitope (PLAC131-50) capable of eliciting effective antigen-specific and tumor-reactive T cell responses. Notably, this peptide behaves as a promiscuous epitope capable of stimulating T cells in the context of more than one human leukocyte antigen (HLA)-DR allele and induces PLAC1-specific CD4 T cells that kill PLAC1-positive HNSCC cell lines in an HLA-DR-restricted manner. Furthermore, T-cells reactive to PLAC131-50 peptide were detected in the peripheral blood of HNSCC patients. These findings suggest that PLAC1 represents a potential target antigen for HTL based immunotherapy in HNSCC.

Abstract
Immunotherapies have become the first line of treatment for many cancer types. Unfortunately, only a small fraction of patients benefits from these therapies. This low rate of success can be attributed to 3 main barriers: 1) low frequency of anti-tumor specific T cells; 2) lack of infiltration of the anti-tumor specific T cells into the tumor parenchyma and 3) accumulation of highly suppressive cells in the tumor mass that inhibit the effector function of the anti-tumor specific T cells. Thus, the identification of immunomodulators that can increase the frequency and/or the infiltration of antitumor specific T cells while reducing the suppressive capacity of the tumor microenvironment is necessary to ensure the effectiveness of T cell immunotherapies. In this review, we discuss the potential of poly-ICLC as a multi-functional immune modulator for treating cancer and its impact on the 3 above mentioned barriers. We describe the unique capacity of poly-ICLC in stimulating 2 separate pattern recognition receptors, TLR3 and cytosolic MDA5 and the consequences of these activations on cytokines and chemokines production. We emphasize the role of poly-ICLC as an adjuvant in the setting of peptide-based cancer vaccines and in situ tumor vaccination by mimicking natural immune responses to infections. Finally, we summarize the impact of poly-ICLC in enhancing T infiltration into the tumor parenchyma and address the implication of this finding in the clinic.

Abstract
BACKGROUND Immunotherapies, such as immune checkpoint inhibitors and adoptive cell therapies, have revolutionized cancer treatment and resulted in complete and durable responses in some patients. Unfortunately, most immunotherapy treated patients still fail to respond. Absence of T cell infiltration to the tumor site is one of the major obstacles limiting immunotherapy efficacy against solid tumors. Thus, the development of strategies that enhance T cell infiltration and broaden the antitumor efficacy of immunotherapies is greatly needed. METHODS We used mouse tumor models, genetically deficient mice and vascular endothelial cells (VECs) to study the requirements for T cell infiltration into tumors. RESULTS A specific formulation of poly-IC, containing poly-lysine and carboxymethylcellulose (PICLC) facilitated the traffic and infiltration of effector CD8 T cells into the tumors that reduced tumor growth. Surprisingly, intratumoral injection of PICLC was significantly less effective in inducing tumor T cell infiltration and controlling growth of tumors as compared with systemic (intravenous or intramuscular) administration. Systemically administered PICLC, but not poly-IC stimulated tumor VECs via the double-stranded RNA cytoplasmic sensor MDA5, resulting in enhanced adhesion molecule expression and the production of type I interferon (IFN-I) and T cell recruiting chemokines. Expression of IFNαβ receptor in VECs was necessary to obtain the antitumor effects by PICLC and IFN-I was found to directly stimulate the secretion of T cell recruiting chemokines by VECs indicating that this cytokine-chemokine regulatory axis is crucial for recruiting effector T cells into the tumor parenchyma. Unexpectedly, these effects of PICLC were mostly observed in tumors and not in normal tissues. CONCLUSIONS These findings have strong implications for the improvement of all types of T cell-based immunotherapies for solid cancers. We predict that systemic administration of PICLC will improve immune checkpoint inhibitor therapy, adoptive cell therapies and therapeutic cancer vaccines.

Abstract
Dendritic cells are an important link between innate and adaptive immune response. The role of dendritic cells in bone homeostasis, however, is not understood. Osteoporosis medications that inhibit osteoclasts have been associated with osteonecrosis, a condition limited to the jawbone, thus called medication-related osteonecrosis of the jaw. We propose that disruption of the local immune response renders the oral microenvironment conducive to osteonecrosis. We tested whether zoledronate (Zol) treatment impaired dendritic cell (DC) functions and increased bacterial load in alveolar bone in vivo and whether DC inhibition alone predisposed the animals to osteonecrosis. We also analyzed the role of Zol in impairment of differentiation and function of migratory and tissue-resident DCs, promoting disruption of T-cell activation in vitro. Results demonstrated a Zol induced impairment in DC functions and an increased bacterial load in the oral cavity. DC-deficient mice were predisposed to osteonecrosis following dental extraction. Zol treatment of DCs in vitro caused an impairment in immune functions including differentiation, maturation, migration, antigen presentation, and T-cell activation. We conclude that the mechanism of Zol-induced osteonecrosis of the jaw involves disruption of DC immune functions required to clear bacterial infection and activate T cell effector response.

Abstract
Abstract
Peptide vaccines can be a successful and cost-effective way of generating T-cell responses against defined tumor antigens, especially when combined with immune adjuvants such as poly-IC. However, strong immune adjuvants can induce a collateral increase in numbers of irrelevant, nonspecific T cells, which limits the effectiveness of the peptide vaccines. Here, we report that providing prolonged IL2 signaling in the form of either IL2/ anti-IL2 complexes or pegylated IL2 overcomes the competitive suppressive effect of irrelevant T cells, allowing the preferential expansion of antigen-specific T cells, and increasing the therapeutic effectiveness of the vaccines against established tumors. This vaccination strategy using peptides and sustained IL2 could be taken into the clinic for the treatment of cancer.

Abstract
Abstract
Although clinically apparent metastasis is associated with late stages of cancer development, micro-metastatic dissemination may be an early event. However, the fate of these early disseminated tumor cells (DTC) remains elusive.
Using the syngeneic mouse models, we demonstrated that although both orthotopically-implanted murine 4T1 and EMT6 tumors are capable of disseminating into secondary organs, only 4T1 tumors develop overt metastasis. However, EMT6 tumors induce an anti-tumor immunity in syngeneic mice and that eradicates disseminated tumor cells (DTC) in distant organs. Following the complete removal of primary EMT6 tumors, mice do not develop detectable metastasis and generate an immunological memory that leads to complete elimination of repeatedly injected tumor cells via tail vein. Conversely, these cells readily grow and metastasize in immuno-deficient athymic or Rag2- mice, and when g-MDSCs from 4T1 tumor-bearing mice were co-injected into immunocompetent EMT6 primed mice. In contrast to complete resection, mice with residual tumors following surgery exhibited an enhanced growth of local and concomitant growth of DTCs at metastatic site with increased g-MDSCs accumulation in lung and spleen.
Together, our results suggest that some tumors are capable of inducing anti-tumor immunity against the DTCs when complete resection of primary tumor cures animals. However, in the presence of residual tumors, inflammation induced by surgical procedure promote the growth of DTCs.

