Abstract
Tumor-infiltrating lymphocyte (TIL) density plays an important role in anti-tumor immunity and is associated with patient outcome in various human and canine malignancies. As a first assessment of the immune landscape of the tumor microenvironment in canine renal cell carcinoma (RCC), we retrospectively analyzed clinical data and quantified CD3, FoxP3, and granzyme B immunostaining in formalin-fixed paraffin-embedded tumor samples from 16 dogs diagnosed with renal cell carcinoma treated with ureteronephrectomy. Cell density was low for all markers evaluated. Increased numbers of intratumoral FoxP3 labelled (+) cells, as well as decreased granzyme B+: FoxP3+ TIL ratio, were associated with poor patient outcomes. Our initial study of canine RCC reveals that these tumors are immunologically cold and Tregs may play an important role in immune evasion.

Abstract
Conventional treatments have shown a limited efficacy for pancreatic cancer, and immunotherapy is an emerging option for treatment of this highly fatal malignancy. Neoantigen is critical to improving the efficacy of tumor-specific immunotherapy. The cancer and peripheral blood specimens from human leukocyte antigen (HLA)-A0201 positive pancreatic cancer patient were subjected to next-generation sequencing and bioinformatics analyses were performed to screen high-affinity and highly stable neoepitopes. The activation of cytotoxic T lymphocytes (CTLs) by the mutBCL2A111-20 neoepitope targeting B-cell lymphoma 2-related protein A1 (BCL2A1) mutant epitope was investigated, and the cytotoxicity of mutBCL2A111-20 neoepitope-specific CTLs to pancreatic cancer cells was evaluated. The mutBCL2A111-20 neoepitope was found to present a high immunogenicity and induce CTLs activation and proliferation, and was cytotoxic to mutBCL2A111-20 neoepitope-loaded T2 cells and pancreatic cancer PANC-1-Neo and A2-BxPC-3-Neo cells that overexpressed mutBCL2A111-20 neoepitopes, appearing a targeting neoepitope specificity. In addition, high BCL2A1 expression correlated with a low 5-year progress free interval (PFI) among pancreatic cancer patients. Our findings provide experimental supports to individualized T-cell therapy targeting mutBCL2A111-20 neoepitopes, and provide an option of immunotherapy for pancreatic cancer.

Abstract
Some viruses exhibit "rebound" when the administration of antiviral drugs is discontinued. Viral rebound caused by resistance mutations or latent reservoirs has been studied mathematically. In this study, we investigated the viral rebound due to other causes. Since immunity is weaker during antiviral treatment than without the treatment, drug discontinuation may lead to an increase in the viral load. We analyzed the dynamics of the number of virus-infected cells, cytotoxic T lymphocytes, and memory cells and identified the conditions under which the viral load increased upon drug discontinuation. If drug is administered for an extended period, a viral rebound occurs when the ratio of viral growth rate in the absence to that in the presence of the antiviral drug exceeds the "rebound threshold." We analyzed how the rebound threshold depended on the patient's conditions and the type of treatment. Mathematical and numerical analyses revealed that rebound after discontinuation was more likely to occur when the drug effectively reduced viral proliferation, drug discontinuation was delayed, and the processes activating immune responses directly were stronger than those occurring indirectly through immune memory formation. We discussed additional reasons for drugs to cause viral rebound more likely.

Abstract
Diospyros peregrina is a dioecious plant which is native to India. It belongs to the family of Ebenaceae and is extensively used to treat various ailments, such as leucorrhoea and other uterine-related problems. Though few studies have been on D. peregrina for their anti-tumour response, little is known. Therefore, this intrigued us to understand its immunomodulator capabilities on various types of cancer extensively. Our primary focus is on NSCLC (Non-Small Cell Lung Cancer), which is ranked as the second largest form of cancer in the world, and the treatments demand non-invasive agents to target NSCLC effectively. In an objective to generate an efficient Lung Cancer Associated Antigen (LCA) specific anti-tumour immune response, LCA was presented using dendritic cells (DCs) in the presence of D. peregrina fruit preparation (DFP). Moreover, we also investigated DFP's role in the differentiation of T-helper (TH) cells. Therefore, this study aimed at better LCA presentation mediated by DFP by activating the LCA pulsed DCs and T helper cell differentiation for better immune response. DCs were pulsed with LCA for tumour antigen presentation in vitro, with and without DFP. Differentially pulsed DCs were irradiated to co-culture with autologous and allogeneic lymphocytes. Extracellular supernatants were collected for the estimation of cytokine levels by ELISA. LDH release assay was performed to test Cytotoxic T lymphocytes (CTLs) mediated lung tumour cell cytotoxicity. Thus, DFP may be a potential vaccine to generate anti-LCA immune responses to restrict NSCLC.

Abstract
Cytotoxic T lymphocytes (CTLs) play critical antitumor roles, encompassing diverse subsets including CD4+, NK, and γδ T cells beyond conventional CD8+ CTLs. However, definitive CTLs biomarkers remain elusive, as cytotoxicity-molecule expression does not necessarily confer cytotoxic capacity. CTLs differentiation involves transcriptional regulation by factors such as T-bet and Blimp-1, although epigenetic regulation of CTLs is less clear. CTLs promote tumor killing through cytotoxic granules and death receptor pathways, but may also stimulate tumorigenesis in some contexts. Given that CTLs cytotoxicity varies across tumors, enhancing this function is critical. This review summarizes current knowledge on CTLs subsets, biomarkers, differentiation mechanisms, cancer-related functions, and strategies for improving cytotoxicity. Key outstanding questions include refining the CTLs definition, characterizing subtype diversity, elucidating differentiation and senescence pathways, delineating CTL-microbe relationships, and enabling multi-omics profiling. A more comprehensive understanding of CTLs biology will facilitate optimization of their immunotherapy applications. Overall, this review synthesizes the heterogeneity, regulation, functional roles, and enhancement strategies of CTLs in antitumor immunity, highlighting gaps in our knowledge of subtype diversity, definitive biomarkers, epigenetic control, microbial interactions, and multi-omics characterization. Addressing these questions will refine our understanding of CTLs immunology to better leverage cytotoxic functions against cancer.

Abstract
BACKGROUND Esophageal cancer (EC) is a global canker notorious for causing high mortality due to its relentless incidence rate, convoluted with unyielding recurrence and metastasis. However, these intricacies of EC are associated with an immoderate expression of NY-ESO-1 antigen, presenting a lifeline for adoptive T cell therapy. We hypothesized that naturally isolated higher-affinity T cell receptors (TCRs) that bind to NY-ESO-1 would allow T lymphocytes to target EC with a pronounced antitumor response efficacy. Also, targeting TRPV2, which is associated with tumorigenesis in EC, creates an avenue for dual-targeted therapy. We exploited the dual-targeting antitumor efficacy against EC. METHODS We isolated antigen-specific TCRs (asTCRs) from a naive library constructed with TCRs obtained from enriched cytotoxic T lymphocytes. The robustness of our asTCRs and their TCR-T cell derivatives, Tranilast (TRPV2 inhibitor), and their bivalent treatment were evaluated with prospective cross-reactive human-peptide variants and tumor cells. RESULTS Our study demonstrated that our naive unenhanced asTCRs and their TCR-Ts perpetuated their cognate HLA-A*02:01/NY-ESO-1(157-165) specificity, killing varying EC cells with higher cytotoxicity compared to the known affinity-enhanced TCR (TCRe) and its wild-type (TCR0) which targets the same NY-ESO-1 antigen. Furthermore, the TCR-Ts and Tranilast bivalent treatment showed superior EC killing compared to any of their monovalent treatments of either TCR-T or Tranilast. CONCLUSION Our findings suggest that dual-targeted immunotherapy may have a superior antitumor effect. Our study presents a technique to evolve novel, robust, timely therapeutic strategies and interventions for EC and other malignancies.

