Abstract
CD4+ CD25+ FOXP3+ T regulatory cells (Tregs) are a subset of the immunomodulatory cell population that can inhibit both innate and adaptive immunity by various regulatory mechanisms. In hepatic microenvironment, proliferation, plasticity, migration, and function of Tregs are interrelated to the remaining immune cells and their secreted cytokines and chemokines. In normal conditions, Tregs protect the liver from inflammatory and auto-immune responses, while disruption of this crosstalk between Tregs and other immune cells may result in the progression of chronic liver diseases and the development of hepatic malignancy. In this review, we analyze the deviance of this protective nature of Tregs in response to chronic inflammation and its involvement in inducing liver fibrosis, cirrhosis, and hepatocellular carcinoma. We will also provide a detailed emphasis on the relevance of Tregs as an effective immunotherapeutic option for autoimmune diseases, liver transplantation, and chronic liver diseases including liver cancer.

Abstract
BACKGROUND There is considerable heterogeneity in clinical behavior and survival outcomes in patients with cholangiocarcinoma (CCA), and the prognosis of CCA patients is poor. We proposed lymphocyte to monocyte ratio (LMR) as a novel prognostic element for CCA patients with hepatic resection in present study. METHODS By retrospectively analyzing the clinical data of 145 CCA patients with hepatic resection, we determined the optimal LMR cutoff value according to the receiver operating characteristic (ROC). We comparatively analyzed the clinical features of CAA patients between low LMR group and high LMR group, mainly including overall survival (OS) analysis by using the Kaplan-Meier method, univariate and multivariate Cox regression. RESULTS We found there was a longer OS in CCA patients of the high LMR group than the low LMR group. The total median OS of cholangiocarcinoma patients were 13.6 months, and the OS of low LMR group was markedly lower than the high LMR group. The 1-year, 3-year, and 5-year OS of high LMR group were respectively 62.9%, 32.4%, and 16.4%, and were significantly higher the cholangiocarcinoma patients of low LMR group (40.2%, 16.4%, and 0%). Multivariate regression analyses showed that preoperative cholangitis, elevated CEA level and nerve invasion were risk factors for the OS of cholangiocarcinoma patients, while the high LMR level and postoperative treatment were protective factors for the OS of cholangiocarcinoma patients. CONCLUSIONS Preoperative LMR was a vital prognostic factor to predict the prognosis of CCA patients with hepatic resection and provided additional prognostic value beyond standard clinicopathological parameters.

Abstract
Objective To investigate the association between pretreatment prognostic nutritional index (PNI) and clinical survival outcomes for advanced-stage cancer patients treated with immune checkpoint inhibitors (ICIs). Methods We conducted a comprehensive literature search to identify eligible studies concerning the relationship between pretreatment PNI and survival outcomes in advanced cancer patients treated with ICIs. Published data were extracted and pooled odds ratio (pOR) for objective response rate (ORR), disease control rate (DCR), and pooled hazard ratio (pHR) for overall survival (OS), progressive-free survival (PFS), along with 95% confidence intervals (95% CIs) were calculated. Results Twelve studies with 1,359 participants were included in our study. A higher level of PNI indicated a greater ORR (pOR = 2.17, 95% CI = 1.52–3.10) and favorable DCR (pOR = 2.48, 95% CI = 1.87–3.29). Low PNI was associated with a shorter OS (pHR = 2.24, 95% CI = 1.57–3.20) and unfavorable PFS (pHR = 1.61, 95% CI = 1.37–1.88). Conclusion Low PNI might be an effective biomarker of poor tumor response and adverse prognosis of advanced cancer patients with ICIs. Further studies are needed to verify the prognostic value of PNI in clinical practice.

Abstract
Immune checkpoint blocking based on the PD-1/PD-L1 pathway has shown exciting results in various types of cancer. However, due to the off-target effect of PD-1/PD-L1 blocker, low tumor immunogenicity and tumor immunosuppressive microenvironment, a significant proportion of patients do not benefit from this treatment. Here, we constructed a novel multifunctional metal complex Fe/PEI-Tn by the coordination of polyethyleneimine (PEI) with Fe3+ and the modification of bifunctional peptides Tn containing the cell penetrating peptide (TAT) and nuclear localization signal peptide (NLS), which was coated with hyaluronic acid (HA) to prolong the circulation time in vivo. Fe/PEI-Tn can condensate PD-L1 trap plasmid (pPD-L1 trap) and mediate PD-L1 trap protein expression in tumor tissues in situ, thus blocking the PD-1/PD-L1 pathway. Besides, Fe/PEI-Tn metal complex itself can act as an immune adjuvant to activate macrophages, reverse the phenotype of pro-tumor M2-type macrophages, and promote anti-tumor immunity. Meanwhile, Fe/PEI-Tn treatment can induce damage in tumor cells and release tumor-specific antigens into tumor microenvironment, thus stimulating anti-tumor immune response. Studies showed that HA/Fe/PEI-Tn/pPD-L1 trap complexes could promote the immune activation of tumor tissues and effectively delay tumor growth. This strategy provides a new direction for tumor combination therapy based on PD-1/PD-L1 blockade.

Abstract
Urachal carcinoma (UrC) is an exceedingly rare tumor and lacks effective treatment. Herein, we characterized an immune microenvironment characteristic of UrC in detail and identified its implications for prognosis and immunotherapy. In total, 37 resections of UrC were stained for CD20, CD3, CD4, CD8, FOXP3, CD68, HLA-DR, CD163, PD1, and PD-L1, as well as mismatch repair protein including MSH2, MSH6, MLH1, and PMS2 by immunohistochemistry. Intratumoral and peritumoral immune cell densities or the proportion of PD1 and PD-L1 expression alongside MSH2, MSH6, MLH1, and PMS2 status were manually evaluated using the whole slide. UrC patients with the number of tertiary lymphoid structures (TLS) per slide tended to be higher in tumors with dMMR (p = 0.1919), and tumors with higher number of TLS tended to have longer OS (p = 0.0940) and DFS (p = 0.0700). High densities of CD3+ T, CD8+ T, and CD68+ cells were significantly associated with worse OS and DFS (both p<0.05). Increased intratumoral (p = 0.0111) and peritumoral (p = 0.0485) CD8+ T cell densities were significantly associated with PD-L1 expression or increasing proportion of PD-L1 expression on immune cells. Similarly, increased intratumoral (p = 0.0008) and peritumoral (p = 0.063) CD8+ T cell densities were significantly associated with increasing proportion of PD1 expression on immune cells. Tumors with PD-L1 positive expression on immune cells had a significantly increased proportion of PD1 expression (p = 0.0121). High peritumoral CD8+ T cell density (>73.7/mm2) was significantly associated with worse OS (p = 0.0120) and DFS (p = 0.00095). The number of TLS seems to be considered not only as histopathological characteristics in predicting MMR status of UrC, but also as a prognostic or therapeutic biomarker, and we also provide some important suggestions for targeting PD-1/PD-L1 checkpoint in UrC.