Abstract
Abstract
Despite breakthroughs in immune checkpoint inhibitor (ICI) immunotherapy, not all human cancers respond to ICI immunotherapy and only fraction of patients with responsive tumors have a durable response to current ICI immunotherapy. This clinical conundrum suggests that additional immune checkpoints may exist, particularly in cancers resistant to current ICI immunotherapy, such as colorectal cancer. We report here that interferon regulatory factor 8 (IRF8) deficiency led to impairment of cytotoxic T lymphocyte (CTL) activation in a peptide vaccine model and allowed allograft transplant tumor tolerance. These effects were associated with upregulation of the CTL surface marker CD44. However, analysis of chimeric mice with competitive reconstitution of wild type and IRF8 KO bone marrow cells as well as mice with IRF8 deficiency only in T cells indicated that IRF8 plays no intrinsic role in CTL activation. Instead, IRF8 functioned as a repressor of osteopontin (OPN), the physiological ligand for CD44 on T cells, in CD11b+Ly6CloLy6G+ myeloid cells and OPN acted as a potent T cell suppressor. In vitro stimulation of CTLs in the presence of OPN resulted in decreased expression of activation markers CD69 and CD25 and inhibited proliferation and interferon gamma (IFNg) secretion. Expression of OPN was found to be upregulated in both myeloid cells and colon epithelial cells following silencing of IRF8 expression. IRF8 bound to the Spp1 promoter, which encodes OPN, to repress OPN expression in colon epithelial cells. Correspondingly, human colon carcinoma cells exhibited decreased IRF8 and increased OPN expression. These increased OPN levels inhibited human PBMC proliferation and IFNg secretion. The elevated expression of OPN in human colon carcinoma was correlated with decreased patient survival. Our data indicates that myeloid and tumor cell-expressed OPN acts as a novel immune checkpoint to suppress T cell activation and confer host tumor immune tolerance. Blockade of this checkpoint may expand the pool of patients who may benefit from ICI immunotherapy.

Abstract
Abstract
Large cohorts of recent clinical studies have firmly established that increased levels of tumor-infiltrating lymphocytes (TILs) in TNBC and HER2+ subtypes predicted better clinical outcome compared to the luminal subtype. These observations led to the hypothesis that women with TNBC or HER2+ subtypes may respond to a checkpoint blockade. However, early results from these trials using check point inhibitors alone or in combination with chemotherapy have shown very little promise in breast cancer patients, despite the remarkable long-lasting responses in other hard to treat malignancies such as non-small cell lung and melanoma. Although the outcome falls short of the expectation, it has suggested that the combinations of check point blockade with therapeutics that target immunosuppression may potentiate its efficacy. TNFα exhibits paradoxical roles; it may fuel tumor cell growth, invasion and metastasis in some tumor types, while in others it induces cytotoxic cell death. We recently demonstrated that TNFα distinctly induces A20 in TNBC subtype and protects these cells from TNFα-induced cytotoxic cell death by upregulating HSP70 protein and maintaining EMT/CSC phenotype. In contrast, luminal MCF7 or ZR75-1 cells display approximately 70% apoptosis when treated with TNFα. Overexpression of A20 in luminal cells not only protected them from TNFα-induced cytotoxicity by upregulating HSP70 and EMT/CSC phenotype, but also exhibited aggressive metastatic properties in mouse xenograft models. Furthermore, we show that A20/HSP70 pathway attracts tumor-infiltrating lymphocytes (TILs) while inducing the accumulation of immunosuppressive MDSCs in syngeneic mouse models. Interestingly, pulmonary DTCs as well as the immune infiltrates from 4T1 tumor-bearing mice exhibited significantly higher HSP70 expression. Therefore, we proposed that targeting HSP70 may potentiate the efficacy of immunotherapy in preclinical models of breast cancer. As previously reported, murine 4T1 tumors do respond to check point inhibitors. We reasoned that this may be an appropriate model to test the efficacy of HSP70 inhibitor, JG-231. Expectedly, there was no difference in tumor growth and metastasis between control and anti-PDL1 treated animals, however, combination of anti-PDL1 antibody ed with JG-231 and chemotherapy (cyclophosphamide-CTX) significantly reduced primary tumor growth (>10 fold) and eliminated metastasis. Collectively, our pilot experiments provide a strong rationale for testing our hypothesis and may lead to a rapid translation into the clinical utility.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) originates from squamous epithelium of the upper aerodigestive tract and is the most common malignancy in the head and neck region. Among HNSCCs, oropharynx squamous cell carcinoma (OSCC) has a unique profile and is associated with human papillomavirus infection. Recently, anti-programmed cell death-1 monoclonal antibody has yielded good clinical responses in recurrent and/or metastatic HNSCC patients. Therefore, programmed death-ligand 1 (PD-L1) may be a favorable target molecule for cancer immunotherapy. Although PD-L1-expressing malignant cells could be targeted by PD-L1-specific CD8+ cytotoxic T lymphocytes, it remains unclear whether CD4+ helper T lymphocytes (HTLs) recognize and kill tumor cells in a PD-L1-specific manner. METHODS The expression levels of PD-L1 and HLA-DR were evaluated using immunohistochemical analyses. MHC class II-binding peptides for PD-L1 were designed based on computer algorithm analyses and added into in vitro culture of HTLs with antigen-presenting cells to evaluate their stimulatory activity. RESULTS We found that seven of 24 cases of OSCC showed positive for both PD-L1 and HLA-DR and that PD-L1241-265 peptide efficiently activates HTLs, which showed not only cytokine production but also cytotoxicity against tumor cells in a PD-L1-dependent manner. Also, an adoptive transfer of the PD-L1-specific HTLs significantly inhibited growth of PD-L1-expressing human tumor cell lines in an immunodeficient mouse model. Importantly, T cell responses specific for the PD-L1241-265 peptide were detected in the HNSCC patients. CONCLUSIONS The cancer immunotherapy targeting PD-L1 as a helper T-cell antigen would be a rational strategy for HNSCC patients.

Abstract
Abstract
While current immune checkpoint inhibitors (ICIs) have shown efficacy in a wide variety of human cancers, many patients and cancer types fail to respond to ICI immunotherapy, suggesting the presence of other immunoinhibitory checkpoints. We report here that a deficiency in the transcription factor interferon regulatory factor 8 (IRF8) led to a loss of function of cytotoxic T lymphocytes (CTLs) in both an allograft tumor and a peptide vaccine model. However, a T cell-specific knockout and a mixed chimera model demonstrated that IRF8 suppressed CTL activation through a CTL-extrinsic mechanism. This was found to be through IRF8-dependent suppression of the matricellular protein osteopontin (OPN). During colorectal cancer (CRC) development, IRF8 is downregulated in both tumor-associated CD11b+Ly6CloLy6Ghi myeloid cells and colon epithelial cells, where it represses OPN expression by binding to its promoter. Accordingly, in both mouse CRC models and human CRC patients, transcriptional downregulation of IRF8 was accompanied by an upregulation of OPN at the transcriptional and protein level. Enhanced levels of OPN were found to negatively correlate with patient survival. In vitro stimulation of mouse and human CTLs in the presence of OPN led to decreased activation and interferon gamma secretion. Similarly, deletion of spp1, which encodes for OPN, from murine CT26 colon adenocarcinoma cells caused increased susceptibility to CTL-mediated lysis and enhanced CTL activation. As such, tumor and myeloid-derived OPN may function as a novel immune checkpoint to restrain host CTL activation.