Abstract
Allogeneic hematopoietic stem cell transplantation (AHSCT) is an important modality in the treatment of acute leukemia and other hematologic disorders. The post-transplant period is associated with prolonged periods of impaired immune function. Delayed T-cell immune reconstitution is correlated with increased risk of viral, bacterial, and fungal infections. This risk increases with high intensity inductions regimens often required for alternative donor sources. Current therapies for prophylaxis and treatment of these infections are limited by poor efficacy and significant toxicity. Adoptive cell therapy with cytotoxic T lymphocytes (CTL) has proven to be both efficacious and safe in the management of post-transplant viral infections. Recent advances have led to faster production of CTLs and broadened applications for their use. In particular, the generation of third party CTLs has helped ameliorate the problems related to donor availability and product generation time. In this review we aim to describe both the history of CTL use and current advances in the field.

Abstract
The limited efficacy of immune checkpoint inhibitors (ICIs) in the treatment of advanced Esophageal Squamous Cell Carcinoma (ESCC) poses a challenge. Recent evidence suggests that tumor cells' insensitivity to cytotoxic T lymphocytes (CTLs) contributes to drug resistance against ICIs. Here, a particular tRNA-derived fragment called tRF-3024b has been identified as playing a significant role in tumor cell resistance to CTLs. Through tRF sequencing (tRF-seq), we observed a high expression of tRF-3024b in ESCC cells that survived co-culture with CTLs. Further in vitro studies demonstrated that tRF-3024b reduced the apoptosis of tumor cells when co-cultured with CTLs. The mechanism behind this resistance involves tRF-3024b promoting the expression of B-cell lymphoma-2 (BCL-2) by sequestering miR-192-5p, a microRNA that would normally inhibit BCL-2 expression. This means that tRF-3024b indirectly enhances the protective effects of BCL-2, reducing apoptosis in tumor cells. Rescue assays confirmed that the suppressive function of tRF-3024b relies on BCL-2. In summary, the tRF-3024b/miR-192-5p/BCL-2 axis sheds light on the crucial role of tRF-3024b in regulating BCL-2 expression. These findings offer valuable insights into strategies to enhance the response of ESCC to CTLs and improve the effectiveness of immunotherapy approaches in treating ESCC.

Abstract
In the field of cancer immunotherapy, the effectiveness of a method in which patient-derived T cells are genetically modified ex vivo and administered to patients has been demonstrated. However, problems remain with this method, such as (1) time-consuming, (2) costly, and (3) difficult to guarantee the quality. To overcome these barriers, strategies to regenerate T cells using iPSC technology are being pursued by several groups in the last decade. The authors have been developing a method by which specific TCR genes are introduced into iPSCs and T cells are generated from those iPSCs (TCR-iPSC method). At present, our group is preparing this approach for clinical trial, where iPSCs provided from the iPSC project are transduced with WT1 antigen-specific TCR that had been already clinically tested, and killer T cells are generated from such TCR-iPSCs, to be administered to acute myeloid leukemia patients. While the adoptive T cell therapies have been mainly directed to be used in cancer immunotherapy, it is possible to apply these approaches to viral infections. Strategies by other groups to regenerate various types of T cells from iPSCs will also be introduced.

Abstract
Neoantigen-reactive cytotoxic T lymphocytes play a vital role in precise cancer cell elimination. In this study, we demonstrate the effectiveness of personalized neoantigen-based T cell therapy in inducing tumor regression in two patients suffering from heavily-burdened metastatic ovarian cancer. Our approach involved the development of a robust pipeline for ex vivo expansion of neoantigen-reactive T lymphocytes. Neoantigen peptides were designed and synthesized based on the somatic mutations of the tumors and their predicted HLA binding affinities. These peptides were then presented to T lymphocytes through co-culture with neoantigen-loaded dendritic cells for ex vivo expansion. Subsequent to cell therapy, both patients exhibited significant reductions in tumor marker levels and experienced substantial tumor regression. One patient achieved repeated cancer regression through infusions of T cell products generated from newly identified neoantigens. Transcriptomic analyses revealed a remarkable increase in neoantigen-reactive cytotoxic lymphocytes in the peripheral blood of the patients following cell therapy. These cytotoxic T lymphocytes expressed polyclonal T cell receptors (TCR) against neoantigens, along with abundant cytotoxic proteins and pro-inflammatory cytokines. The efficacy of neoantigen targeting was significantly associated with the immunogenicity and TCR polyclonality. Notably, the neoantigen-specific TCR clonotypes persisted in the peripheral blood after cell therapy. Our findings indicate that personalized neoantigen-based T cell therapy triggers cytotoxic lymphocytes expressing polyclonal TCR against ovarian cancer, suggesting its promising potential in cancer immunotherapy.

Abstract
Low-dose metronomic (LDM) chemotherapy, the frequent and continuous use of low doses of conventional chemotherapeutics, is emerging as a promising form of chemotherapy utilization. LDM chemotherapy exerts immunomodulatory effects. However, the underlying mechanism is not fully understood. Here we found that suppressing tumor growth by LDM chemotherapy was dependent on the activation of CD8+T cells. LDM chemotherapy potentiated the cytotoxic function of CD8+T cells by stimulating cancer-cell autonomous type I interferon (IFN) induction. Mechanistically, LDM chemotherapy evoked mitochondrial dysfunction and increased reactive oxygen species (ROS) production. ROS triggered the oxidation of cytosolic mtDNA, which was sensed by cGAS-STING, consequently inducing type I IFN production in the cancer cells. Moreover, the cGAS-STING-IFN axis increased PD-L1 expression and predicted favorable clinical responses to chemoimmunotherapy. Antioxidant N-acetylcysteine inhibited oxidized mtDNA-induced type I IFN production and attenuated the efficacy of combination therapy with LDM chemotherapy and PD-L1 blockade. This study elucidates the critical role of intratumoral oxidized mtDNA sensing in LDM chemotherapy-mediated activation of CD8+T cell immune response. These findings may provide new insights for designing combinatorial immunotherapy for cancer patients.

Abstract
Prophylactic tumor vaccines hold great promise against tumor occurrence. However, their clinical efficacy remains low due to inadequate activation of strong-sustainable immunity. Herein, a biomembrane hydrogel was designed as a powerful single-shot prophylactic tumor vaccine. Mannose-decorated hybrid biomembrane (MHCM) modified with oxidized sodium alginate (OSA) was designed as a gelator (O-MHCM), where the hybrid biomembrane (HCM) is a hybridization of bacterial outer membrane vesicles (OMV) and tumor cell membranes (TCM). The O-MHCM enables quick gelation subcutaneously where the cysteine protease inhibitor E64 is encapsulated in hydrogel micropores. After a single vaccination of E64@O-MHCM hydrogel, MHCM and E64 are released sustainably due to OSA moiety degradation. The MHCM enables active targeting to dendritic cells (DC) and effective DC maturation. Meanwhile, the E64 enables sufficient antigen availability for subsequent cross presentation. Ultimately, strong and sustainable T lymphocyte-mediated immunity was elicited, demonstrating a strong prophylactic effect against breast tumors. This study provides a long-lasting platform to prevent tumor occurrence, opening an innovative avenue for the design of a single-shot prophylactic tumor vaccine. STATEMENT OF SIGNIFICANCE: Developing a single-shot prophylactic tumor vaccine to elicit strong-sustainable immunity is of great interest clinically. Here, a prophylactic tumor vaccine was designed using an injectable biomembrane hydrogel for achieving strong-sustainable immunity. The mannose-tailored hybrid biomembrane was modified with oxidized sodium alginate to result in a gelator, which enabled the formation of the hydrogel after subcutaneous injection. Cysteine protease inhibitor E64 was incorporated into the micropores of the hydrogel. The hydrogel induced strong-sustainable immunity through the continuous release of active components. This was facilitated by the mannose moiety, which enabled active targeting, as well as the antigen and adjuvant function of biomembrane, and the E64-enabled suppression of antigen degradation. The biomembrane hydrogel demonstrated powerful prevention of 4T1 breast tumors. This study offers an attractive strategy for designing a single-shot prophylactic tumor vaccine.