Abstract
Hepatocellular carcinoma (HCC) is a severe type of primary liver cancer with high postoperative recurrence. The prognosis predictability of tumor-infiltrating leukocytes (TILs) for patients who underwent HCC resection has been widely reported. However, limited information is available about TIL trafficking, which is also crucial for HCC patients.We included tumor tissue samples and clinical data from 89 HCC patients in this study and performed immunohistochemistry for CD3, CD8, FoxP3, and CD31. TILs were measured using an algorithm for quantification of tumor immune stroma (QTiS). Intratumoral microvessels were counted using Weidner's method. We first examined correlations among them and analyzed their relationships with clinical and survival data.Intratumoral microvessel density (iMVD) was significantly correlated with infiltration of CD3+ (r = 0.338, P = .001) and CD8+ (r = 0.320, P = .002) cells, but not FoxP3+ (r = 0.153, P = .152) cells. After multivariate analysis, higher infiltration of CD3+ (P = .038) independently showed significant predictability on better overall survival after resection of HCC. Although no influence of CD3+ (P = .386) and CD8+ (P = .648) cells were found on general disease-free survival, infiltration of CD3+ (P = .012), tumor size (P = .032) and albumin (P = .007) cells independently predicted late-phase disease-free survival. No significant relationships regarding iMVD, and infiltration of FoxP3+ cells with overall and disease-free survival were found.Our data suggest that increased iMVD could enrich tumor-infiltrating CD3+ cells. Infiltrated CD3+ cells could help to better predict both the overall and late-phase disease-free survival after resection of HCC.

Abstract
Image-guided locoregional therapies (LRTs) are a crucial asset in the treatment of hepatocellular carcinoma (HCC), which has proven to be characterized by an impaired antitumor immune status. LRTs not only directly destroy tumor cells but also have an immunomodulating role, altering the tumor microenvironment with potential systemic effects. Nevertheless, the immune activation against HCC induced by LRTs is not strong enough on its own to generate a systemic significant antitumor response, and it is incapable of preventing tumor recurrence. Currently, there is great interest in the possibility of combining LRTs with immunotherapy for HCC, as this combination may result in a mutually beneficial and synergistic relationship. On the one hand, immunotherapy could amplify and prolong the antitumoral immune response of LRTs, reducing recurrence cases and improving outcome. On the other hand, LTRs counteract the typical immunosuppressive HCC microenvironment and status and could therefore enhance the efficacy of immunotherapy. Here, after reviewing the current therapeutic options for HCC, we focus on LRTs, describing for each of them the technique and data on its effect on the immune system. Then, we describe the current status of immunotherapy and finally report the recently published and ongoing clinical studies testing this combination.

Abstract
In order to reverse tumor immunosuppressive microenvironment and improve antitumor immune effect based on immune checkpoint blocking, a mannose-modified liposome-based CpG ODNs and PD-L1 antagonistic peptides (P) co-delivery system (HA/M-Lipo CpG-P) was constructed, in which hyaluronic acid (HA) coating was supposed to improve the systemic circulation stability and thereby promote its accumulation in tumor tissues. When the HA/M-Lipo CpG-P complexes enter the tumor tissues, HA will be hydrolyzed under the action of hyaluronidase, exposing P peptides. Then, P peptides linked by octapeptides that can be cleaved by matrix metalloproteinases (MMPs) are released into tumor tissues under the action of MMPs, exerting a blocking effect in the PD-1/PD-L1 pathway. The M-Lipo CpG complexes can recognize macrophage surface mannose receptors through its surface modified mannose molecules, and promote the intracellular delivery of CpG ODNs, thereby activating macrophages. The results showed that HA/M-Lipo CpG-P complexes successfully reversed M2-type macrophages in tumor microenvironment (TME) to M1, thereby activating anti-tumor related immune cells and inhibiting tumor growth. Moreover, the HA/M-Lipo CpG-P complexes showed a better tumor inhibitory effect than the HA/M-Lipo CpG or the HA/M-Lipo-P (monotherapy) treatment groups. Overall, HA/M-Lipo CpG-P complexes provide a promising co-delivery strategy for targeting tumors to improve the antitumor effect based on immune checkpoint blockade.

Abstract
Primary liver cancer (PLC) is one of the most common malignancies in China, where it ranks second in mortality and fifth in morbidity. Currently, liver transplantation, hepatic tumor resection, radiofrequency ablation, and molecular-targeted agents are the major treatments for hepatocellular carcinoma (HCC). Overall, HCC has a poor survival rate and a high recurrence rate. Tumor-infiltrating lymphocytes (TILs) have been discovered to play essential roles in the development, prognosis, and immunotherapy treatment of HCC. As the major component cells of TILs, T cells are also proved to show antitumor and protumor effects in HCC. Foxp3+, CD8+, CD3+, and CD4+ T lymphocytes are the broadly studied subgroups of TILs. This article reviews the roles and mechanisms of different tumor-infiltrating T lymphocyte subtypes in HCC.

Abstract
This study aims to evaluate the predictive value of the prognostic nutritional index (PNI) and albumin-bilirubin grade (ALBI) for the postoperative prognosis of hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC) patients undergoing radical hepatectomy (RH). Besides, we seek to identify novel prognosis indicators for HBV-HCC patients. Between April 2009 and March 2015, this work enrolled 868 patients diagnosed with HBV-HCC and undergoing RH in the Liver Surgery Department, West China Hospital, Sichuan University (WCHSU). The basic information, laboratory examination indicators, pathological reports, and follow-up data of patients were included. SPSS 22.0 statistical software was used for statistical data analyses. Platelet (PLT), alpha-fetoprotein (AFP), maximum diameter (max-D), number of tumors (Number), degree of differentiation (DD), Microvascular invasion situation (MVI), satellite focus situation (SF), PNI, and ALBI were the independent risk factors for both overall survival (OS) and disease-free survival (DFS) of HBV-HCC patients undergoing RH. Taking PNI = 46 and ALBI = - 2.80 as cut-off values, the OS and DFS of the PNI-high group were significantly higher than those of the PNI-low group. Meanwhile, the OS and DFS of the ALBI-low group were significantly higher than those of the ALBI-high group; the OS and DFS of the PNI-high + ALBI-low group were significantly higher than those of the PNI-low + ALBI-high group. Xie prognostic index (XPI) was the independent risk factor for both OS and DFS of HBV-HCC patients undergoing RH. The OS and DFS of the XPI-high group were significantly higher than those of the XPI-low group. This paper reveals that preoperative PNI and ALBI can predict the OS and DFS of HBV-HCC patients undergoing RH. Their impact on the prognosis of HBV-HCC patients is insignificant, however, it cannot be ignored. XPI can precisely predict the prognosis of HBV-HCC patients undergoing RH, nonetheless, its effect requires additional research for validation.

Abstract
Current immune-based therapies signify a major advancement in cancer therapy; yet, they are not effective in the majority of patients. Physically based local destruction techniques have been shown to induce immunologic effects and are increasingly used in order to improve the outcome of immunotherapies. The various local destruction methods have different modes of action and there is considerable variation between the different techniques with respect to the ability and frequency to create a systemic anti-tumor immunologic effect. Since the abscopal effect is considered to be the best indicator of a relevant immunologic effect, the present review focused on the tissue changes associated with this effect in order to find determinants for a strong immunologic response, both when local destruction is used alone and combined with immunotherapy. In addition to the T cell-inflammation that was induced by all methods, the analysis indicated that it was important for an optimal outcome that the released antigens were not destroyed, tumor cell death was necrotic and tumor tissue perfusion was at least partially preserved allowing for antigen presentation, immune cell trafficking and reduction of hypoxia. Local treatment with controlled low level hyperthermia met these requisites and was especially prone to result in abscopal immune activity on its own.