Abstract
Although clinically apparent metastasis is associated with late stages of cancer development, micro-metastatic dissemination may be an early event. However, the fate of these early disseminated tumor cells (DTC) remains elusive. We show that despite their capacity to disseminate into secondary organs, 4T1 tumor models develop overt metastasis while EMT6-tumor bearing mice clear DTCs shed from primary tumors as well as those introduced by intravenous (IV) injection. Following the surgical resection of primary EMT6 tumors, mice do not develop detectable metastasis and reject IV-injected tumor cells. In contrast, these cells readily grow and metastasize in immuno-deficient athymic or Rag2−/− mice, an effect mimicked by CD8+ T-cell depletion in immunocompetent mice. Furthermore, recombinant G-CSF or adoptive transfer of granulocytic-MDSCs isolated from 4T1 tumor-bearing mice, induce metastasis by suppressing CD8+ T-cells in EMT6-primed mice. Our studies support the concept of immune surveillance providing molecular insights into the immune mechanisms during tumor progression. Dissemination of tumor cells from the primary site is an early event. Here, the authors show that the early disseminated tumor cells are actively cleared by the host cytotoxic T lymphocytes induced by the primary tumor and that infiltration of granulocytic myeloid-derived suppressor cells counteracts such immune protection and allow metastasis development.

Abstract
Abstract
Hepatocellular carcinoma (HCC) is the major form of liver cancer for which there is no effective therapy. Genetic modification with T-cell receptors (TCR) specific for HCC-associated antigens, such as α-fetoprotein (AFP), can potentially redirect human T-cells to specifically recognize and kill HCC tumor cells to achieve antitumor effects. In this study, by using lentivector and peptide immunization, we identified a population of CD8-T-cells in HLA-A2 transgenic AAD mice that recognized AFP158 epitope on human HCC cells. Adoptive transfer of the AFP158-specific mouse CD8-T-cells eradicated HepG2 tumor xenografts as large as 2cm in diameter in immunocompromised NSG mice. We then established T-cell hybridoma clones from the AFP158-specific mouse CD8-T-cells and identified three sets of paired TCR genes out of 5 hybridomas. Expression of the murine TCR genes redirected primary human T-cells to bind HLA-A2/AFP158 tetramer. The TCR gene-engineered human T-cells (TCR-T) also specifically recognized HLA-A2+AFP+ HepG2 HCC tumor cells and produced effector cytokines. Importantly, the TCR-T-cells could specifically kill HLA-A2+AFP+ HepG2 tumor cells without significant toxicity to normal primary hepatocytes in vitro. Adoptive transfer of the AFP-specific human TCR-T-cells could eradicate HepG2 tumors in NSG mice. Conclusion: We have identified novel AFP-specific murine TCR genes that can redirect human T-cells to specifically recognize and kill HCC tumor cells, and those AFP158-specific TCRs have a great potential to engineer a patient’s autologous T-cells to treat HCC tumors.

Abstract
Despite breakthroughs in immune checkpoint inhibitor (ICI) immunotherapy, not all human cancers respond to ICI immunotherapy and a large fraction of patients with the responsive types of cancers do not respond to current ICI immunotherapy. This clinical conundrum suggests that additional immune checkpoints exist. We report here that interferon regulatory factor 8 (IRF8) deficiency led to impairment of cytotoxic T lymphocyte (CTL) activation and allograft tumor tolerance. However, analysis of chimera mice with competitive reconstitution of WT and IRF8-KO bone marrow cells as well as mice with IRF8 deficiency only in T cells indicated that IRF8 plays no intrinsic role in CTL activation. Instead, IRF8 functioned as a repressor of osteopontin (OPN), the physiological ligand for CD44 on T cells, in CD11b+Ly6CloLy6G+ myeloid cells and OPN acted as a potent T cell suppressor. IRF8 bound to the Spp1 promoter to repress OPN expression in colon epithelial cells, and colon carcinoma exhibited decreased IRF8 and increased OPN expression. The elevated expression of OPN in human colon carcinoma was correlated with decreased patient survival. Our data indicate that myeloid and tumor cell-expressed OPN acts as an immune checkpoint to suppress T cell activation and confer host tumor immune tolerance.

Abstract
UNLABELLED Hepatocellular carcinoma (HCC) is the major form of liver cancer for which there is no effective therapy. Genetic modification with T-cell receptors (TCRs) specific for HCC-associated antigens, such as α-fetoprotein (AFP), can potentially redirect human T cells to specifically recognize and kill HCC tumor cells to achieve antitumor effects. In this study, using lentivector and peptide immunization, we identified a population of cluster of differentiation 8 (CD8) T cells in human leukocyte antigen (HLA)-A2 transgenic AAD mice that recognized AFP158 epitope on human HCC cells. Adoptive transfer of the AFP158 -specific mouse CD8 T cells eradicated HepG2 tumor xenografts as large as 2 cm in diameter in immunocompromised nonobese diabetic severe combined immunodeficient gamma knockout (NSG) mice. We then established T-cell hybridoma clones from the AFP158 -specific mouse CD8 T cells and identified three sets of paired TCR genes out of five hybridomas. Expression of the murine TCR genes redirected primary human T cells to bind HLA-A2/AFP158 tetramer.

Abstract
The human T cell receptor is capable of distinguishing between normal and post-translationally modified peptides. Because aberrant phosphorylation of cellular proteins is a hallmark of malignant transformation, the expression of the phosphorylated epitope could be an ideal antigen to combat cancer without damaging normal tissues. p53 activates transcription factors to suppress tumors by upregulating growth arrest and apoptosis-related genes. In response to DNA damage, p53 is phosphorylated at multiple sites including Ser33 and Ser37. Here, we identified phosphorylated peptide epitopes from p53 that could elicit effective T helper responses. These epitope peptides, p5322-41/Phospho-S33 and p5322-41/Phospho-S37, induced T helper responses against tumor cells expressing the phosphorylated p53 protein. Moreover, chemotherapeutic agents augmented the responses of such CD4 T cells via upregulation of phosphorylated p53. The upregulation of phosphorylated p53 expression by chemotherapy was confirmed in in vitro and xenograft models. We evaluated phosphorylated p53 expression in the clinical samples of oropharyngeal squamous cell carcinoma and revealed that 13/24 cases (54%) were positive for phosphorylated p53. Importantly, the lymphocytes specific for the phosphorylated p53 peptide epitopes were observed in the head and neck squamous cell cancer (HNSCC) patients. These results reveal that a combination of phosphorylated p53 peptides and chemotherapy could be a novel immunologic approach to treat HNSCC patients.