Abstract
BACKGROUND In individuals with malignancy or HIV-1 infection, antigen-specific cytotoxic T lymphocytes (CTLs) often display an exhausted phenotype with impaired capacity to eliminate the disease. Existing cell-based immunotherapy strategies are often limited by the requirement for adoptive transfer of CTLs. We have developed an immunotherapy technology in which potent CTL responses are generated in vivo by vaccination and redirected to eliminate target cells using a bispecific Redirector of Vaccine-induced Effector Responses (RoVER). METHODS Following Yellow fever (YF) 17D vaccination of 51 healthy volunteers (NCT04083430), single-epitope YF-specific CTL responses were quantified by tetramer staining and multi-parameter flow cytometry. RoVER-mediated redirection of YF-specific CTLs to kill antigen-expressing Raji-Env cells, autologous CD19+ B cells or CD4+ T cells infected in vitro with a full-length HIV-1-eGFP was assessed in cell killing assays. Moreover, secreted IFN-γ, granzyme B, and TNF-α were analyzed by mesoscale multiplex assays. FINDINGS YF-17D vaccination induced strong epitope-specific CTL responses in the study participants. In cell killing assays, RoVER-mediated redirection of YF-specific CTLs to autologous CD19+ B cells or HIV-1-infected CD4+ cells resulted in 58% and 53% killing at effector to target ratio 1:1, respectively. INTERPRETATION We have developed an immunotherapy technology in which epitope-specific CTLs induced by vaccination can be redirected to kill antigen-expressing target cells by RoVER linking. The RoVER technology is highly specific and can be adapted to recognize various cell surface antigens. Importantly, this technology obviates the need for adoptive transfer of CTLs.

Abstract
BACKGROUND and Purpose: Colorectal cancer (CRC) is one of the cancers with the highest incidence in which APC gene mutations occur in almost 80% of patients. This mutation leads to β-catenin aberrant accumulation and an uncontrolled proliferation. Apoptosis evasion, changes in the immune response and microbiota composition are also events that arise in CRC. Tetracyclines are drugs with proven antibiotic and immunomodulatory properties that have shown cytotoxic activity against different tumor cell lines. EXPERIMENTAL APPROACH The effect of tigecycline was evaluated in vitro in HCT116 cells and in vivo in a colitis-associated colorectal cancer (CAC) murine model. 5-fluorouracil was assayed as positive control in both studies. KEY RESULTS Tigecycline showed an antiproliferative activity targeting the Wnt/β-catenin pathway and downregulating STAT3. Moreover, tigecycline induced apoptosis through extrinsic, intrinsic and endoplasmic reticulum pathways converging on an increase of CASP7 levels. Furthermore, tigecycline modulated the immune response in CAC, reducing the cancer-associated inflammation through downregulation of cytokines expression. Additionally, tigecycline favored the cytotoxic activity of cytotoxic T lymphocytes (CTLs), one of the main immune defenses against tumor cells. Lastly, the antibiotic reestablished the gut dysbiosis in CAC mice increasing the abundance of bacterial genera and species, such as Akkermansia and Parabacteroides distasonis, that act as protectors against tumor development. These findings resulted in a reduction of the number of tumors and an amelioration of the tumorigenesis process in CAC. CONCLUSION AND IMPLICATIONS Tigecycline exerts a beneficial effect against CRC supporting the use of this antibiotic for the treatment of this disease.

Abstract
Immune suppressive factors of the tumor microenvironment (TME) undermine viability and exhaust the activities of the intratumoral cytotoxic CD8 + T lymphocytes (CTL) thereby evading anti-tumor immunity and decreasing the benefits of immune therapies. To counteract this suppression and improve the efficacy of therapeutic regimens, it is important to identify and understand the critical regulators within CD8 + T cells that respond to TME stress and tumor-derived factors. Here we investigated the regulation and importance of activating transcription factor-4 (ATF4) in CTL using a novel Atf4ΔCD8 mouse model lacking ATF4 specifically in CD8 + cells. Induction of ATF4 in CD8 + T cells occurred in response to antigenic stimulation and was further increased by exposure to tumor-derived factors and TME conditions. Under these conditions, ATF4 played a critical role in the maintenance of survival and activities of CD8 + T cells. Conversely, selective ablation of ATF4 in CD8 + T cells in mice rendered these Atf4ΔCD8 hosts prone to accelerated growth of implanted tumors. Intratumoral ATF4-deficient CD8 + T cells were under-represented compared to wild-type counterparts and exhibited impaired activation and increased apoptosis. These findings identify ATF4 as an important regulator of viability and activity of CD8 + T cells in the TME and argue for caution in using agents that could undermine these functions of ATF4 for anti-cancer therapies.

Abstract
Dendritic cells orient T cell responses via antigen presentation and provision of polarizing signals. The ability of human dendritic cells to polarize effector T cells can be assessed in mixed lymphocyte reactions. Here we describe a protocol that can be used with any human dendritic cell to assess their ability to polarize CD4+ T helper cells or CD8+ cytotoxic T cells.

Abstract
BACKGROUND Wilms' tumor 1 (WT1) is highly expressed in various solid tumors and hematologic malignancies. DSP-7888 (adegramotide/nelatimotide) Emulsion is an investigational therapeutic cancer vaccine comprising three synthetic epitopes derived from WT1. We evaluated the mechanism of action of DSP-7888 Emulsion, which is hypothesized to induce WT1-specific cytotoxic T lymphocytes (CTLs) and helper T lymphocytes (HTLs). METHODS The ability of nelatimotide and adegramotide to induce WT1-specific CD8+ T cells and CD4+ T cells was assessed in human peripheral blood mononuclear cells (PBMCs). The ability of DSP-7888 Emulsion to induce WT1-specific CTLs in vivo was assessed using human leukocyte antigen-I (HLA-I) transgenic mice. To assess how adegramotide, the helper peptide in DSP-7888 Emulsion, enhances WT1-specific CTLs, HLA-I transgenic mice were administered DSP-7888 or nelatimotide-only Emulsion. Interferon-gamma secretion under antigen stimulation by splenocytes co-cultured with or without tumor cells was then quantified. The effects of combination treatment with DSP-7888 Emulsion and an anti-programmed cell death protein 1 (PD-1) antibody on tumor volume and the frequency of tumor-infiltrating WT1-specific T cells were assessed in HLA-I transgenic mice implanted with WT1 antigen-positive tumors. RESULTS The peptides in DSP-7888 Emulsion were shown to induce WT1-specific CTLs and HTLs in both human PBMCs and HLA-I transgenic mice. Unlike splenocytes from nelatimotide-only Emulsion-treated mice, splenocytes from DSP-7888 Emulsion-treated mice exhibited high levels of interferon-gamma secretion, including when co-cultured with tumor cells; interferon-gamma secretion was further enhanced by concomitant treatment with anti-PD-1. HLA-I transgenic mice administered DSP-7888 Emulsion plus anti-PD-1 experienced significantly greater reductions in tumor size than mice treated with either agent alone. This reduction in tumor volume was accompanied by increased numbers of tumor-infiltrating WT1-specific CTLs. CONCLUSIONS DSP-7888 Emulsion can promote both cytotoxic and helper T-cell-mediated immune responses against WT1-positive tumors. Adegramotide enhances CTL numbers, and the CTLs induced by treatment with both nelatimotide and adegramotide are capable of functioning within the immunosuppressive tumor microenvironment. The ability of anti-PD-1 to enhance the antitumor activity of DSP-7888 Emulsion in mice implanted with WT1-positive tumors suggests the potential for synergy.