Abstract
The lymphocyte-C-reactive protein ratio (LCR) is a recently described inflammation-based score, and it remains unclear which is the optimal inflammation-based score among patients with hepatocellular carcinoma (HCC) who underwent transarterial chemoembolization (TACE). A large cohort of HCC patients (n=1625) who underwent TACE as the initial treatment were enrolled in the present study. Inflammation-based scores, including the Glasgow Prognostic Score (GPS), modified Glasgow Prognostic Score (mGPS), high-sensitivity modified Glasgow Prognostic Score (Hs-mGPS), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), systemic immune-inflammation index (SII), and LCR, were all related to the survival of HCC patients, but only the LCR score was a significant and independent predictor in multivariate analysis (hazard ratio: 1.45; 95% confidence interval: 1.27-1.65; P<0.001). Further analysis showed that the LCR score stably and consistently differentiated subgroup patients with distinct prognoses. The predictive accuracies of the LCR score (0.70, 0.68, and 0.68 for 1-, 3-, and 5-year C-index, respectively) were superior to the other inflammatory-based scores (0.60-0.64, 0.58-0.62, and 0.58-0.62 for 1-, 3-, and 5-year C-index, respectively). The LCR score was an independent prognostic indicator for HCC patients who underwent TACE, and it was superior to the other inflammation-based scores in prognostic ability.

Abstract
BACKGROUND & AIMS The lymphocyte-C-reactive protein ratio (LCR) is a novel inflammatory-based score, based solely on the lymphocyte and C-reactive protein. We aimed to clarify the prognostic value of the LCR score in intrahepatic cholangiocarcinoma (ICC) patients after resection. METHODS We compared the prognostic accuracy of the LCR score with other inflammatory-based scores in this large, multicentre cohort study. The independent variables associated with overall survival (OS) were explored in both the primary (n = 228) and validation cohorts (n = 135). Harrell's concordance index (C-index) was used to compare the predictive ability of all the assessed inflammatory-based scores. RESULTS The LCR score was differentiated two groups of ICC patients with distinct prognoses (1-, 3-, and 5-year OS rates: 94.4%, 66.3%, and 59.3%; and 66.6%, 45.6%, and 32.7%, respectively) (P < .001). Multivariate analysis showed that the LCR score, as well as the TNM stage and preoperative CA19-9 level, were independently associated with OS. The predictive accuracy of the LCR score (c score: 0.634) was superior to that of the other inflammatory-based scores (c scores: 0.508-0.615). These findings were supported by the external validation cohort. CONCLUSION The LCR score is stable and consistently the best prognostic score and may offer as a simple, objective and discriminatory method in facilitating the risk stratification of ICC patients.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease associated with damage to multiple organs and glands. The most common clinical manifestations are dry eyes, dry mouth, and enlarged salivary glands. Currently, CD4+ T lymphocytes are considered to be key factors in the immunopathogenesis of pSS, but various studies have shown that CD8+ T lymphocytes contribute to acinar injury in the exocrine glands. Therefore, in this review, we discussed the classification and features of CD8+ T lymphocytes, specifically describing the role of CD8+ T lymphocytes in disease pathophysiology. Furthermore, we presented treatment strategies targeting CD8+ T cells to capitalize on the pathogenic and regulatory potential of CD8+ T lymphocytes in SS to provide promising new strategies for this inflammatory disease.

Abstract
Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related mortality worldwide. Much recent research has delved into understanding the underlying molecular mechanisms of HCC pathogenesis, which has revealed to be heterogenous and complex. Two major hallmarks of HCC include: (i) a hijacked immunometabolism and (ii) a reprogramming in metabolic processes. We posit that the gut microbiota is a third component in an entanglement triangle contributing to HCC progression. Besides metagenomic studies highlighting the diagnostic potential in the gut microbiota profile, recent research is pinpointing the gut microbiota as an instigator, not just a mere bystander, in HCC. In this chapter, we discuss mechanistic insights on atypical immunometabolism and metabolic reprogramming in HCC, including the examination of tumor-associated macrophages and neutrophils, tumor-infiltrating lymphocytes (e.g., T-cell exhaustion, regulatory T-cells, natural killer T-cells), the Warburg effect, rewiring of the tricarboxylic acid cycle, and glutamine addiction. We further discuss the potential involvement of the gut microbiota in these characteristics of hepatocarcinogenesis. An immediate highlight is that microbiota metabolites (e.g., short chain fatty acids, secondary bile acids) can impair anti-tumor responses, which aggravates HCC. Lastly, we describe the rising 'new era' of immunotherapies (e.g., immune checkpoint inhibitors, adoptive T-cell transfer) and discuss for the potential incorporation of gut microbiota targeted therapeutics (e.g., probiotics, fecal microbiota transplantation) to alleviate HCC. Altogether, this chapter invigorates for continuous research to decipher the role of gut microbiome in HCC from its influence on immunometabolism and metabolic reprogramming.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a malignancy exhibiting the highest lethality. The present study aimed to identify different immune-related clusters in HCC and a robust tumor gene signature to facilitate the prognosis prediction for HCC patients. METHODS For the 375 HCC cases collected from the dataset of Cancer Genome Atlas (TCGA), their overall survival (OS) and immune-related genes (IRGs) expression patterns were collected. Thereafter, consensus clustering was employed for grouping and functional enrichment, whereas the ESTIMATE algorithm and the CIBERSORT algorithm were used in subsequent assessment. Immunohistochemistry (IHC) was conducted to verify the protein expression of model genes in HCC and adjacent tissues. RESULTS According to consensus clustering with 93-survival related IRGs, a total of five subgroups were found. These five clusters had different prognoses, immune statuses, and expression of immune checkpoints. Afterwards, 11 genes were enrolled for constructing the OS-related prediction model for TCGA HCC cases, which was then validated using the database of International Cancer Genome Consortium (ICGC). The protein expression of LCN2, S100A10, FABP6, PLXNA1, KITLG and OXTR were enhanced in HCC tissues relative to that in normal hepatic tissues, while the protein expression of S100A1, CCL26, CMTM4, IL1RN and RARG were reduced in HCC compared with normal tissues. In addition, different immunocyte infiltration levels between low- and high- groups were further examined. CONCLUSIONS According to our results, the IRGs-based classifications assist in explaining the HCC heterogeneity, which may help to develop the more efficient individualized treatments.

Abstract
The pathogenesis of hepatocellular carcinoma (HCC) is a multistep process, involving the progressive accumulation of molecular alterations and transcriptomic alterations. The Forkhead-box (FOX) transcription factor family is characterized by its unique DNA binding domain (FKH or winged-helix domain). Human FOX family consists of about 17 subfamilies, at least 43 members. Some of them are liver-enriched transcription factors, suggesting that they may play a crucial role in the development or/and functions of the liver. Dysregulation of FOX transcription factors may contribute to the pathogenesis of HCC because they can activate or suppress the expression of various tumor-related molecules, and pinpoint different molecular and cellular events. Here we summarized, analyzed and discussed the status and the functions of the human FOX family of transcription factors in HCC, aiming to help the further development of them as potential therapeutic targets or/and diagnostic/prognostic markers for HCC.