Abstract
PD-1 is a co-repressive receptor that curbs T cell activation and thereby serves as a protection mechanism against autoimmunity under physiological conditions. Under pathological conditions, tumor cells express PD-L1 as an adaptive resistant mechanism to suppress PD-1+ T cells to evade host immunosurveillance. PD-1 therefore is a key target in cancer immunotherapy. Despite the extensive studies of PD-1 expression regulation, the pdcd1 transcription machinery and regulatory mechanisms are still not fully understood. We report here that the NF-κB p50 homodimer is a transcription regulator of PD-1 in activated T cells. A putative κB sequence exists at the pdcd1 promoter. All five NF-κB Rel subunits are activated in activated T cells. However, only the p50 homodimer directly binds to the κB sequence at the pccd1 promoter in CD4+ and CD8+ T cells. Deficiency in p50 results in reduced PD-1 expression in both CD4+ and CD8+ T cells in vitro. Using an in vivo mixed bone marrow chimera mouse model, we show that p50 regulates PD-1 expression in a cell-intrinsic way and p50 deficiency leads to decreased PD-1 expression in both antigen-specific CD4+ and CD8+ T cells in vivo. The expression levels of H3K4me3-specific histone methyltransferase increased significantly, resulting in a significant increase in H3K4me3 deposition at the pdcd1 promoter in activated CD4+ and CD8+ T cells. Inhibition of H3K4me3 significantly decreased p50 binding to the pdcd1 promoter and PD-1 expression in a T cell line. Our findings determine that the p50-H3K4me3 axis regulates pdcd1 transcription activation in activated T cells.

Abstract
Abstract
Substantial evidence indicates that immunotherapy is a feasible and effective approach for the treatment of numerous types of cancer. Among various immunotherapy options, peptide vaccines to generate antitumor T cells appear as promising candidates, because of their cost effectiveness and ease of implementation. Nevertheless, most peptide vaccines are notorious for being weekly immunogenic and, thus, optimization of the vaccination strategy is essential to achieve therapeutic effectiveness. In addition, effective peptide vaccines must stimulate both CD8 cytotoxic and CD4 helper T lymphocytes. Our group has been successful in designing effective peptide vaccination strategies for inducing CD8 T-cell responses in mouse tumor models. Here, we describe a somewhat similar, but distinct, peptide vaccination strategy capable of generating vast CD4 T-cell responses by combining synthetic peptides with toll-like receptor (TLR) agonists and OX40/CD40 costimulation. This vaccination strategy was efficient in overcoming immune tolerance to a self-tumor- associated antigen and generated significant antitumor effects in a mouse model of malignant melanoma. The optimized peptide vaccine also allowed the expansion of adoptively transferred CD4 T cells without the need for lymphodepletion and IL-2 administration, generating effective antimelanoma responses through the enhancement of proliferative and antiapoptotic activities of CD4 T cells. These results have practical implications in the design of more effective T-cell-based immunotherapies.

Abstract
Abstract
Interferon Regulatory Factor 8 (IRF8, or ICSBP1) is a member of the Interferon Regulatory transcription factor family, and functions as a key hematopoietic transcription factor. Loss of IRF8 leads to defective antigen-presenting cell activity, perturbations in B cell development and, in mouse models, an accumulation of CD11b+Gr1+ immature myeloid cells. However, the role of IRF8 in T cell development and antitumor activity remains unclear. Whole body and chimeric IRF8-knockout mice (IRF8-KO) demonstrate increased susceptibility to both allogenic transplant and carcinogen-induced tumor models. T cell function is crucial for the immune system's endogenous antitumor response. Analysis of the T cell compartment of IRF8-KO mice demonstrated a deficiency in both naïve T cell percentages and total number. Despite this peripheral decrease in T cell numbers, early T cell progenitors in both the bone marrow and thymus were significantly increased in IRF8-KO mice compared to wild-type. To further investigate the role of IRF8 in T cell development and survival, IRF8-KO:WT mixed chimera mice were generated by lethal irradiation of CD45.1+CD45.2+ recipient mice, followed by transfer of CD45.2+ IRF8-KO and CD45.1+ WT bone marrow (BM). Surprisingly, analysis of blood obtained from reconstituted mice demonstrated preferential engraftment and survival of T cells derived from WT, rather than IRF8-KO BM. This imbalanced phenotype was not rescued by increasing the proportion of IRF8-KO BM administered to mice, suggesting the effect was not due to failure of IRF8-KO BM engraftment. Furthermore, analysis of T cell populations in both primary (thymus) and secondary (spleen) lymphoid organs showed a progressive loss of IRF8-KO T cells during their maturation and development process, while WT T cells remained unaltered. Given that IRF8 has been shown in tumor cells to regulate a variety of pro- and anti-apoptotic molecules, we hypothesized that IRF8 controls the peripheral survival of T cells. To test this hypothesis, resting T cells were isolated from the spleen of mixed chimera mice and viability was measured by Annexin V/PI staining. Resting IRF8-KO cells, but not WT, demonstrated a pro-apoptotic phenotype, as shown by increased Annexin V staining. Accordingly, upon in vitro stimulation and activation, IRF8-KO T cells demonstrated increased apoptosis. Our data determine that IRF8 controls both T cell development and peripheral survival, and that loss of IRF8 impairs the T cell antitumor immune response.

Abstract
Abstract
Hepatocellular carcinoma (HCC) is the major form of liver cancer for which there is no effective therapy. Genetic modification with T cell receptors (TCR) specific for HCC-associated antigens, such as α-fetoprotein (AFP), can potentially redirect human T cells to specifically recognize and kill HCC tumor cells to achieve antitumor effects. In this study, by using lentivector and peptide immunization, we identified a population of CD8-T cells in HLA-A2 transgenic AAD mice that recognized AFP158 epitope on human HCC cells. Adoptive transfer of the AFP158-specific CD8-T cells from immunized AAD mice eradicated HepG2 tumor xenografts as large as 2cm in diameter in immunocompromised NSG mice. We then established T cell hybridoma clones from the AFP158-specific mouse CD8-T cells and identified three sets of paired TCR genes out of 5 hybridomas. Expression of the murine TCR genes redirected primary human T cells to bind HLA-A2/AFP158 tetramer. The TCR gene-engineered human T cells (TCR-T) specifically recognized HLA-A2+AFP+ HepG2 tumor cells and produced effector cytokines. Importantly, the TCR-T cells could specifically kill HLA-A2+AFP+ HepG2 tumor cells without significant toxicity to normal hepatocytes in vitro. Adoptive transfer of the AFP-specific human TCR-T cells could eradicate HepG2 tumors in NSG mice.
Conclusion
We have identified novel AFP-specific murine TCR genes that can redirect human T cells to specifically recognize and kill HCC tumor cells, and those AFP158-specific TCRs have a great potential to engineer a patient’s autologous T cells to treat HCC tumors.