Abstract
CD8+ cytotoxic T lymphocytes (CTL) play a key role in anti-tumor immune response. They are therefore at the heart of current immunotherapy protocols against cancer. Despite current strategies to potentiate CTL responses, cancer cells can resist CTL attack, thus limiting the efficacy of immunotherapies. To optimize immunotherapy, it is urgent to develop rapid assays allowing to assess CTL-cancer cell confrontation at the lytic synapse.In this chapter, we describe a flow cytometry-based method to simultaneously assess the extent of CTL activation and of tumor cell reparative membrane turnover in CTL/target cell conjugates. Such a method can be performed using a limited number of cells. It can therefore be employed in clinical settings when only a few patient-derived cells might be available.

Abstract
Astragalus membranaceus is a widely used herbal medicine in Asia. It has been recognized as possessing various biological properties, however, studies on the activity of the A. membranaceus polysaccharide (AMP), a major component of A. membranaceus, on human peripheral blood dendritic cells (PBDCs) have not been thoroughly investigated. In this study, we found that AMP induced changes in dendritic morphology and the upregulation of activation marker expression and inflammatory cytokine production in human blood monocyte-derived dendritic cells (MDDCs). The AMP promoted the activation of both blood dendritic cell antigen 1+ (BDCA1+) and BDCA3+ PBDCs. AMP-induced secretion of cytokines in the peripheral blood mononuclear cells (PBMCs) was mainly due to PBDCs. Finally, activated BDCA1+ and BDCA3+ PBDCs by AMP elicited proliferation and activation of autologous T cells, respectively. Hence, these data demonstrated that AMPs could activate dendritic and T cells in human blood, and may provide a new direction for the application of AMPs in the regulation of human immunity.

Abstract
Lung cancer stays the preeminent cause of death worldwide. Despite recent advancements in chemotherapy, radiotherapy, and immunotherapy, the survival rate for people with advanced stages of the disease is still appalling. Moreover, there is a severe lack of reliable prognoses and indicators for classification in newly developed immunotherapies. A better understanding of immune cells is necessary to harness immune response mechanisms for therapeutic effects. Professional antigen-presenting cells are responsible for determining the fate of the immune response through the antigen processing and presentation pathway (APP). The most professional antigen-presenting cells (APC) include the dendritic cells (DC), macrophages, and B cells, which present antigens to the T-helper cells. Dendritic cells are significantly explored as a tool for immunotherapy owing to their precise ability to provoke and alter T-cell responses. Moreover, the role of tumor-associated macrophages (TAMs), an abundant leukocyte in lung cancer, is also a potential target for adjuvant anti-cancer therapies. In this review, we summarize the recent advances in our understanding of the various types of immunotherapy mapped out via professional antigen-presenting cells in lung cancer.

Abstract
Background Colorectal cancer (CRC) with pulmonary metastasis usually indicates a poor prognosis, whereas patients may benefit from adoptive cell therapy. Tumor-specific cytotoxic T lymphocytes (CTLs) have been reported as a promising treatment for CRC. However, the antitumor effect of CTLs remains limited partially due to insufficient production of effector cells via the activation by antigen-presenting dendritic cells (DCs). Method This study showed that a combination of CD40 mAb and Picibanil (OK-432) could significantly enhance the activation of CTLs by DCs, both in vitro and in vivo. Flow cytometry, colon cancer mouse model, and pathological staining were employed to demonstrate the specific functions. Results This approach promoted the maturation of DCs, augmented the production of stimulatory cytokines, and suppressed the secretion of inhibitory cytokines. Additionally, it facilitated the killing efficiency of CTLs via stimulating their proliferation while restraining the number of Tregs, concomitantly with the positive regulation of corresponding cytokines. Furthermore, the combined unit could hurdle the expansion of tumor cells on metastatic lungs in the colon cancer mouse model. Conclusion Collectively, the combination of CD40-mAb and OK-432 facilitated the maturation of DCs and enhanced the cytotoxicity of T cells, promising therapeutic approach against CRC.

Abstract
OBJECTIVE This study aims to elucidate the changes in the percentage of GPR56 and/or granzyme B (GZMB) positive cells in rheumatoid arthritis (RA) CD4 and CD8 T lymphocytes, and to explore their clinical value in diagnosing and reflecting the progression of RA. METHODS The percentages of GPR56 and/or GZMB positive cells were analyzed in peripheral blood (PB) and spleen T cells in a collagen-induced arthritis (CIA) model established in DBA/1 mice. The percentages of GPR56+ and/or GZMB+ cells were further analyzed in PBs from RA patients and healthy controls. Correlation analysis was performed between clinical indicators and GPR56+, GZMB+, and GPR56+ GZMB+ T cells. Receiver operating characteristic (ROC) curves were used to evaluate the value of GPR56 and GZMB in differentiating active and stable remitting RA. RESULTS GPR56+ levels were increased in CD4 and CD8 T cells in the PB of CIA mice. The percentages of GPR56+ and GZMB+ cells were increased in both CD4 and CD8 T cell subsets in patients with active RA. GPR56+, GZMB+, and GPR56+ GZMB+ cells were positively correlated with rheumatoid factor and DAS28. ROC analysis revealed that AUCs for GPR56+, GZMB+, and GPR56+ GZMB+ cell percentages to distinguish active RA from stable remission RA were 0.7106, 0.6941, 0.7024, with cut-off values of 16.35, 16.40, 14.80 in CD4 + T cells, and 0.8031, 0.8086, 0.8196 with cut-off values 60.25, 62.15, 40.15 in CD8 + T cells, respectively. CONCLUSIONS GPR56+ and/or GZMB+ T cells are up-regulated in patients with active RA and reflect their condition. The detection of GPR56 and GZMB is helpful for RA disease assessment.

Abstract
Background Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in dogs. It is characterized by the proliferation of neoplastic lymphocytes in the bone marrow, which are morphologically normal (mature), but non-functional. CLL in canines commonly originates in cytotoxic T lymphocytes (TCD8+), and although there is controversy regarding the prognostic value of the immunophenotype, this cell lineage may be associated with a good prognosis. Case Description A 10-year-old, entire female, mixed-breed dog was brought to the University Hospital of the Veterinary Faculty (UdelaR) for consultation because a routine pre-surgical check-up revealed lymphocytic leukocytosis, normocytic anemia, and hyperglobulinemia due to an oligoclonal gammopathy. The ultrasound revealed splenomegaly. PCR performed on blood was negative for Ehrlichia canis. Blood and bone marrow flow cytometry was performed to complement the diagnosis and carry out the immunophenotype, which showed CLL of CD8+ T-cell lineage. The clinical suspicion of CLL was confirmed by a myelogram. Chemotherapy treatment based on alkylating agents and glucocorticoids was established. So far, the patient has an overall survival of 13 months with a good response to treatment. Conclusion The combination of the immunophenotyping test, the myelogram, and the hematological and biochemical profile confirmed the presence of T-CLL in our patient. Flow cytometry, increasingly used in veterinary medicine, allowed us to confirm the diagnosis of CLL originating in cytotoxic T lymphocytes in our patient, through the presence of positive staining of primary antibodies specific for the canine species CD45, CD3, CD5, and CD8 and the absence of staining for CD4, CD21, and CD34.

Abstract
We evaluated the peripheral blood immune responses of lymphocytes in severe Coronavirus disease 2019 (COVID-19) patients in different stages of recovery using single-cell mass cytometry. The patients with prolonged hospitalization did not show recovery of B lymphocyte counts and CD4-positive T lymphocyte counts but did show abundant CD8-positive T lymphocytes. CD4 and CD8 T cells expressing high levels of T-bet and Granzyme B were more abundant in post-recovery patients. This study showed that cytotoxic Th1 and CD8 T cells are recruited to the peripheral blood long after recovery from COVID-19.