Abstract
Use of immune checkpoint inhibitors (ICIs) in hepatocellular carcinoma (HCC) has been partially successful. However, most HCC patients do not respond to immunotherapy. HCC has been shown to induce several immune suppressor mechanisms in patients. These suppressor mechanisms include involvement of myeloid-derived suppressor cells, regulatory T-cells, functionally impaired dendritic cells (DCs), neutrophils, monocytes, and tumor associated macrophages. The accumulation of immunosuppressive cells may lead to an immunosuppressive tumor microenvironment as well as the dense fibrotic stroma which may contribute to immune tolerance. Our laboratory has been investigating different cellular mechanisms of immune suppression in HCC patients. In vitro as well as in vivo studies have demonstrated that abrogation of the suppressor cells enhances or unmasks tumor-specific antitumor immune responses. Two or three effective systemic therapies including ICIs and/or molecular targeted therapies and the addition of innovative combination therapies targeting immune suppressor cells may lead to increased immune recognition with a greater tumor response. We reviewed the literature for the latest research on immune suppressor cells in HCC, and here we provide a comprehensive summary of the recent studies in this field.

Abstract
Purpose It has been reported that circulating levels of IgG antibodies against p16, CD25 and FOXP3 proteins were significantly changed in patients with lung cancer, breast cancer and esophageal cancer. However, different peptide fragments appear to trigger different immune responses. This work aimed to analyze the alteration of plasma IgG for p16-derived peptide antigen called p16a, CD25-derived peptide antigen called CD25a and a FOXP3-derived antigen in hepatocellular carcinoma (HCC). Patients and methods An enzyme-linked immunosorbent assay (ELISA) was developed in-house to detect plasma IgG to p16a, CD25a and FOXP3 in 119 patients with HCC and 132 control subjects. Results Circulating levels of IgG antibodies for all three peptide antigens were significantly higher in HCC patients than control subjects (P<0.001 for all 3 assays); male patients mainly contributed to increase (P<0.01 for all 3 assays). Further analysis showed that plasma anti-p16a, anti-CD25a and anti-FOXP3 IgG levels were increased mainly in patients with intermediate and late-stage HCC (P<0.01 for both assays). Receiver operating characteristic (ROC) curve analysis showed that with a specificity of >95%, the area under the ROC curve (AUC) was 0.62 with 11.4% sensitivity for anti-p16a assay, 0.68 with 14.3% sensitivity for anti-CD25a IgG assay and 0.64 with 10.1% sensitivity for anti-FOXP3 assay. Of the three groups of HCC patients, group 3 (BCLC stage C+D) showed the best sensitivity for the detection of plasma anti-p16a and anti-FOXP3 IgG levels with an AUC of 0.66 and 0.65. Conclusion Circulating IgG antibody to p16a, CD25a and FOXP3 proteins may be a useful biomarker for assessment of HCC prognosis of this malignancy, especially in male patients with HCC.

Abstract
Multiplexed tissue imaging enables precise, spatially resolved enumeration and characterization of cell types and states in human resection specimens. A growing number of methods applicable to formalin-fixed, paraffin-embedded (FFPE) tissue sections have been described, the majority of which rely on antibodies for antigen detection and mapping. This protocol provides step-by-step procedures for confirming the selectivity and specificity of antibodies used in fluorescence-based tissue imaging and for the construction and validation of antibody panels. Although the protocol is implemented using tissue-based cyclic immunofluorescence (t-CyCIF) as an imaging platform, these antibody-testing methods are broadly applicable. We demonstrate assembly of a 16-antibody panel for enumerating and localizing T cells and B cells, macrophages, and cells expressing immune checkpoint regulators. The protocol is accessible to individuals with experience in microscopy and immunofluorescence; some experience in computation is required for data analysis. A typical 30-antibody dataset for 20 FFPE slides can be generated within 2 weeks.

Abstract
Functional, tumor-specific CD8+ cytotoxic T lymphocytes drive the adaptive immune response to cancer. Thus, induction of their activity is the ultimate aim of all immunotherapies. Success of anti-tumor immunotherapy is precluded by marked immunosuppression in the tumor microenvironment (TME) leading to CD8+ effector T cell dysfunction. Among the many facets of CD8+ T cell dysfunction that have been recognized—tolerance, anergy, exhaustion, and senescence—CD8+ T cell senescence is incompletely understood. Naïve CD8+ T cells require three essential signals for activation, differentiation, and survival through T-cell receptor, costimulatory receptors, and cytokine receptors. Downregulation of costimulatory molecule CD28 is a hallmark of senescent T cells and increased CD8+CD28− senescent populations with heterogeneous roles have been observed in multiple solid and hematogenous tumors. T cell senescence can be induced by several factors including aging, telomere damage, tumor-associated stress, and regulatory T (Treg) cells. Tumor-induced T cell senescence is yet another mechanism that enables tumor cell resistance to immunotherapy. In this paper, we provide a comprehensive overview of CD8+CD28− senescent T cell population, their origin, their function in immunology and pathologic conditions, including TME and their implication for immunotherapy. Further characterization and investigation into this subset of CD8+ T cells could improve the efficacy of future anti-tumor immunotherapy.

Abstract
Interventional oncology is a subspecialty field of interventional radiology that addresses the diagnosis and treatment of cancer and cancer-related problems by using targeted minimally invasive procedures performed with image guidance. Immuno-oncology is an innovative area of cancer research and practice that seeks to help the patient's own immune system fight cancer. Both interventional oncology and immuno-oncology can potentially play a pivotal role in cancer management plans when used alongside medical, surgical, and radiation oncology in the care of cancer patients.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and the second most common cause of cancer death worldwide. Current treatment options for patients with intermediate and advanced HCC are limited, and there is an unmet need for novel therapeutic approaches. HCC is an attractive target for immunomodulation therapy, since it arises in an inflammatory milieu due to hepatitis B and C infections and cirrhosis. However, a major barrier to the development and success of immunotherapy in patients with HCC is the liver's inherent immunosuppressive function. Recent advances in the field of cancer immunology allowed further characterization of immune cell subsets and function, and created new opportunities for therapeutic modulation of the immune system. In this review, we present the different immune cell subsets involved in potential immune modulation of HCC, discuss their function and clinical relevance, review the variety of immune therapeutic agents currently under investigation in clinical trials, and outline future research directions.

Abstract
Regulatory T cells (Treg) suppress immune responses in patients with cancer. Surgery is the most effective therapeutic strategy for ovarian cancer (OC). However, the interplay between the Treg population and surgical resection remains unclear. 61 patients with OC who received no prior treatment were enrolled in the study. Treg percentages were characterized from peripheral blood mononuclear cells. We investigated CD4+CD25+, CD4+CD25+Foxp3+, CD8+CD28-, and CD8+Foxp3+ Tregs in OC patients and their postoperative changes using flow cytometry. Treg percentages were significantly higher in OC patients than those in benign ovarian tumors (BOT) and healthy controls. Higher percentages of Tregs were found in patients with stage III/IV than stage I/II OC. Treg percentages were significantly decreased postoperatively. The postoperative Treg percentages in patients with stage I/II OC were similar to those in BOT patients, while postoperative Treg percentages in patients with stage III/IV OC remained higher. Tregs were markedly lower on postoperative day (POD) 3 than preoperatively. They increased slightly after 7days, but remained lower than preoperative levels. These data suggested that Tregs continued to decline from POD 7 to POD 30. Treg percentages are correlated with the tumor burden and could be a key factor in monitoring the immunological status of patients with OC.