Abstract
Peptide vaccines can be a successful and cost-effective way of generating T-cell responses against defined tumor antigens, especially when combined with immune adjuvants such as poly-IC. However, strong immune adjuvants can induce a collateral increase in numbers of irrelevant, nonspecific T cells, which limits the effectiveness of the peptide vaccines. Here, we report that providing prolonged IL2 signaling in the form of either IL2/anti-IL2 complexes or pegylated IL2 overcomes the competitive suppressive effect of irrelevant T cells, allowing the preferential expansion of antigen-specific T cells. In addition to increasing the number of tumor-reactive T cells, sustained IL2 enhanced the ability of T cells to resist PD-1-induced negative signals, increasing the therapeutic effectiveness of the vaccines against established tumors. This vaccination strategy using peptides and sustained IL2 could be taken into the clinic for the treatment of cancer. Cancer Immunol Res; 6(5); 617-27. ©2018 AACR.

Abstract
Recent advances in cancer immunology, such as the discovery of immune checkpoint inhibitors, have validated immune cells as potential key players for effective cancer treatment. The efficacy of these therapies seems to be codependent on a tumor-reactive T lymphocyte response. For many years, numerous attempts and strategies in developing vaccines to generate tumor-reactive T cells have yielded poor results in the clinic due to suboptimal immunogenicity and the inability to overcome an immunosuppressive tumor microenvironment. In this review, we summarize past and current advances in T cell vaccines and describe our experience in developing optimized methods for antigen/adjuvant selection and vaccine administration in order to induce powerful anti-tumor responses.

Abstract
Nasal natural killer/T-cell lymphoma (NNKTL) is an aggressive neoplasm with poor therapeutic responses and prognosis. The programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) pathway plays an important role in immune evasion of tumor cells through T-cell exhaustion. The aim of the present study was to examine the expression of PD-L1 and PD-1 molecules in NNKTL. We detected the expression of PD-L1 in biopsy samples from all of the NNKTL patients studied. PD-L1 was found on both malignant cells and tumor-infiltrating macrophages, while PD-1-positive mononuclear cells infiltrated the tumor tissues in 36% of patients. Most significantly, soluble PD-L1 (sPD-L1) was present in sera of NNKTL patients at higher levels as compared to healthy individuals and the levels of serum sPD-L1 in patients positively correlated with the expression of PD-L1 in lymphoma cells of tumor tissues. In addition, the high-sPD-L1 group of patients showed significantly worse prognosis than the low-sPD-L1 group. Furthermore, we confirmed that membrane and soluble PD-L1 was expressed on the surface and in the culture supernatant, respectively, of NNKTL cell lines. The expression of PD-L1 was observed in tumor tissues and sera from a murine xenograft model inoculated with an NNKTL cell line. Our results suggest that sPD-L1 could be a prognostic predictor for NNKTL and open up the possibility of immunotherapy of this lymphoma using PD-1/PD-L1 axis inhibitors.

Abstract
Inhibition of specific Akt isoforms in CD8+ T cells promotes favored differentiation into memory versus effector cells, the former of which are superior in mediating antitumor immunity. In this study, we investigated the role of upstream PI3K isoforms in CD8+ T-cell differentiation and assessed the potential use of PI3K isoform-specific inhibitors to favorably condition CD8+ T cells for adoptive cell therapy. The phenotype and proliferative ability of tumor antigen-specific CD8+ T cells was assessed in the presence of PI3K-α, -β, or -δ inhibitors. Inhibition of PI3K-δ, but not PI3K-α or PI3K-β, delayed terminal differentiation of CD8+ T cells and maintained the memory phenotype, thus enhancing their proliferative ability and survival while maintaining their cytokine and granzyme B production ability. This effect was preserved in vivo after ex vivo PI3K-δ inhibition in CD8+ T cells destined for adoptive transfer, enhancing their survival and also the antitumor therapeutic activity of a tumor-specific peptide vaccine. Our results outline a mechanism by which inhibitions of a single PI3K isoform can enhance the proliferative potential, function, and survival of CD8+ T cells, with potential clinical implications for adoptive cell transfer and vaccine-based immunotherapies.

Abstract
Stimulator of IFN genes (STING) spontaneously contributes to anti-tumor immunity by inducing type I interferons (IFNs) following sensing of tumor-derived genomic DNAs in the tumor-bearing host. Although direct injection of STING ligands such as cyclic diguanylate monophosphate (c-di-GMP) and cyclic [G(2',5')pA(3',5')p] (cGAMP) into the tumor microenvironment exerts anti-tumor effects through strong induction of type I IFNs and activation of innate and adaptive immunity, the precise events caused by STING in the tumor microenvironment remain to be elucidated. We describe here our finding that a CD45+ CD11bmid Ly6C+ cell subset transiently accumulated in mouse tumor microenvironment of 4T1 breast cancer, squamous cell carcinomas, CT26 colon cancer, or B16F10 melanoma tissue after intratumoral injection of cGAMP. The accumulated cells displayed a macrophage (M ) phenotype since the cells were positive for F4/80 and MHC class II and negative for Ly6G. Intratumoral cGAMP treatment did not induce Mφ accumulation in STING-deficient mice. Depletion of CD8+ T cell using anti-CD8 mAb impaired the anti-tumor effects of cGAMP treatment. Depletion of the Mφ using clodronate liposomes impaired the anti-tumor effects of cGAMP treatment. Functional analysis indicated that the STING-triggered tumor-migrating Mφ exhibited phagocytic activity, production of tumor necrosis factor alpha TNFα), and high expression levels of T cell-recruiting chemokines, Cxcl10 and Cxcl11, IFN-induced molecules, MX dynamin-like GTPase 1 (Mx1) and 2'-5' oligoadenylate synthetase-like 1 (Oasl1), nitric oxide synthase 2 (Nos2), and interferon beta 1 (Ifnb1). These results indicate that the STING-triggered tumor-migrating Mφ participate in the anti-tumor effects of STING-activating compounds.

Abstract
Mutations in tumor suppressor p53 remain a vital mechanism of tumor escape from apoptosis and senescence. Emerging evidence suggests that p53 dysfunction also fuels inflammation and supports tumor immune evasion, thereby serving as an immunological driver of tumorigenesis. Therefore, targeting p53 in the tumor microenvironment (TME) also represents an immunologically desirable strategy for reversing immunosuppression and enhancing antitumor immunity. Using a pharmacological p53 activator nutlin-3a, we show that local p53 activation in TME comprising overt tumor-infiltrating leukocytes (TILeus) induces systemic antitumor immunity and tumor regression, but not in TME with scarce TILeus, such as B16 melanoma. Maneuvers that recruit leukocytes to TME, such as TLR3 ligand in B16 tumors, greatly enhanced nutlin-induced antitumor immunity and tumor control. Mechanistically, nutlin-3a-induced antitumor immunity was contingent on two nonredundant but immunologically synergistic p53-dependent processes: reversal of immunosuppression in the TME and induction of tumor immunogenic cell death, leading to activation and expansion of polyfunctional CD8 CTLs and tumor regression. Our study demonstrates that unlike conventional tumoricidal therapies, which rely on effective p53 targeting in each tumor cell and often associate with systemic toxicity, this immune-based strategy requires only limited local p53 activation to alter the immune landscape of TME and subsequently amplify immune response to systemic antitumor immunity. Hence, targeting the p53 pathway in TME can be exploited to reverse immunosuppression and augment therapeutic benefits beyond tumoricidal effects to harness tumor-specific, durable, and systemic antitumor immunity with minimal toxicity.