Abstract
Despite the many successes and opportunities presented by PD-1 blockade in cancer therapies, anti-PD-1 monoclonal antibodies still face multiple challenges. Herein we report a strategy based on a nanobody (Nb) to circumvent these obstacles. A new PD-1-blocking Nb (PD-1 Nb20) in combination with tumor-specific dendritic cell (DC)/tumor-fusion cell (FC) vaccine that aims to improve the activation, proliferation, cytokine secretion, and tumor cell cytotoxicity of CD8+ T-cells. This combination was found to effectively enhance the in vitro cytotoxicity of CD8+ T-cells to kill human non-small cell lung cancer (NSCLC) HCC827 cells, hepatocellular carcinoma (HCC) HepG2 cells, and tongue squamous cell carcinoma (TSCC) Tca8113 cells. Moreover, CD8+ T-cells pre-treated with PD-1 Nb20 and tumor-specific DC/tumor-FCs significantly suppressed the growth of NSCLC-, HCC- and TSCC-derived xenograft tumors and prolonged the survival of tumor-bearing mice, through promoting T-cell infiltration to kill tumor cells and inhibiting tumor angiogenesis. These data demonstrate that PD-1 Nb20 in synergy with DC/tumor-FC vaccine augment the broad spectrum of antitumor activity of CD8+ T-cells, providing an alternative and promising immunotherapeutic strategy for tumor patients who are T-cell-dysfunctional or not sensitive to anti-PD-1 therapy.

Abstract
Recent studies have revealed that treatment-resistant cancer stem-like cells (CSCs)/cancer-initiating cells (CICs) can be targeted by cytotoxic T lymphocytes (CTLs). CTLs recognize antigenic peptides derived from tumor-associated antigens; thus, the identification of tumor-associated antigens expressed by CSCs/CICs is essential. Human leucocyte antigen (HLA) ligandome analysis using mass spectrometry enables the analysis of naturally expressed antigenic peptides; however, HLA ligandome analysis requires a large number of cells and is challenging for CSCs/CICs. In this study, we established a novel bladder CSC/CIC model from a bladder cancer cell line (UM-UC-3 cells) using an ALDEFLUOR assay. CSCs/CICs were isolated as aldehyde dehydrogenase (ALDH)-high cells and several ALDHhigh clone cells were established. ALDHhigh clone cells were enriched with CSCs/CICs by sphere formation and tumorigenicity in immunodeficient mice. HLA ligandome analysis and cap analysis of gene expression using ALDHhigh clone cells revealed a distinctive antigenic peptide repertoire in bladder CSCs/CICs, and we found that a glutamate receptor, ionotropic, kainite 2 (GRIK2)-derived antigenic peptide (LMYDAVHVV) was specifically expressed by CSCs/CICs. A GRIK2 peptide-specific CTL clone recognized GRIK2-overexpressing UM-UC-3 cells and ALDHhigh clone cells, indicating that GRIK2 peptide can be a novel target for bladder CSC/CIC-targeting immunotherapy.

Abstract
Tumors evade immune surveillance by expressing Programmed Death-Ligand 1 (PD-L1), subsequently inhibiting CD8+ cytotoxic T lymphocyte function. Response of gastric cancer to immunotherapy is relatively low. Our laboratory has reported that Helicobacter pylori-induced PD-L1 expression within the gastric epithelium is mediated by the Hedgehog (Hh) signaling pathway. The PI3K/AKT/mTOR pathway is activated in gastric cancer and may have immunomodulatory potential. We hypothesize that Hh signaling mediates mTOR-induced PD-L1 expression. Patient-derived organoids (PDOs) were generated from gastric biopsies and resected tumor tissues. Autologous organoid/immune cell co-cultures were used to study the immunosuppressive function of MDSCs. NanoString Digital Spatial Profiling (DSP) of immune-related protein markers using FFPE slide-mounted tissues from gastric cancer patients was performed. DSP analysis showed infiltration of immunosuppressive MDSCs expressing Arg1, CD66b, VISTA and IDO1 within cancer tissues. Orthotopic transplantation of patient derived organoids (PDOs) resulted in the engraftment of organoids and the development of histology similar to that observed in the patient's tumor tissue. PDO/immune cell co-cultures revealed that PD-L1-expressing organoids were unresponsive to nivolumab in vitro in the presence of PMN-MDSCs. Depletion of PMN-MDSCs within these co-cultures sensitized the organoids to anti-PD-1/PD-L1-induced cancer cell death. Rapamycin decreased phosphorylated S6K, Gli2 and PD-L1 expression in PDO/immune cell co-cultures. Transcriptional regulation of PD-L1 by GLI1 and GLI2 was blocked by rapamycin. In conclusion, the PDO/immune cell co-cultures may be used to study immunosuppressive MDSC function within the gastric tumor microenvironment. The mTOR signaling pathway mediates GLI-induced PD-L1 expression in gastric cancer.

Abstract
Co-stimulatory and co-inhibitory molecules play a critical role in T cell function. Tumor cells escape immune surveillance by promoting immunosuppression. Immunotherapy targeting inhibitory molecules like anti-CTLA-4 and anti-PD-1/PD-L1 were developed to overcome these immunosuppressive effects. These agents have demonstrated remarkable, durable responses in a small subset of patients. The other mechanisms for enhancing anti-tumor activities are to target the stimulatory pathways that are expressed on T cells or other immune cells. In this review, we summarize current phase I/II clinical trials evaluating novel immunotherapies targeting stimulatory pathways and outline their advantages, limitations, and future directions.

Abstract
The presence of memory T cells in COVID-19 patients has been acknowledged, however the functional potency of memory responses is critical for protection. In this study, naïve, effector, effector memory, and central memory CD4+ and CD8+ T cells obtained from the COVID-19 survivors were re-exposed to autologous monocyte-derived DCs that were loaded with SARS-CoV-2 spike glycoprotein S1. Proliferation capacity, CD25, 4-1BB, and PD-1 expression, and IFN-γ, IL-6, granzyme, granulysin, and FasL secretion were enhanced in CD4+ and CD8+ effector memory and central memory T cells. Albeit being at heterogeneous levels, the memory T cells from the individuals with COVID-19 history possess functional capacities to reinvigorate anti-viral immunity against SARS-CoV-2.

Abstract
The immune system is the core defense against cancer development and progression. Failure of the immune system to recognize and eliminate malignant cells plays an important role in the pathogenesis of cancer. Tumor cells evade immune recognition, in part, due to the immunosuppressive features of the tumor microenvironment. Immunotherapy augments the host immune system to generate an antitumor effect. Immune checkpoints are pathways with inhibitory or stimulatory features that maintain self-tolerance and assist with immune response. The most well-described checkpoints are inhibitory in nature and include the cytotoxic T lymphocyte-associated molecule-4 (CTLA-4), programmed cell death receptor-1 (PD-1), and programmed cell death ligand-1 (PD-L1). Molecules that block these pathways to enhance the host immunologic activity against tumors have been developed and become standard of care in the treatment of many malignancies. Only a small percentage of patients have meaningful responses to these treatments, however. New pathways and molecules are being explored in an attempt to improve responses and application of immune checkpoint inhibition therapy. In this review, we aim to elucidate these novel immune inhibitory pathways, potential therapeutic molecules that are under development, and outline particular advantages and challenges with the use of each one of them.

Abstract
As an attractive tumor-associated antigen (TAA), Wilms tumor gene 1 (WT1) is usually overexpressed in malignant hematological diseases. In recent years, WT1-specific adoptive immunotherapy has been the "hot spot" for tumor treatment. The main immunotherapeutic techniques associated with WT1 include WT1-specific cytotoxic T lymphocytes (CTLs), vaccine, and T cell receptor (TCR) gene therapy. WT1-based adoptive immunotherapy exhibited promising anti-tumorous effect with tolerable safety. There are still many limitations needed to be improved including the weak immunogenetics of WT1, immune tolerance, and short persistence of the immune response. In this review, we summarized the progress of productive technologies and the clinical or preclinical investigations of WT1-specific immunotherapy in hematological diseases.