Abstract
The mechanisms by which tumor-responsive CD8+ T cells are regulated are important for understanding the tumor immunity and for developing new therapeutic strategies. In current study, we identified the expression of 1810011o10 Rik, which is the homolog of human thyroid cancer 1, in intratumoral activated CD8+ T cells in a murine hepatocellular carcinoma (HCC) implantation model. To investigate the role of 1810011o10 Rik in the regulation of antitumor activity of CD8+ T cells, normal CD8+ T cells were transduced with 1810011o10 Rik-expressing lentiviruses. Although 1810011o10 Rik overexpression did not influence agonistic antibody-induced CD8+ T cell activation in vitro, it inhibited the cytotoxic efficacy of CD8+ T cells on HCC cells in vivo. 1810011o10 Rik overexpression impeded CD8+ T cell-mediated HCC cell apoptosis and favored tumor cell growth in vivo. Further investigation revealed that 1810011o10 Rik blocked the nuclear translocation of Notch2 intracellular domain, which is crucial for CD8+ T cell activity. Furthermore, a brief in vitro experiment suggested that both antigen-presenting cells and TGF-β might be necessary for the upregulation of Rik expression in activated CD8+ T cells. In general, our study disclosed a novel mechanism underlying the negative regulation of antitumor CD8+ T cells during HCC progression.

Abstract
OBJECTIVES The aim of this study was to investigate a possible mechanism of CD8+ regulatory T-cell (Treg) production in an ovarian cancer (OC) microenvironment. MATERIALS AND METHODS Agilent microarray was used to detect changes in gene expression between CD8+ T cells cultured with and without the SKOV3 ovarian adenocarcinoma cell line. QRT-PCR was performed to determine glycolysis gene expression in CD8+ T cells from a transwell culturing system and OC patients. We also detected protein levels of glycolysis-related genes using Western blot analysis. RESULTS Comparing gene expression profiles revealed significant differences in expression levels of 1420 genes, of which 246 were up-regulated and 1174 were down-regulated. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analysis indicated that biological processes altered in CD8+ Treg are particularly associated with energy metabolism. CD8+ Treg cells induced by co-culture with SKOV3 had lower glycolysis gene expression compared to CD8+ T cells cultured alone. Glycolysis gene expression was also decreased in the CD8+ T cells of OC patients. CONCLUSIONS These findings provide a comprehensive bioinformatics analysis of DEGs in CD8+ T cells cultured with and without SKOV3 and suggests that metabolic processes may be a possible mechanism for CD8+ Treg induction.

Abstract
The cJun NH2-terminal kinase (JNK) signaling pathway is required for the development of hepatitis and hepatocellular carcinoma. A role for JNK in liver parenchymal cells has been proposed, but more recent studies have implicated non-parenchymal liver cells as the relevant site of JNK signaling. Here, we tested the hypothesis that myeloid cells mediate this function of JNK. We show that mice with myeloid cell-specific JNK deficiency exhibit reduced hepatic inflammation and suppression of both hepatitis and hepatocellular carcinoma. These data identify myeloid cells as a site of pro-inflammatory signaling by JNK that can promote liver pathology. Targeting myeloid cells with a drug that inhibits JNK may therefore provide therapeutic benefit for the treatment of inflammation-related liver disease.

Abstract
The anatomical architecture of the human liver and the diversity of its immune components endow the liver with its physiological function of immune competence. Adaptive immunity is a major arm of the immune system that is organized in a highly specialized and systematic manner, thus providing long-lasting protection with immunological memory. Adaptive immunity consists of humoral immunity and cellular immunity. Cellular immunity is known to have a crucial role in controlling infection, cancer and autoimmune disorders in the liver. In this article, we will focus on hepatic virus infections, hepatocellular carcinoma and autoimmune disorders as examples to illustrate the current understanding of the contribution of T cells to cellular immunity in these maladies. Cellular immune suppression is primarily responsible for chronic viral infections and cancer. However, an uncontrolled auto-reactive immune response accounts for autoimmunity. Consequently, these immune abnormalities are ascribed to the quantitative and functional changes in adaptive immune cells and their subsets, innate immunocytes, chemokines, cytokines and various surface receptors on immune cells. A greater understanding of the complex orchestration of the hepatic adaptive immune regulators during homeostasis and immune competence are much needed to identify relevant targets for clinical intervention to treat immunological disorders in the liver.

Abstract
Hepatocellular carcinoma (HCC) is a frequent cancer with a high mortality. For early stage cancer there are potentially curative treatments including local ablation, resection and liver transplantation. However, for more advanced stage disease, there is no optimal treatment available. Even in the case of a "curative" treatment, recurrence or development of a new cancer in the precancerous liver is common. Thus, there is an urgent need for novel and effective (adjuvant) therapies to treat HCC and to prevent recurrence after local treatment in patients with HCC. The unique immune response in the liver favors tolerance, which remains a genuine challenge for conventional immunotherapy in patients with HCC. However, even in this "immunotolerant" organ, spontaneous immune responses against tumor antigens have been detected, although they are insufficient to achieve significant tumor death. Local ablation therapy leads to immunogenic tumor cell death by inducing the release of massive amounts of antigens, which enhances spontaneous immune response. New immune therapies such as dendritic cell vaccination and immune checkpoint inhibition are under investigation. Immunotherapy for cancer has made huge progress in the last few years and clinical trials examining the use of immunotherapy to treat hepatocellular carcinoma have shown some success. In this review, we discuss the current status of and offer some perspectives on immunotherapy for hepatocellular carcinoma, which could change disease progression in the near future.

Abstract
The present study aimed to investigate changes in cellular immune function and regulatory T cells (Tregs) in patients with hepatocellular carcinoma (HCC) prior to and following transcatheter arterial chemoembolization (TACE) and their clinical significance. The proportion of CD4+ and CD8+ T cells and Tregs in the peripheral blood between healthy volunteers and patients with HCC were detected by flow cytometry prior to (1 day) and one month following TACE. The level of interleukin (IL)‑35 in the peripheral blood was examined by ELISA. In the peripheral blood of patients with HCC, the proportion of CD4+ T cells in the total T lymphocytes was significantly lower compared with that of healthy volunteers (26.71 ± 5.57, vs. 34.74 ± 2.86%; P<0.05) and the ratio of CD4+/CD8+ T lymphocytes in patients with HCC was lower compared with that of healthy adults prior to TACE (1.03 ± 0.14, vs. 1.68 ± 0.16, P<0.05). The ratio markedly increased following TACE treatment (30.52 ± 4.19, vs. 1.29 ± 0.14). The percentage of CD4+CD25+ Treg cells in the total CD4+ T cells isolated from the patients with HCC was markedly higher compared with that of healthy adults prior to TACE (11.12 ± 3.58%, vs. 4.98 ± 1.45%, P<0.05) and it was significantly decreased following TACE (7.58±2.65%; P<0.05). No statistically significant difference in the expression of IL‑35 was detected prior to or following TACE in patients with HCC and healthy adults (369.66 ± 95.53, 352.28 ± 107.50 and 316.24 ± 89.21 pg/ml, respectively). The level of AFP, an oncofetal protein of ~72 kDa, which is produced by normal gastrointestinal cells, yolk sac cells and fetal hepatocytes immediately following birth, was increased in patients with HCC (1674 ± 1649 ng/ml) and was significantly decreased following TACE (827 ± 981 ng/ml). Treg cells changed in positive correlation with the change of AFP, with a correlation coefficient of 0.401. TACE markedly improved the immune function of patients with HCC.