Abstract
The success of adoptive T cell-based immunotherapy (ACT) in cancer is limited in part by the accumulation of myeloid-derived suppressor cells (MDSC), which block several T cell functions, including T cell proliferation and the expression of various cytotoxic mediators. Paradoxically, the inhibition of CD8+ T cell differentiation into cytotoxic populations increased their efficacy after ACT into tumor-bearing hosts. Therefore, we aimed to test the impact of conditioning CD8+ T cells with MDSC on their differentiation potential and ACT efficacy. Our results indicate that MDSC impaired the progression of CD8+ T cells into effector populations, without altering their activation status, production of IL-2, or signaling through the T cell receptor. In addition, culture of CD8+ T cells with MDSC resulted in an increased ACT anti-tumor efficacy, which correlated with a higher frequency of the transferred T cells and elevated IFNγ production. Interestingly, activated CD62L+ CD8+ T cells were responsible for the enhanced anti-tumor activity showed by MDSC-exposed T cells. Additional results showed a decreased protein synthesis rate and lower activity of the mammalian/mechanistic target of rapamycin (mTOR) in T cells conditioned with MDSC. Silencing of the negative mTOR regulator tuberous sclerosis complex-2 in T cells co-cultured with MDSC restored mTOR activity, but resulted in T cell apoptosis. These results indicate that conditioning of T cells with MDSC induces stress survival pathways mediated by a blunted mTOR signaling, which regulated T cell differentiation and ACT efficacy. Continuation of this research will enable the development of better strategies to increase ACT responses in cancer.

Abstract
OBJECTIVES Provide evidence based guidelines for tracheostomy in critically ill adult patients and identify areas needing further research. METHODS A task force composed of representatives of 10 member countries of the Pan-American and Iberic Federation of Societies of Critical and Intensive Therapy Medicine and of the Latin American Critical Care Trial Investigators Network developed recommendations based on the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS The group identified 23 relevant questions among 87 issues that were initially identified. In the initial search, 333 relevant publications were identified of which 226 publications were chosen. The task force generated a total of 19 recommendations: 10 positive (1B=3, 2C=3, 2D=4) and 9 negative (1B=8, 2C=1). A recommendation was not possible in six questions. CONCLUSION Percutaneous techniques are associated with a lower risk of infections compared to surgical tracheostomy. Early tracheostomy only seems to reduce the duration of ventilator use but not the incidence of pneumonia, the length of stay, or the long-term mortality rate. The evidence does not support the use of routine bronchoscopy guidance or laryngeal masks during the procedure. Finally, proper prior training is as important or even a more significant factor in reducing complications than the technique used.

Abstract
Substantial evidence indicates that immunotherapy is a feasible and effective approach for the treatment of numerous types of cancer. Among various immunotherapy options, peptide vaccines to generate antitumor T cells appear as promising candidates, because of their cost effectiveness and ease of implementation. Nevertheless, most peptide vaccines are notorious for being weekly immunogenic and, thus, optimization of the vaccination strategy is essential to achieve therapeutic effectiveness. In addition, effective peptide vaccines must stimulate both CD8 cytotoxic and CD4 helper T lymphocytes. Our group has been successful in designing effective peptide vaccination strategies for inducing CD8 T-cell responses in mouse tumor models. Here, we describe a somewhat similar, but distinct, peptide vaccination strategy capable of generating vast CD4 T-cell responses by combining synthetic peptides with toll-like receptor (TLR) agonists and OX40/CD40 costimulation. This vaccination strategy was efficient in overcoming immune tolerance to a self-tumor-associated antigen and generated significant antitumor effects in a mouse model of malignant melanoma. The optimized peptide vaccine also allowed the expansion of adoptively transferred CD4 T cells without the need for lymphodepletion and IL2 administration, generating effective antimelanoma responses through the enhancement of proliferative and antiapoptotic activities of CD4 T cells. These results have practical implications in the design of more effective T-cell-based immunotherapies. Cancer Immunol Res; 5(1); 72-83. ©2016 AACR.

Abstract
Synthetic peptide vaccines aim to elicit and expand tumor-specific T cells capable of controlling or eradicating the tumor. Despite the high expectations based on preclinical studies, the results of clinical trials using peptide vaccines have been disappointing. Thus, many researchers in the field have considered peptide vaccines as outdated and no longer viable for cancer therapy. However, recent progress in understanding the critical roles of immune adjuvants, modes of vaccine administration and T cell dynamics has lead to a rebirth of this approach and reconsidering the use of peptide vaccines for treating malignant disorders.

Abstract
The design of efficacious and cost-effective therapeutic vaccines against cancer remains both a research priority and a challenge. For more than a decade, our laboratory has been involved in the development of synthetic peptide-based anti-cancer therapeutic vaccines. We first dedicated our efforts in the identification and validation of peptide epitopes for both CD8 and CD4 T cells from tumor-associated antigens (TAAs). Because of suboptimal immune responses and lack of therapeutic benefit of peptide vaccines containing these epitopes, we have focused our recent efforts in optimizing peptide vaccinations in mouse tumor models using numerous TAA epitopes. In this focused research review, we describe how after taking lessons from the immune system's way of dealing with acute viral infections, we have designed peptide vaccination strategies capable of generating very high numbers of therapeutically effective CD8 T cells. We also discuss some of the remaining challenges to translate these findings into the clinical setting.

Abstract
Tumor immune escape has been a major problem for developing effective immunotherapy. The human leukocyte antigen G (HLA-G) is a non-classical MHC class I molecule whose primary function is to protect the fetus from the mother's immune system. While HLA-G is hardly found in normal adult tissues, various tumor cells are known to express it, aiding their escape from the immune system. Thus, HLA-G is an attractive immunotherapy target. CD4(+) helper T lymphocytes (HTLs) play an important role in the immune reaction against tumors by assisting in the generation and persistence of CD8(+) cytotoxic T lymphocytes (CTLs) or by displaying direct antitumor effects. We report here that HLA-G expression in breast cancer significantly correlates with a poor prognosis. Also, we describe that the MHC class II-binding peptide HLA-G26-40 was effective in eliciting tumor-reactive CD4(+) T cell responses. Furthermore, treatment with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine increased HLA-G expression in tumors and subsequently enhanced recognition by HLA-G26-40-specific HTLs. These findings predict that a combination immunotherapy targeting HLA-G together with a DNA methyltransferase inhibitor could be useful against some cancers.