Abstract
Autophagy is quintessential for the maintenance of cellular homeostasis in all eukaryotic cells, explaining why both normal and malignant cells benefit from proficient autophagic responses. Moreover, autophagy is intimately involved in the immunological control of malignant transformation, tumor progression and response to therapy. However, the net effect of autophagy activation or inhibition on the natural growth or therapeutic response of tumors evolving in immunocompetent hosts exhibits a considerable degree of context dependency. Here, we discuss the complex cross-talk between autophagy and immuno-oncology as delineated by genetic and pharmacological approaches in mouse models of cancer.

Abstract
Gut microbiota, the largest microbial community living in the human body, exerts a variety of metabolic, structural, and functional actions. In particular, it is essential for the full immune system development and maturation, as demonstrated by studies on germ-free animals, showing immune impairment at different levels. Gut microbiota shapes the immune responses by promoting immune tolerance toward food antigens and commensals in the steady state. This process is orchestrated by a complex network of both microbial and human cells and molecular mediators. Microbiota eubiosis is fundamental in establishing a correct balance between tolerance and immunity. Contrarily, microbiota dysbiosis is correlated with alterations in the immune balance, as evidenced in intestinal pathologies characterized by aberrant immune responses, such as inflammatory bowel disease and celiac disease, in which either break of tolerance against commensals or microbial dysbiosis is reported. On the other hand, a role for gut microbiota in stimulating the cytotoxic immune response in contexts of immunosuppression, like the ones featuring tumors and vaccinations, is emerging. The bifaceted role of gut microbiota in the delicate balance between tolerance and immunity could be exploited in order to develop pioneering therapeutic strategies, complementary to the pharmacological ones, thus representing a field worthy of further studies specifically focused on this topic.

Abstract
CXCL11 which can bind to two different chemokine receptors, CXCR3 and CXCR7, has found a prominent place in current tumor research. In this chapter, we mainly discuss the current evidence on the role of the immune response of CXCL11 in tumor microenvironment (TME). The diverse functions of CXCL11 include inhibiting angiogenesis, affecting the proliferation of different cell types, playing a role in fibroblast directed carcinoma invasion, increasing adhesion properties, suppressing M2 macrophage polarization, and facilitating the migration of certain immune cells. In addition, we discussed the application of CXCL11 as an adjuvant to various mainstream anti-cancer therapies and the future challenges in the application of CXCL11 targeted therapies.

Abstract
Cytotoxic T lymphocytes (CTL) and natural killer (NK) cells are required for host defense. They destroy malignant target cells like cancer cells. Among metal cations, Ca2+ plays a prescinded role for CTL and NK cytotoxicity as it is the only cation used as ubiquitous second messenger. Measuring intracellular Ca2+ concentrations [Ca2+]int in single cells has greatly changed our understanding of Ca2+ signaling. Yet, comparing the role of Ca2+ in the pre-[Ca2+]int and [Ca2+]int measurement era reveals that even in the pre-[Ca2+]int measurement era (before 1980), the functions of Ca2+ and some other metal cations for the cytotoxic immune response were well established. It was even shown that Ca2+ influx across the plasma membrane but not Ca2+ release from intracellular sources is relevant for lymphocyte cytotoxicity and that very little Ca2+ is needed for efficient lymphocyte cytotoxicity against cancer cells. In the [Ca2+]int measurement era after 1980, many of the important findings were better and more quantitatively refined and in addition the molecules important for Ca2+ transport were defined. The unexpected finding that there is a Ca2+ optimum of CTL and NK cell cytotoxicity deserves some attention and may be important for anti-cancer therapy.

Abstract
Asbestos exposure is known to cause malignant mesothelioma, which is associated with poor prognosis. We focused on and examined the effect of asbestos exposure on the differentiation and function of cytotoxic T lymphocytes (CTLs). CTLs have the ability to specifically attack tumor cells after being differentiated from naïve CD8+ T cells following antigen stimulation. Exposure to chrysotile B asbestos suppressed the differentiation of CTLs during the mixed lymphocyte reaction (MLR) and was associated with a decrease in proliferation of CD8+ T cells. Additionally, in an effort to investigate the mechanism associated with suppressed CTL differentiation upon exposure to asbestos, we focused on IL-2, a cytokine involved in T cell proliferation. Our findings indicated that insufficient levels of IL-2 are not the main cause for the suppressed induction of CTLs by asbestos exposure, although they suggest potential improvement in the suppressed CTL function. Furthermore, the functional properties of peripheral blood CD8+ lymphocytes from asbestos-exposed individuals with pleural plaque (PP) and patients with malignant mesothelioma (MM) were examined. MM patients showed lower perforin levels in CD8+ lymphocytes following stimulation compared with PP-positive individuals. The production capacity of IFN-γ in the MM group tended to be lower compared with healthy volunteers or PP-positive individuals. In an effort to determine whether chronic and direct asbestos exposure affected the function of CD8+ T cells, cultured human CD8+ T cells were employed as an in vitro model and subjected to long-term exposure to chrysotile (CH) asbestos. This resulted in decreased levels of intracellular perforin and secreted IFN-γ. Those findings underlie the possibility that impaired CD8+ lymphocyte function is caused by asbestos exposure, which fail to suppress the development of MM. Our studies therefore reveal novel effects of asbestos exposure on CTLs, which might contribute towards the development and implementation of an effective strategy for the prevention and cure of malignant mesothelioma.

Abstract
BACKGROUND Bullous skin disorders are induced by different pathomechanisms and several are emergent, including Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Rapid diagnostic methods for SJS/TEN or cytotoxic T-lymphocyte (CTL)-mediated bullous disorders are crucial for early treatment. Granulysin, primarily expressed by CTLs, is a specific cytotoxic protein responsible for SJS/TEN and similar skin reactions. OBJECTIVE To assess granulysin levels in blister fluids to differentiate SJS/TEN and similar CTL-mediated bullous reactions from other autoimmune bullous disorders. METHODS Using ELISA, we measured granulysin in blister fluids from patients with bullous skin disorders, including SJS/TEN, erythema multiforme major, bullous fixed-drug eruption, bullous lupus erythematosus, paraneoplastic pemphigus, pemphigus vulgaris, bullous pemphigoid, purpura fulminans-related bullae, and hand-foot syndrome/hand-foot-skin reactions. We compared serum and blister granulysin levels in patients with SJS/TEN presenting varying severity, monitoring serial granulysin levels from acute to late stages. RESULTS Overall, 144 patients presenting with bullous skin disorders were enrolled. Blister granulysin levels (mean ± SD) in CTL-mediated disorders, including TEN (n = 28; 3938.7 ± 3475.7), SJS-TEN overlapping (n = 22; 1440.4 ± 1179.6), SJS (n = 14; 542.0 ± 503.2), erythema multiforme major (n = 7; 766.3 ± 1073.7), generalized bullous fixed-drug eruption (n = 10; 720.4 ± 858.3), and localized bullous fixed-drug eruption (n = 16; 69.0 ± 56.4), were significantly higher than in non-CTL-mediated bullous disorders (P < .0001), including bullous lupus erythematosus (n = 3; 22.7 ± 20.1), paraneoplastic pemphigus (n = 3; 20.3 ± 8.6), pemphigus vulgaris (n = 3; 4.4 ± 2.8), bullous pemphigoid (n = 18; 4.0 ± 2.7), purpura fulminans (n = 4; 5.9 ± 5.5), and hand-foot syndrome/hand-foot-skin reactions (n = 6; 4.6 ± 3.5). Blister granulysin levels correlated with clinical severity of SJS/TEN (P < .0001). CONCLUSIONS Determination of blister granulysin levels is a noninvasive and useful tool for rapid differential diagnosis of SJS/TEN and other similar CTL-mediated bullous skin disorders for treatment selection.