[PMID: 26074703 PMCID: PMC4458775 DOI: 10.3748/wjg.v21.i21.6649] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2014] [Revised: 12/30/2014] [Accepted: 01/16/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate whether neuron-glial antigen 2 (NG2) could be an effective prognostic marker in hepatocellular carcinoma (HCC).
METHODS: NG2 expression was semi-quantitatively scored from the immunohistochemistry (IHC) data based on the number of positive cells and the staining intensity. A total of 132 HCC specimens and 96 adjacent noncancerous tissue samples were analyzed by IHC for NG2 protein expression. To confirm the NG2 expression levels observed by IHC, we measured NG2 expression in 30 randomly selected tumor and adjacent noncancerous tissue samples by quantitative real-time polymerase chain reaction and Western blot. The correlations between NG2 protein expression and the clinicopathological features of HCC patients were analyzed using the χ2 test. To assess the prognostic value of NG2 for HCC, the association between NG2 expression and survival was analyzed using the Kaplan-Meier method with the log-rank test. To further evaluate the prognostic value of NG2 expression, a Cox multivariate proportional hazards regression analysis was performed with all the variables to derive risk estimates related to disease-free and overall survival and to control for confounders.
RESULTS: High NG2 expression was observed in significantly more primary tumor samples (63.6%; 84/132) compared with the adjacent noncancerous tissue samples (28.1%; 27/96) (P < 0.0001). Moreover, high NG2 protein expression was closely associated with tumor differentiation (χ2 = 9.436, P = 0.0089), recurrence (χ2 = 5.769, P = 0.0163), tumor-node-metastasis (TNM) stage (χ2 = 8.976, P = 0.0027), and invasion (χ2 = 5.476, P = 0.0193). However, no significant relationship was observed between NG2 protein expression in HCC and other parameters, such as age, sex, tumor size, serum alpha fetoprotein (AFP), tumor number, or tumor capsule. The log-rank test indicated a significant difference in the overall survival of HCC patients with high NG2 expression compared with those with low NG2 expression (29.2% vs 9.5%, P < 0.001). Moreover, NG2 expression in HCC tissue significantly correlated with disease-free survival (15.2% vs 6.7%, P < 0.001). Multivariate analysis showed that NG2 expression (HR = 2.035, P = 0.002), serum AFP (HR = 1.903, P = 0.003), TNM stage (HR = 2.039, P = 0.001), and portal vein invasion (HR = 1.938, P = 0.002) were independent prognostic indicators for OS in HCC patients. Furthermore, NG2 expression (HR = 1.974, P = 0.003), serum AFP (HR = 1.767, P = 0.008), TNM stage (HR = 2.078, P = 0.001), tumor capsule (HR = 0.652, P = 0.045), and portal vein invasion (HR = 1.941, P = 0.002) were independent prognostic indicators for DFS in HCC patients.
CONCLUSION: The up-regulation of NG2 is associated with poor prognosis in HCC. Therefore, NG2 could be useful as an additional prognostic marker to increase the resolution of traditional approaches.

Abstract
AIM: To assess the prognostic significance of immunological and nutritional-based indices, including the prognostic nutritional index (PNI), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio in gastric cancer.
METHODS: We retrospectively reviewed 632 gastric cancer patients who underwent gastrectomy between 1998 and 2008. Areas under the receiver operating characteristic curve were calculated to compare the predictive ability of the indices, together with estimating the sensitivity, specificity and agreement rate. Univariate and multivariate analyses were performed to identify risk factors for overall survival (OS). Propensity score analysis was performed to adjust variables to control for selection bias.
RESULTS: Each index could predict OS in gastric cancer patients in univariate analysis, but only PNI had independent prognostic significance in multivariate analysis before and after adjustment with propensity scoring (hazard ratio, 1.668; 95% confidence interval: 1.368-2.035). In subgroup analysis, a low PNI predicted a significantly shorter OS in patients with stage II-III disease (P = 0.019, P < 0.001), T3-T4 tumors (P < 0.001), or lymph node metastasis (P < 0.001). Canton score, a combination of PNI, NLR, and platelet, was a better indicator for OS than PNI, with the largest area under the curve for 12-, 36-, 60-mo OS and overall OS (P = 0.022, P = 0.030, P < 0.001, and P = 0.024, respectively). The maximum sensitivity, specificity, and agreement rate of Canton score for predicting prognosis were 84.6%, 34.9%, and 70.1%, respectively.
CONCLUSION: PNI is an independent prognostic factor for OS in gastric cancer. Canton score can be a novel preoperative prognostic index in gastric cancer.

Abstract
Given its tumor-specific expression, including liver cancer, OY-TES-1 is a potential molecular marker for the diagnosis and immunotherapy of liver cancers. However, investigations of the mechanisms and the role of OY-TES-1 in liver cancer are rare. In the present study, based on a comprehensive bioinformatic analysis combined with RNA interference (RNAi) and oligonucleotide microarray, we report for the first time that downregulation of OY-TES-1 resulted in significant changes in expression of NANOG, CD9, CCND2 and CDCA3 in the liver cancer cell line BEL-7404. NANOG, CD9, CCND2 and CDCA3 may be involved in cell proliferation, migration, invasion and apoptosis, yet also may be functionally related to each other and OY-TES-1. Among these molecules, we identified that NANOG, containing a Kazal-2 binding motif and homeobox, may be the most likely candidate protein interacting with OY-TES-1 in liver cancer. Thus, the present study may provide important information for further investigation of the roles of OY-TES-1 in liver cancer.

Abstract
AIMS Dysfunction of the host immune system in cancer patients can be due to a number of factors, including lymphocyte apoptosis. Several studies showed that Foxp3+T cells take part in inducing this process by expressing FasL in tumor patients. However, the relationship between apoptosis, CD8+T cells and Foxp3+T cells in HCC patients is still unclear. The present study was designed to investigate the correlation between apoptosis levels and Fas/FasL expression in CD8+T lymphocytes and Foxp3+T cells in patients with HCC. METHODS CD8+T cells and CD3+Foxp3+T cells were tested from peripheral blood of HCC patients and normal controls and subjected to multicolor flow cytometry. The expression of an apoptosis marker (annexin V) and the death receptor Fas in CD8+T cells and FasL in CD3+Foxp3+T cells were evaluated. Serum TGF-β1 levels in patients with HCC were measured by enzyme-linked immunosorbent assay. The relationship between apoptosis and Fas expression, as well as FasL expression in CD3+Foxp3+T cells was then evaluated. RESULTS The frequency of CD8+T cells binding annexin V and Fas expression in CD8+T cells, were all higher in HCC patients than normal controls and the proportion of apoptotic CD8+T cells correlated with their Fas expression. Serum TGF-β1 levels correlated inversely with CD3+Foxp3+T cells. CONCLUSIONS Fas/FasL interactions might lead to excessive turnover of CD8+T cells and reduce anti-tumor immune responses in patients with HCC. Further investigations of apoptosis induction in Fas+CD8+T cells in vitro are required.