Abstract
The tumor microenvironment is profoundly immunosuppressive. We show that multiple tumor types create intratumoral immune suppression driven by a specialized form of regulatory T cell (Treg) activation dependent on the PTEN (phosphatase and tensin homolog) lipid phosphatase. PTEN acted to stabilize Tregs in tumors, preventing them from reprogramming into inflammatory effector cells. In mice with a Treg-specific deletion of PTEN, tumors grew slowly, were inflamed, and could not create an immunosuppressive tumor microenvironment. In normal mice, exposure to apoptotic tumor cells rapidly elicited PTEN-expressing Tregs, and PTEN-deficient mice were unable to maintain tolerance to apoptotic cells. In wild-type mice with large established tumors, pharmacologic inhibition of PTEN after chemotherapy or immunotherapy profoundly reconfigured the tumor microenvironment, changing it from a suppressive to an inflammatory milieu, and tumors underwent rapid regression. Thus, the immunosuppressive milieu in tumors must be actively maintained, and tumors become susceptible to immune attack if the PTEN pathway in Tregs is disrupted.

Abstract
Abstract
Epigenetic modifications are a major component of regulating cell biology and, thus, have raised attention for their implications in cancer immunotherapies. In this regard, histone deacetylases (HDACs) have emerged as key players in orchestrating both tumor and immune response. Particularly HDAC6 has been identified as modulating the regulatory T-cell suppressive activity through HSP90. The uniqueness of HDAC6 in containing two enzymatic pockets allows the development of isotype-specific small molecule inhibitors. Here a novel role of HDAC6 in regulating anti-melanoma response is exploited and shown to have positive implications for tumor infiltration lymphocyte (TIL) therapy. Initially HDAC6 expression was evaluated in T-cell subsets from mouse, healthy human cells and melanoma patients. HDAC6 expression was decreased after T-cell activation as well as in the central memory TILs subset when compared to its naïve counterpart. To further investigate the role(s) of HDAC6 in T-cell anti-tumor responses, an HDAC6KO mouse model was utilized. Despite having normal lymphocyte compartments, melanoma growth was significantly delayed in HDAC6KO when comparing to age-, sex-match wild-type (WT) mice. Tumor-free HDAC6KO mice also displayed an enhanced T-cell response following melanoma-peptide vaccination, characterized by a less pronounced contraction phase of antigen-specific CD8+ T-cells. When systemically treated with the HDAC6 specific inhibitor ACY-1215, tumor growth was slightly reduced in melanoma-bearing mice. To address whether this was a direct effect on T-cell response, WT T-cells treated ex vivo with ACY-1215 were adoptively transferred to tumor-bearing WT mice. It was found that HDAC6 inhibition improved in vivo anti-tumor response and led to a modest accumulation of central memory T-cells in the lymph nodes. To further expand these results with a potential clinical application, previously frozen TILs from melanoma patients were thawed and treated with ACY-1215 during expansion in vitro. Accordingly, HDAC6 inhibition increased the percent of both CD8+ and CD4+ central memory T-cell subsets, as indicated by CD45RO, CD45RA, CCR7 and CD62L surface markers. To build upon these results, the expression of transcription factors involved in T-cell differentiation and polarization were evaluated. The transcription factor T-BET was found to be up-regulated in CD4+ and CD8+ TILs after in vitro expansion and treatment with ACY-1215, while there was a mild decrease in expression of GATA3 and RORgT in CD4+ TILs. This data is suggestive of CD4+ TIL polarization towards a pro-inflammatory Th1 phenotype. Moreover, both CD4+ and CD8+ TILs expanded and treated with ACY-1215 displayed enhanced Ki67 expression compared to the control treatment group, indicating higher proliferative capacity as a result of HDAC6 inhibition. To address if ACY-1215 treatment could ultimately improve T-cell cytotoxicity against melanoma, TILs from one melanoma patient were treated with ACY-1215 at the same time of in vitro expansion and then co-cultured with HLA matched melanoma. Treatment of TILs with ACY-1215 resulted in 20% more killing of target cells than the control group. The data presented so far suggests a positive effect of HDAC6 inhibition in generating and maintaining anti-tumor and peptide vaccination responses in vivo. While further investigation of cellular and molecular mechanisms is necessary, the results herein described provide rationale for targeting HDAC6 to improve cancer immunotherapy.

Abstract
Abstract
Adoptive T-cell therapy is an effective treatment for metastatic melanoma, achieving objective clinical responses in half of patients undergoing tumor infiltration lymphocyte (TIL) therapy. Epigenetic modifications are key players in regulating gene expression. Modulation of histone deacetylases (HDACs) has received attention for its implications in altering gene regulation. While HDAC pan-inhibition directly affects tumor growth, the immune system may be negatively impacted. Novel HDAC-selective inhibitors can ameliorate these undesirable effects. HDAC6 is unique in containing two catalytic domains, allowing for the development of isotype-selective inhibitors. Here a novel role of HDAC6 in T-cell immunity with important implications for adoptive cell therapy was explored. Initially a delay in B16 melanoma growth was observed in HDAC6KO mice (p<0.001 at day 19). Furthermore, tumor-free HDAC6KO mice vaccinated with melanoma antigen peptides displayed a mean of 30% antigen-specific circulating CD8+ T-cells versus 12% in WT mice. Moreover, HDAC6 expression was reduced over three fold in T-cells activated in vitro. To further investigate the role(s) of HDAC6 in anti-tumor T-cell responses, the HDAC6 selective inhibitor rocilinostat was utilized. Adoptive transfer of rocilinostat-treated T-cells conferred an increased anti-melanoma response in a B16 model (day 25 mean tumor volume 800 vs. 2200 cubic mm), characterized by accumulation of central memory T-cells in the lymph nodes. To directly address the clinical potential of targeting HDAC6, T-cells from healthy human donors and melanoma patient-derived TILs were treated with rocilinostat. A modest but consistent 5% increase in central memory phenotype in healthy CD4+ and CD8+ T-cells was observed. While a decrease in the naïve, effector and effector memory subsets occurred, no differences in cell viability were seen. Rocilinostat treatment of TILs derived from different cell preparations (e.g. tumor digest, pre- and post-rapid expansion in vitro) displayed up to a three-fold increase in central memory in three patients analyzed. Impressively, repeated in vitro treatment with rocilinostat further increased the proportion of central memory CD4+ and CD8+ T-cells. Intriguingly, initial results show that the transcription factor T-BET, involved in T-cell function, was upregulated in TILs after rocilinostat treatment and in vitro expansion. Functionally, activation of rocilinosat-treated TILs resulted in increased IFNg+CD107a+ T-cells. Ultimately, rocilinostat pre-treatment of TILs or concomitantly with tumor resulted in 70% killing of HLA matched melanoma cells, compared to 50% killing by control-treated TILs, both relative to melanoma only control. These preliminary data provide a rationale for targeting HDAC6 in T-cells to improve cancer immunotherapy.