Abstract
Glucose uptake into lymphocytes is accomplished by non-concentrative glucose carriers of the GLUT family (GLUT1, GLUT3, GLUT4, GLUT6) and/or by the Na+-coupled glucose carrier SGLT1. The latter accumulates glucose against glucose gradients and is still effective at very low extracellular glucose concentrations. Signaling involved in SGLT1 expression and activity includes protein kinase A (PKA), protein kinase C (PKC), serum- and glucocorticoid-inducible kinase (SGK1), AMP-activated kinase (AMPK), and Janus kinases (JAK2 and JAK3). Glucose taken up is partially stored as glycogen. In hypoxic environments, such as in tumors as well as infected and inflamed tissues, lymphocytes depend on energy production from glycogen-dependent glycolysis. The lack of SGLT1 may compromise glycogen storage and thus lymphocyte survival and function in hypoxic tissues. Accordingly, in mice, genetic knockout of sglt1 compromised bacterial clearance following Listeria monocytogenes infection leading to an invariably lethal course of the disease. Whether the effect was due to the lack of sglt1 in lymphocytes or in other cell types still remains to be determined. Clearly, additional experimental effort is required to define the role of glucose transport by GLUTs and particularly by SGLT1 for lymphocyte survival and function, as well as orchestration of the host defense against tumors and bacterial infections.

Abstract
The present study was aimed to investigate the regulatory effect of Nitric oxide donor andrographolide (Q-1) on cellular immunity in patients with chronic hepatitis B. Peripheral blood mononuclear cells (PBMCs) were isolated from patients with chronic hepatitis B. Cell viability was assessed using 3‑(4,5‑dimethyl‑thiazol‑2‑yl)‑2,5‑diphenyl‑2H‑tetrazolium bromide (MTT) assay. The levels of expression of interferon gamma (IFN-γ), interleukin 4 (IL-4), interleukin 10 (IL-10) and tumor necrosis factor α (TFN-α) in PBMCs of patients with chronic hepatitis B were determined using real-time quantitative polymerase chain reaction (qRT-PCR). Anti-HBV effect of isolated HBV DNA was also assessed in vitro. Q-1 had no significant effect on the viability of Vero and isolated PBMCs (p > 0.05). The expression of IFN-γ in PBMCs of control patients significantly and time-dependently increased after treatment with Q-1, but the expressions of IL-4 and IL-10 in PBMCs of patients with chronic hepatitis B were decreased significantly and time-dependently (p < 0.05). The function of Th1 cells was significantly enhanced by Q-1 treatment (p < 0.05). The mean replication of HBV DNA in HepG2cells at the three concentrations of Q-1 and adefovir were 3.96 × 106, 4.13 × 106 and 4.53 × 106 copies/mL, respectively. There was no significant difference in the expression of HBV DNA among the concentration levels. These results indicate that andrographolide enhances the function of HBV-specific T cells in patients with chronic hepatitis B.

Abstract
The respective effects of tissue alarmins interleukin (IL)-15 and interferon beta (IFNβ), and IL-21 produced by T cells on the reprogramming of cytotoxic T lymphocytes (CTLs) that cause tissue destruction in celiac disease is poorly understood. Transcriptomic and epigenetic profiling of primary intestinal CTLs showed massive and distinct temporal transcriptional changes in response to tissue alarmins, while the impact of IL-21 was limited. Only anti-viral pathways were induced in response to all the three stimuli, albeit with differences in dynamics and strength. Moreover, changes in gene expression were primarily independent of changes in H3K27ac, suggesting that other regulatory mechanisms drive the robust transcriptional response. Finally, we found that IL-15/IFNβ/IL-21 transcriptional signatures could be linked to transcriptional alterations in risk loci for complex immune diseases. Together these results provide new insights into molecular mechanisms that fuel the activation of CTLs under conditions that emulate the inflammatory environment in patients with autoimmune diseases.

Abstract
Gap junctions (GJs) are clusters of intercellular connexin-formed channels found at the plasma membrane that allow direct communication between the cytoplasm of adjacent cells. Numerous reports have described GJs as modulators of key immunological processes, including in anti-tumor immune responses. Here, we described a simple flow cytometry method to test in vitro antigen-dependent GJ-mediated cell-to-cell coupling between cytotoxic T cells and target melanoma cells.

Abstract
Immunotherapeutic strategies based on Epstein-Barr virus (EBV) latent membrane protein 2 (LMP2) antigen-specific cytotoxic T lymphocytes (CTLs) have been proven to boost LMP2-specific CTL responses in patients with nasopharyngeal carcinoma (NPC). Such strategies can produce clinical benefits in some patients with NPC. Currently, the major challenge limiting the use of immunotherapy for NPC is its low clinical response rate. The efficacy of immunotherapy based on EBV-LMP2 specific CTLs depends mainly on their cytotoxic activity, but no studies have been conducted to elucidate this activity. In this study, laser confocal scanning microscopy (LCSM) and real-time cell analysis (RTCA) were used to evaluate the killing function and its underlying mechanism of LMP2-specific CTLs. LCSM showed that LMP2-specific CTLs recognize and kill target cells expressing viral escape protein LMP2, and that the killing rate is related to the number of CTLs adhering to the target cells. LMP2-specific CTL-mediated cytotoxicity is rate limited by the time required for effective contact and recognition between CTLs and target cells. RTCA showed that the protective effect of LMP2-specific CTLs required an appropriate effector-to-target ratio, and that LMP2-specific CTLs could not eradicate residual target cells at a low effector-to-target ratio. Moreover, our results revealed that LMP2-specific CTL responses involve two independent but complementary mechanisms: the perforin/granzyme and Fas/FasL pathways. Therefore, we have elucidated, for the first time, the selective cytotoxicity and mechanism by which LMP2-specific CTLs induced by the rAd-LMP2 vaccine kill target cells and have explored the killing mode and several key parameters of killing mediated by LMP2-specific CTLs. Our study will contribute to the knowledge of vaccines targeting EBV-LMP2 and to the improvement of immunotherapeutic strategies.

Abstract
Antibodies targeting PD1 receptor have emerged as a promising therapeutic strategy against multiple types of solid cancers. However, relatively low complete response rates observed with anti-PD1 mAb monotherapy emphasizes the importance of testing new immunotherapeutic combinations. The production of extracellular adenosine in solid tumors was recently identified as a major immunosuppressive pathway, targeting this pathway would enhance the therapeutic activity of anti-PD1 mAbs. In this study, we evaluated the anti-tumor activity and mechanism of action of caffeine and anti-PD1 mAb combination therapy against carcinogen- and cell line-induced tumors. Our results demonstrate that combination therapy enhanced the anti-tumor activity and prolonged overall survival period against 3-MCA-induced tumors. In addition, combination therapy showed a significant anti-tumor activity against B16F10 melanoma tumors. We found that combination therapy showed additive increase in infiltration of CD4+ and CD8+ T lymphocytes into the B16F10 melanoma tumors. On the other hand, combination therapy showed significant decrease in infiltration of CD4+CD25+ T regulatory cells. We further investigated whether the observed anti-tumor effect of caffeine and anti-PD1 mAb combination therapy is mediated through the release of cytokines. We found that caffeine and anti-PD1 mAb combination therapy significantly increased intra-tumoral TNF-α and IFN-γ levels. Our work suggests that administration of caffeine and anti-PD1 mAb harness the therapeutic potential of effector T cells in vivo possibly due to combined blockade of PD1 and adenosine-A2A receptor pathway. This study provides the scientific basis for testing combination regimens of caffeine and anti-PD1 mAbs for sustained tumor control in cancer patients.