Abstract
Introduction IL-10--producing B cells, Foxp3-expressing T cells (Tregs) and the IDO-expressing dendritic cells (pDC) are able to modulate inflammatory processes, to induce immunological tolerance and, in turn, to inhibit the pathogenesis of autoimmune disease. The aim of the study was to characterize and to enumerate peripheral IL-10--producing B cells, Tregs and pDCregs in primary Sjögren's Syndrome (pSS) patients in regard of their clinical and serologic activity. Methods Fifty pSS patients and 25 healthy individuals were included in the study. CD19+--expressing peripheral B lymphocytes were purified by positive selection. CD19+/CD24hi/CD38hi/IL-10--producing B cells, CD4+/CD25hi/Foxp3+ and CD8+/CD28-/Foxp3+ Tregs, as well as CCR6+/CD123+/IDO+ DCs, were quantitated by flow cytometry. Results Immature/transitional circulating IgA+ IL-10--producing B cells had higher levels in pSS patients versus control group, whereas CD19+/CD38hi/IgG+/IL-10+ cells had lower percentage versus control. Indeed CD19+/CD24hi/CD38hi/CD5+/IL-10+, CD19+/CD24hi/CD38hi/CD10+/IL-10+, CD19+/CD24hi/CD38hi/CD20+/IL-10+, CD19+/CD24hi/CD38hi/CD27-/IL-10+, and CD19+/CD24hi/CD38hi/CXCR7+/IL-10+ cells had higher frequency in clinical inactive pSS patients when compared with control group. Remarkably, only percentages of CD19+/CD24hi/CD38hi/CD10+/IL-10+ and CD19+/CD24hi/CD38hi/CD27-/IL-10+ subsets were increased in pSS serologic inactive versus control group (P < 0.05). The percentage of IDO-expressing pDC cells was higher in pSS patients regardless of their clinical or serologic activity. There were no statistically significant differences in the percentage of CD4+/CD25hi/Foxp3+ Tregs between patient groups versus controls. Nonetheless, a decrease in the frequency of CD8+/CD28-/Foxp3+ Tregs was found in inactive pSS patients versus controls (P < 0.05). Conclusions The findings of this exploratory study show that clinical inactive pSS patients have an increased frequency of IL-10--producing B cells and IDO-expressing pDC cells.

Abstract
Merkel cell carcinomas (MCCs) are rare but highly malignant skin cancers associated with a recently described polyomavirus. MCC tumors were infiltrated by T cells, including effector, central memory, and regulatory T cells. Infiltrating T cells showed markedly reduced activation as evidenced by reduced expression of CD69 and CD25. Treatment of MCC tumors in vitro with IL-2 and IL-15 led to T-cell activation, proliferation, enhanced cytokine production, and loss of viable tumor cells from cultures. Expanded tumor-infiltrating lymphocytes showed TCR repertoire skewing and upregulation of CD137. MCC tumors implanted into immunodeficient mice failed to grow unless human T cells in the tumor grafts were depleted with denileukin diftitox, suggesting that tumor-specific T cells capable of controlling tumor growth were present in MCC. Both CD4(+) and CD8(+) FOXP3(+) regulatory T cells were frequent in MCC. Fifty percent of nonactivated T cells in MCC-expressed PD-1, a marker of T-cell exhaustion, and PD-L1 and PD-L2 were expressed by a subset of tumor dendritic cells and macrophages. In summary, we observed tumor-specific T cells with suppressed activity in MCC tumors. Agents that stimulate T-cell activity, block regulatory T cell function, or inhibit PD-1 signaling may be effective in the treatment of this highly malignant skin cancer.

Hepatitis B surface antigen could contribute to the immunopathogenesis of hepatitis B virus infection. ISRN GASTROENTEROLOGY 2013; 2013:935295.

Abstract
Various findings concerning the clinical significance of quantitative changes in hepatitis B surface antigen (HBsAg) during the acute and chronic phase of hepatitis B virus (HBV) infection have been reported. In addition to being a biomarker of HBV-replication activity, it has been reported that HBsAg could contribute to the immunopathogenesis of HBV persistent infection. Moreover, HBsAg could become an attractive target for immune therapy, since the cellular and humeral immune response against HBsAg might be able to control the HBV replication and life cycle. However, several reports have described the immune suppressive function of HBsAg. HBsAg might suppress monocytes, dendritic cells (DCs), natural killer (NK), and natural killer T (NK-T) cells by direct interaction. On the other hand, cytotoxic T lymphocytes (CTLs) and helper T (Th) cells were exhausted by high amounts of HBsAg. In this paper, we focused on the immunological aspects of HBsAg, since better understanding of the interaction between HBsAg and immune cells could contribute to the development of an immune therapy as well as a biomarker of the state of HBV persistent infection.

Abstract
Tumor-infiltrating immune cells have long been thought to affect tumor growth. In recent years, large retrospective studies have shown that the nature and polarization of the immune cells found within the tumor microenvironment impact not only the growth of the primary tumor, but also disease progression and patient survival. This has triggered considerable interest for an in depth analysis of the tumoral immune microenvironment and has created a need for standardized methods to characterize tumor-infiltrating immune cells. Here, we describe three approaches that can be used in mouse and human melanoma tumors.

Abstract
Difficulty in segregating graft-versus-tumor effect (GvT) from graft-versus-host disease (GvHD) remains a major limitation of allogeneic stem cell transplantation (Allo SCT). Naturally occurring regulatory T cells have been suggested to suppress alloreactive T cells involved in GvHD; however, their non-selective suppressive effect raises concern regarding probable attenuation of the GvT effect. Recent studies suggested inducible CD8 (iCD8) cells to be useful in suppressing autoimmune reactions, although their function in the Allo SCT setting has not been fully explored. The current study assessed in-vitro the properties of iCD8 T cells, generated in response to allogeneic dendritic cells (DCs), imitating the Allo SCT conditions. CD25(-) peripheral blood mononuclear cells (PBMCs) were stimulated with allogeneic DCs in mixed lymphocyte culture (MLC). The resultant iCD8(+)CD25(+) population was isolated and assessed for phenotypic markers, cytokine expression profile, cell proliferation, inhibitory capacity and anti-viral response. The generated CD8(+)CD25(+)FOXP3(+) T cells selectively inhibited the primary allogeneic response, without attenuating T cell response against other stimuli, such as mitogens or a cytomegalovirus (CMV) recall antigen. In conclusion, iCD8(+)CD25(+) cells suppress allogeneic stimulation, while maintaining the capacity to respond to infectious pathogens. These cells could be potentially efficient in the Allo SCT setting, where GvHD prevention is required.

Abstract
Regulatory Foxp3-expressing T cells (Tregs), IL-10-producing B cells (Bregs), and IDO-expressing dendritic cells (DCregs) downregulate inflammatory processes and induces peripheral tolerance. These subpopulations also might participate in maintaining allograft immunological quiescence in kidney transplant recipients (KTRs) with an excellent long-term graft function under immunosuppression (ELTGF). The aim of the study was to characterize and to enumerate peripheral Tregs, Bregs, and DCregs in KTR with an ELTGF for more than 5 years after transplant. Fourteen KTR with an ELTGF, 9 KTR with chronic graft dysfunction (CGD), and 12 healthy donors (HDs) were included in the study. CD19+-expressing peripheral B lymphocytes were purified by positive selection. IL-10-producing B cells, CD4+/CD25hi, and CD8+/CD28− Tregs, as well as CCR6+/CD123+/IDO+ DCs, were quantitated by flow cytometry. IL-10-producing Bregs (immature/transitional, but not CD19+/CD38hi/CD24hi/CD27+B10 cells), CCR6+/CD123+/IDO+ DCs, and Tregs from ELTGF patients had similar or higher percentages versus HD (P < 0.05). By contrast, number of Tregs, DCregs, and Bregs except for CD27+B10 cells from CGD patients had lower levels versus HD and ELTGF patients (P < 0.05). The findings of this exploratory study might suggest that in ELTGF patients, peripheral tolerance mechanisms could be directly involved in the maintenance of a quiescent immunologic state and graft function stability.