Abstract
Therapeutic cancer vaccines are an attractive alternative to conventional therapies for treating malignant tumors, and successful tumor eradication depends primarily on obtaining high numbers of long-lasting tumor-reactive CD8+ T cells. Dendritic cell (DC)-based vaccines constitute a promising approach for treating cancer, but in most instances low immune responses and suboptimal therapeutic effects are achieved indicating that further optimization is required. We describe here a novel vaccination strategy with peptide-loaded DCs followed by a mixture of synthetic peptides, polyinosine-polycytidylic acid (poly-IC) and anti-CD40 antibodies (TriVax) for improving the immunogenicity and therapeutic efficacy of DC-based vaccines in a melanoma mouse model. TriVax immunization 7–12 d after priming with antigen-loaded DCs generated large numbers of long-lasting multiple antigen-specific CD8+ T cells capable of recognizing tumor cells. These responses were far superior to those generated by homologous immunizations with either TriVax or DCs. CD8+ T cells but not CD4+ T cells or NK cells mediated the therapeutic efficacy of this heterologous prime-boost strategy. Moreover, combinations of this vaccination regimen with programmed cell death-1 (PD-1) blockade or IL2 anti-IL2 antibody complexes led to complete disease eradication and survival enhancement in melanoma-bearing mice. The overall results suggest that similar strategies would be applicable for the design of effective therapeutic vaccination for treating viral diseases and various cancers, which may circumvent current limitations of cell-based cancer vaccines.

Abstract
Abstract
Using lentivector (lv) immunization and epitope-optimization, we have recently identified three CD8 epitopes in the hepatocellular carcinoma (HCC) associated antigen of murine alpha fetoprotein (AFP) that could effectively activate CD8 T cells in mice, resulting in potent antitumor effect that can completely prevent mice from tumor challenge and prevent carcinogen-induce autochthonous HCC. In this report, we studied whether the epitope-specific CD8 responses can be further enhanced by peptide boost and investigate if the newly identified epitope specific T cells can kill AFP+ tumor cells and have equal antitumor activity. We found that the lv-primed AFP-specific CD8 responses can be boosted by AFP peptides even at the peak of primary responses. As much as 20 folds increase of AFP-specific CD8 responses can be achieved by peptide boost. However, the kinetics and the antitumor effect of different epitope-specific CD8 responses are drastically different. While the epitope AFP499-specific CD8 T cells possess potent CTL activity against AFP+ tumor cells and generate strong antitumor effect in vivo, the AFP212-specific CD8 T cells have a very limited CTL activity and antitumor effect though they can produce high level of IFNg. The mechanisms underpinning the functional differences will be reported. This finding demonstrates that cancer vaccines must be able to elicit tumor-killing immune effector cells in order to generate antitumor effect.

Abstract
The median survival for metastatic melanoma is in the realm of 8-16 months and there are few therapies that offer significant improvement in overall survival. One of the recent advances in cancer treatment focuses on epigenetic modifiers to alter the survivability and immunogenicity of cancer cells. Our group and others have previously demonstrated that pan-HDAC inhibitors induce apoptosis, cell cycle arrest and changes in the immunogenicity of melanoma cells. Here we interrogated specific HDACs which may be responsible for this effect. We found that both genetic abrogation and pharmacologic inhibition of HDAC6 decreases in vitro proliferation and induces G1 arrest of melanoma cell lines without inducing apoptosis. Moreover, targeting this molecule led to an important upregulation in the expression of tumor associated antigens and MHC class I, suggesting a potential improvement in the immunogenicity of these cells. Of note, this anti-melanoma activity was operative regardless of mutational status of the cells. These effects translated into a pronounced delay of in vivo melanoma tumor growth which was, at least in part, dependent on intact immunity as evidenced by the restoration of tumor growth after CD4+ and CD8+ depletion. Given our findings, we provide the initial rationale for the further development of selective HDAC6 inhibitors as potential therapeutic anti-melanoma agents.

Abstract
Background: The expression of c-Met and its ligand HGF plays a critical role in cell proliferation and is involved in numerous malignancies. Because c-Met expression and its role in NK/T-cell lymphoma remain unclear, we studied the expression and function of c-Met in NK/T-cell lymphoma cells. In addition, we investigated the possibility that c-Met could function as a tumor-associated antigen for helper T lymphocytes (HTLs). Methods: We evaluated whether HGF and c-Met were expressed in NK/T-cell lymphoma and the capacity of predicted c-Met HTL epitopes to induce antitumor responses in vitro. In addition, c-Met inhibitor was evaluated for the ability to inhibit TGF-β production in tumor and subsequently increase HTL recognition. Results: c-Met and HGF were expressed in NK/T-cell lymphoma cell lines, nasal NK/T-cell lymphoma specimens and patient serum samples. Moreover, HGF was shown to promote NK/T cell lymphoma (NKTCL) proliferation in an autocrine manner. Furthermore, we have identified three novel c-Met HTL epitopes that were restricted by several HLA-DR molecules. Notably, peptide-induced HTL lines directly recognized and killed c-Met expressing NK/T-cell lymphomas and various epithelial solid tumors. The c-Met specific HTLs could also recognize dendritic cells (DCs) pulsed with c-Met expressing tumor cell lysates. In addition, we observed that c-Met inhibition augmented HTL recognition by decreasing TGF-β production by tumor cells. Lastly, autophagy partly regulated the HTL responses against tumors. Conclusions: We identified novel c-Met HTL epitopes that can elicit effective antitumor responses against tumors expressing c-Met. Our results provide the rationale of combining c-Met targeting therapy and immunotherapy for NKTCLs and epithelial tumors.

Abstract
Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T cells in cancer calls for a more precise definition of the CD8+ T cell immune phenotypes in cancer and the abandonment of the generic terms "pro-tumor" and "antitumor." Based on recent studies investigating the functions of CD8+ T cells in cancer, we here propose some guidelines to precisely define the functional states of CD8+ T cells in cancer.

Abstract
Ortiz et al. report the accumulation of immature myeloid cells in skin tissue of patients with inflammatory conditions, which predisposes to the development of cancer. Evidence links chronic inflammation with cancer, but cellular mechanisms involved in this process remain unclear. We have demonstrated that in humans, inflammatory conditions that predispose to development of skin and colon tumors are associated with accumulation in tissues of CD33+S100A9+ cells, the phenotype typical for myeloid-derived suppressor cells in cancer or immature myeloid cells (IMCs) in tumor-free hosts. To identify the direct role of these cells in tumor development, we used S100A9 transgenic mice to create the conditions for topical accumulation of these cells in the skin in the absence of infection or tissue damage. These mice demonstrated accumulation of granulocytic IMCs in the skin upon topical application of 12-O-tetradecanoylphorbol-13-acetate (TPA), resulting in a dramatic increase in the formation of papillomas during epidermal carcinogenesis. The effect of IMCs on tumorigenesis was not associated with immune suppression, but with CCL4 (chemokine [C-C motif] ligand 4)-mediated recruitment of IL-17–producing CD4+ T cells. This chemokine was released by activated IMCs. Elimination of CD4+ T cells or blockade of CCL4 or IL-17 abrogated the increase in tumor formation caused by myeloid cells. Thus, this study implicates accumulation of IMCs as an initial step in facilitation of tumor formation, followed by the recruitment of CD4+ T cells.