Abstract
BACKGROUND & AIMS CD100 is constitutively expressed on T cells and can be cleaved from the cell surface by matrix metalloproteases (MMPs) to become soluble CD100 (sCD100). Both membrane-bound CD100 (mCD100) and sCD100 have important immune regulatory functions that promote immune cell activation and responses. This study investigated the expression and role of mCD100 and sCD100 in regulating antiviral immune responses during HBV infection. METHODS mCD100 expression on T cells, sCD100 levels in the serum, and MMP expression in the liver and serum were analysed in patients with chronic HBV (CHB) and in HBV-replicating mice. The ability of sCD100 to mediate antigen-presenting cell maturation, HBV-specific T cell activation, and HBV clearance were analysed in HBV-replicating mice and patients with CHB. RESULTS Patients with CHB had higher mCD100 expression on T cells and lower serum sCD100 levels compared with healthy controls. Therapeutic sCD100 treatment resulted in the activation of DCs and liver sinusoidal endothelial cells, enhanced HBV-specific CD8 T cell responses, and accelerated HBV clearance, whereas blockade of its receptor CD72 attenuated the intrahepatic anti-HBV CD8 T cell response. Together with MMP9, MMP2 mediated mCD100 shedding from the T cell surface. Patients with CHB had significantly lower serum MMP2 levels, which positively correlated with serum sCD100 levels, compared with healthy controls. Inhibition of MMP2/9 activity resulted in an attenuated anti-HBV T cell response and delayed HBV clearance in mice. CONCLUSIONS MMP2/9-mediated sCD100 release has an important role in regulating intrahepatic anti-HBV CD8 T cell responses, thus mediating subsequent viral clearance during HBV infection. LAY SUMMARY Chronic hepatitis B virus (HBV) infection is a major public health problem worldwide. The clearance of HBV relies largely on an effective T cell immune response, which usually becomes dysregulated in chronic HBV infection. Our study provides a new mechanism to elucidate HBV persistence and a new target for developing immunotherapy strategies in patients chronically infected with HBV.

Abstract
Background: Immune cells recognize tumor antigens presented on major histocompatibility complex class I (MHC-I) molecule. Increase of MHC-I molecular expression makes tumor cells more susceptible to lysis by immune cells. Methods: Tumor lysate vaccine was prepared to damage glioma cells including cell lines and primary cultured cells from surgical samples. The enhanced effect of histone deacetylase inhibitors (HDACi) to tumor lysate vaccine was observed. The expressions of MHC-I pathway molecules were detected by flow cytometry and western blot after HDACi treatment. Cell apoptosis and cell lysis were measured following blocking cytotoxic T lymphocyte (CTL) pathway. Tumor size and mice survival were analyzed in combinative treatment with HDACi and tumor lysate. Results: HDACi up-regulated the expressions of MHC-I pathway molecules, and enhanced the recognition and killing of immune cells, which was activated by tumor lysate. Activated antigen specific immune responses regulated CTL activity, and HDACi promoted immune response through cytotoxic effect of CTL. Anti-tumor effect of tumor lysate pulse immunogenicity in vivo was elevated by HDACi due to up-regulation of antigen presentation. Conclusions: Our study showed that HDACi enhanced recognition of glioma cell by immune cells and sensitivity of tumor immunotherapy, and improved the anti-tumor effect of tumor lysate vaccine through activating CTL immune response. These pharmacological molecular mechanisms of increasing immune recognition suggest that epigenetic modulation is a promising strategy for sensitizing immunotherapy for glioma treatment.

Abstract
Immunotherapy is a developing but very promising arsenal to treat cancer. Acquiring a more potent and effective approach in cancer immunotherapy is always the ultimate pursuance. CTL-based therapies are highly acclaimed recently due to its direct killing property. However, difficulty in obtaining adequate number of CTLs is still a major obstacle. In previous studies, it is shown that pluripotent stem cell-derived cytotoxic T lymphocytes (CTL)-especially the genetically engineered tumor antigen-specific CTLs-may serve as a good candidate for this goal. Here we introduce a novel approach in generating tumor antigen-specific CTLs from induced pluripotent stem cells (iPSCs) by using both in vitro and in vivo priming mechanisms for the tumor management in a murine melanoma model.

Abstract
Using subunit vaccines, e.g., based on peptide or protein antigens, to teach the immune system to kill abnormal host cells via induction of cytotoxic T lymphocytes (CTL) is a promising strategy against intracellular infections and cancer. However, customized adjuvants are required to potentiate antigen-specific cellular immunity. One strong CTL-inducing adjuvant is the liposomal cationic adjuvant formulation (CAF)09, which is composed of dimethyldioctadecylammonium (DDA) bromide, monomycoloyl glycerol (MMG) analogue 1 and polyinosinic:polycytidylic acid [poly(I:C)]. However, this strong CTL induction requires intraperitoneal administration because the vaccine forms a depot at the site of injection (SOI) after subcutaneous (s.c.) or intramuscular (i.m.) injection, and depot formation impedes the crucial vaccine targeting to the cross-presenting dendritic cells (DCs) residing in the lymph nodes (LNs). The purpose of the present study was to investigate the effect of polyethylene glycol (PEG) grafting of CAF09 on the ability of the vaccine to induce antigen-specific CTL responses after s.c. administration. We hypothesized that steric stabilization and charge shielding of CAF09 by PEGylation may reduce depot formation at the SOI and enhance passive drainage to the LNs, eventually improving CTL induction. Hence, the vaccine (antigen/CAF09) was post-grafted with a novel type of anionic PEGylated peptides based on GDGDY repeats, which were end-conjugated with one or two PEG1000 moieties, resulting in mono- and bis-PEG-peptides of different lengths (10, 15 and 20 amino acid residues). For comparison, CAF09 was also grafted by inclusion of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-methoxy(PEG)-2000 (DSPE-PEG2000) in the bilayer structure during preparation. Grafting of CAF09 with either type of PEG resulted in charge shielding, evident from a reduced surface charge. Upon s.c. immunization of mice with the model antigen ovalbumin (OVA) adjuvanted with PEGylated CAF09, stronger CTL responses were induced as compared to immunization of mice with unadjuvanted OVA. Biodistribution studies confirmed that grafting of CAF09 with DSPE-PEG2000 improved the passive drainage of the vaccine to LNs, because a higher dose fraction was recovered in DCs present in the draining LNs, as compared to the dose fraction detected for non-PEGylated CAF09. In conclusion, PEGylation of CAF09 may be a useful strategy for the design of an adjuvant, which induces CTL responses after s.c. and i.m. administration. In the present studies, CAF09 grafted with 10 mol% DSPE-PEG2000 is the most promising of the tested adjuvants, but additional studies are required to further elucidate the potential of the strategy.

Abstract
Hemophagocytic lymphohistiocytosis (HLH) includes primary HLH (pHLH) and secondary HLH (sHLH). Mutations that cause abnormal functions in natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) are frequently identified in pHLH. However, why NK cells and CTLs exhibit abnormal functions in sHLH remains unclear. Here, we demonstrated that NK cells in sHLH exhibited a high expression of inhibitory receptor NKG2A and a low expression of activating receptor NKG2D. Besides, the expression of HLA-E on lymphocyte, the adaptor of NKG2A on NK cells, was elevated in sHLH. Moreover, CTLs in sHLH patients expressed a higher level of functional exhaustion markers PD-1, TIM-3 and LAG-3 as well as a lower secretion of IFN-γ and CD107a upon stimulation. In addition, the expression of MHC-I on lymphocytes was decreased. Taken together, our study indicates a potentially pathological mechanism of sHLH and may open up new avenues for the development of immunotherapies against sHLH.