Abstract
The role of Foxp3-positive regulatory T cells (Foxp3 Tregs) in suppression of antitumoral immune response is well documented in patients with cancer. However, it is not known whether Foxp3 Tregs are associated with specific clinicopathologic characteristics of hepatocellular carcinoma (HCC). The aims of the present study were: (1) to investigate the relationship between Foxp3 Tregs and histologic differentiation, Edmondson-Steiner (ES) nuclear grade, vascular invasion, and pathologic stage of HCC in patients undergoing surgery for their disease; and (2) to evaluate any Foxp3 Treg-defined difference in the risk for tumor recurrence or death. The study sample included 131 histologic sections of HCC. The number of tumor-infiltrating CD3, CD8, and Foxp3 lymphocytes was assessed by immunohistochemistry. An increased Foxp3:CD3 ratio was associated with more poorly differentiated HCC (P=0.0016) and higher ES nuclear grade (P=0.0407). An increased Foxp3:CD8 ratio was also associated with poorer differentiation (P=0.0044), higher ES nuclear grade (P=0.0179), recurrence (P=0.0183), decreased overall survival (hazard ratio=1.153; 95% confidence interval, 1.019-1.304; P=0.0235), and decreased disease-free survival (hazard ratio=1.138; 95% confidence interval, 1.016-1.273; P=0.0249). Tumor size and type of surgery (surgical resection) were associated with decreased disease-free survival on univariate analysis but not on multivariate analysis. In conclusion, a higher concentration of tumor-infiltrating Foxp3 Tregs in HCC is associated with higher grade and poorly differentiated tumors and signifies an unfavorable prognosis.

Abstract
Several bone marrow-derived cells have been shown to promote tumour growth and progression. These cells can home to the primary tumour and become active components of the tumour microenvironment. Recent studies have also identified bone marrow-derived cells—such as mesenchymal stem cells and regulatory T cells—as contributors to cancer metastasis. The innate versatility of these cells provides diverse functional aid to promote malignancy, ranging from structural support to signal-mediated suppression of the host immune response. Here, we review the role of mesenchymal stem cells and regulatory T cells in cancer metastasis. A better understanding of the bipolar nature of these bone marrow-derived cells in physiological and malignant contexts could pave the way for new therapeutics against metastatic disease.

An inflammation-based prognostic index predicts survival advantage after transarterial chemoembolization in hepatocellular carcinoma. Transl Res 2012; 160:146-52.

Abstract
Transarterial chemoembolization (TACE) is the preferred treatment for unresectable, intermediate-stage hepatocellular carcinoma (HCC). However, survival after TACE can be highly variable, suggesting the need for more accurate patient selection to improve therapeutic outcome. We have explored the prognostic ability of the blood neutrophil-to-lymphocyte ratio (NLR), a biomarker of systemic inflammation, as a predictor of survival after TACE. Fifty-four patients with a diagnosis of HCC eligible for TACE were selected. Clinicopathologic variables were collected, including demographics, tumor staging, liver functional reserve, and laboratory variables. Dynamic changes in the NLR before and after TACE were studied as predictors of survival using both a univariate and multivariate Cox regression model. Patients in whom the NLR remained stable or normalized after TACE showed a significant improvement in overall survival of 26 months compared with patients showing a persistently abnormal index (P = 0.006). Other predictors of survival on univariate analysis were Cancer of the Liver Italian Program score (P = 0.05), intrahepatic spread (P = 0.01), tumor diameter > 5 cm (P = 0.02), > 1 TACE (P = 0.01), alpha-fetoprotein ≥ 400 (P = 0.002), and radiologic response to TACE (P < 0.001). Improved NLR after TACE (P = 0.03) and radiologic response after TACE (P = 0.003) remained independent predictors of survival on multivariate analysis. Changes in alpha-fetoprotein after treatment did not predict survival. Patients with a persistently increased NLR have a worse outcome after TACE. NLR is a simple and universally available stratifying biomarker that can help identify patients with a significant survival advantage after TACE.

Abstract
Background: There is increasing evidence that the presence of an ongoing systemic inflammatory response is a stage-independent predictor of poor outcome in patients with cancer. The aim of this study was to investigate whether an inflammation-based prognostic score, the prognostic nutritional index (PNI), is associated with overall survival (OS) in patients with hepatocellular carcinoma (HCC). Methods: All patients with a new diagnosis of HCC presenting to the Medical Oncology Department, Hammersmith Hospital between 1993 and 2011 (n=112) were included. Demographic and clinical data were collected. Patients in whom the combined albumin (g l−1) × total lymphocyte count × 109 l−1 was ⩾45, at presentation, were allocated a PNI score of 0. Patients in whom this total score was <45 were allocated a score of 1. Univariate and multivariate analyses were performed to identify clinicopathological variables associated with OS. Independent predictors of survival identified on multivariate analysis were validated in an independent, stage-matched cohort of 68 patients. Results: Univariate analyses showed that PNI (P=0.003), intrahepatic spread (P<0.001), the presence of extrahepatic disease (P=0.006), portal vein thrombosis (P=0.02), tumour multifocality (P=0.003), alfa-fetoprotein >400 ng ml−1 (P<0.001) and Barcelona Clinic Liver Cancer score (P<0.01) were all predictors of OS in the training set. Multivariate analysis revealed the PNI (P=0.05), presence of extrahepatic disease (P<0.001) and degree of intrahepatic spread (P<0.001) as independent predictors of worse OS in this population. The PNI retained independent prognostic value in the validation set (P<0.001). Conclusion: The presence of a systemic inflammatory response, as measured by the PNI, is an independent and externally validated predictor of poor OS in patients with HCC.

Abstract
INTRODUCTION The degree of activation of cells involved in cellular immune response against tumor antigens (cytotoxic lymphocytes Tc) as well as efficiency of the mechanisms which promote immunosuppression (Treg - regulatory cells CD4(+)CD25(+)Foxp3(+)) may determine the course of the neoplastic disease. The aim of this study was to assess the function of autologous peripheral blood mononuclear cells (PBMCs) involved in the immunological processes on the basis of expression of Foxp3 and RORgamma t molecules as well as analysis of the relationships with clinical and morphological features of the tumor (pT and pN stage, G feature, degree of invasiveness according to the TFG classification) in laryngeal carcinoma. MATERIAL AND METHODS The analysis included a group of 59 patients with verified squamous cell carcinoma of the larynx. In the pathologic evaluation pTNM classification criteria, depth of invasion and degree of histological differentiation were used. Expression levels of mRNA for Foxp3 and RORgamma t in peripheral blood mononuclear cells by quantitative analysis of the amplified product in real time (real-time RT(2)-PCR) were evaluated. The level of Foxp3 and RORgamma t protein expression by Western blot analysis was determined. RESULTS In squamous cell carcinomas of the larynx, with the highest tumor aggressiveness the significantly highest level of mRNA and protein expression for Foxp3 molecule were observed. The severity of Foxp3 expression at both gene and protein level were positively linearly correlated with the degree of local extent of the tumor (pT3-4), depth of invasion (invasion of cartilage) and the degree of histological differentiation (low-differentiated tumors G3). In the study group of laryngeal cancers significantly lower level of RORgamma t expression in carcinomas with less invasive changes (pT1-2, high-differentiated tumors G1, carcinomas with microinvasion without evidence of invasion beyond the lamina propria) was also noted. CONCLUSIONS The study results indicate the important role of immune cell activity as indicators of advancement of clinical and morphological changes in squamous cell carcinoma of the larynx.
