Identification of a Gene Signature Closely Related to Immunosuppressive Tumour Microenvironment Predicting Prognosis of Patients in EGFR Mutant Lung Adenocarcinoma. Front Oncol 2021; 11:732841. [PMID: 34631565 PMCID: PMC8498106 DOI: 10.3389/fonc.2021.732841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 09/07/2021] [Indexed: 11/13/2022] Open
Abstract
Lung adenocarcinomas (LUADs) harbouring epidermal growth factor receptor (EGFR) mutations are generally unable to benefit from immune checkpoint inhibitors (ICIs) due to an immunosuppressive tumour microenvironment (TME) and a lower tumour mutation burden. Currently, no gene signature can comprehensively evaluate the TME and predict the prognosis of patients with EGFR-mutant LUAD. Using the Cancer Genome Atlas database of EGFR-mutant LUAD based on the immune score derived from the ESTIMATE algorithm, we divided 80 patients with EGFR-mutant LUAD samples into high and low immune score groups with different immune microenvironments. Subsequently, we screened 396 differentially expressed immune-related genes with prognostic value. The top Gene Ontology terms were significantly enriched in biological functions related to T cell differentiation, immune response, cell cycle, and cell proliferation, which are closely related to the immune microenvironment of tumours. In addition, the KEGG pathway enrichment analysis mainly focused on cell cycle, cell adhesion molecules, and cytokine-cytokine receptor interaction, which also had a relationship with the immune response. Subsequently, we identified a three-gene signature including BTLA, BUB1B, and CENPE using the LASSO Cox regression model. The three-gene signature could accurately identify patients at risk of EGFR-mutant LUAD in the training and validation sets and high-risk patients from both the sets exhibited significantly shorter overall survival (p=0.0053 and p=0.035, respectively). CIBERSORT was used to evaluate the abundance of immune cell infiltration in the EGFR-mutant LUAD microenvironment. The immune activity of B cells and macrophages was higher in the low-risk group, while the immune activity of natural killer cells and T cells was higher in the high-risk group. Thus, the three-gene signature closely related to immunosuppressive TME could predict the risk and prognosis in patients with EGFR-mutant LUAD.

Abstract
B and T lymphocyte attenuator (BTLA) is an immune-inhibitory receptor that negatively regulates the lymphocyte activation. A few studies have been devoted to the relationship between BTLA gene variations and cancer's risk. It has been essentially demonstrated to be involved in increasing cancer risk in chronic lymphocyte leukaemia, renal cell carcinoma, breast and colorectal cancer predispositions in Asian population. The aim of this study was to evaluate the association between BTLA gene polymorphisms and the risk of lung cancer in the Tunisian population. In a case-control study, three BTLA single-nucleotide polymorphism (SNP): rs1982809 (A > G), rs9288952 (G > A) and rs9288953(C > T) were genotyped with the use of TaqMan probes in 169 lung cancer patients and in 300 controls. The rs1982809 SNP was significantly associated with an increased risk of lung cancer compared with controls in codominant and dominant models. The heterozygous rs1982809-AG genotype carriers had a higher risk of developing lung cancer when compared to AA genotype carriers in Tunisian population (OR (95%CI) = 1.63 (1.09-2.42), p = .01]. The AG genotype is an important risk factor associated with lymphatic invasion (OR = 3.71) and large-sized lung tumour (OR = 1.80). It is also a risk factor for the development of an adenocarcinoma subtype (OR = 2.08). However, the BTLA rs9288953 and rs9288952 SNPs were not associated with susceptibility for lung cancer (p > .05). Haplotype comparison did not show any significant association in our research. For the survival analysis, there was no impact of BTLA SNPs on the mortality risk associated to lung cancer in Tunisian patients. The current study is the first to demonstrate an association between BTLA rs1982809 polymorphism and an increased lung cancer risk in the Tunisian population.

Abstract
Indoleamine 2,3-dioxygenase 1 (IDO1), which degrades the essential amino acid tryptophan, exerts immunosuppressive functions and serves a crucial role in multiple types tumor progression, including non-small-cell lung cancer (NSCLC) and melanoma. Recent studies have reported that T-cell exhaustion is increased during tumor progression, which impairs the antitumor immune response. However, the association between IDO1 and T-cell exhaustion during tumor progression remains unknown. The present study evaluated the effect of IDO1 on T-cell exhaustion in lung cancer mice. The present study demonstrated that IDO1 knockdown by small interfering RNA in the LLC cell line inhibited T-cell exhaustion. Furthermore, the role of IDO1 in T-cell exhaustion during lung cancer progression was determined in an in vivo mouse model using IDO1 short hairpin RNA (shRNA). The results demonstrated that inhibition of IDO1 activity by shRNA administration in vivo significantly delayed the onset and growth of tumors. In addition, the expression levels of the inhibitory receptors programmed death-1 (PD-1) and B and T lymphocyte attenuator (BTLA) were increased in T-cells from the lung tumor-bearing mice, whereas interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-α) levels in serum were decreased compared with the control mice. However, no difference in the absolute number of T cells was observed, including CD4+ and CD8+ T cells. In addition, IDO1 knockdown by shRNA inhibited T-cell exhaustion in lung tumor-bearing mice, which was characterized by decreased expression of PD-1 and BTLA on T cells. By contrast, IL-2 and TNF-α levels in serum were increased in IDO1-shRNA-treated mice. By using a shRNA approach, the present study demonstrated that IDO1 activity may be involved in tumor growth, and that IDO1 silencing may inhibit tumor progression by impeding the process of T-cell exhaustion.

Abstract
Background B and T lymphocyte attenuator (BTLA) is a novel immune checkpoint with an unclear role in non–small-cell lung cancer (NSCLC). In contrast, the programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) checkpoint is a potentially curative immunotherapy target in NSCLC. Our study investigated BTLA expression and its relationship with PD-1/PD-L1, tumor-infiltrating lymphocytes (TILs), and clinicopathological features. Methods The protein expressions of BTLA, PD-1, and PD-L1 were evaluated by immunohistochemistry (IHC) and TIL abundance was scored in paraffin-embedded tissues from surgically resected specimens from 87 patients with stage I–III NSCLC. Results BTLA was expressed in tumor cells in 35 patients with NSCLC (40.2%). In addition, 42 patients (48.3%) were positive for PD-1 in TILs and 31 (35.6%) were positive for PD-L1 in tumor cells. BTLA was overexpressed in patients with lymphatic invasion (P=0.045) and an advanced tumor stage (P=0.034). High expression of BTLA was positively correlated with a high level of PD-L1 (P=0.011). Patients with positive BTLA expression had a shorter relapse-free survival (RFS) than those with negative BTLA expression (P=0.029). Moreover, patients negative for both BTLA and PD-L1 had a longer RFS than patients who were positive for BTLA or PD-L1 or for both checkpoints (P=0.012). The same pattern was shown for overall survival (P=0.031). Conclusion High BTLA expression may predict poor prognosis in patients with NSCLC and may represent a new immunotherapy target.

Abstract
Viral vectors represent a potential strategy for the treatment of human malignant tumors. Currently, recombinant adenovirus vectors are commonly used as gene therapy vehicles, as it possesses a proven safety profile in normal human cells. The recombinant adenovirus system has an ability to highly express exogenous genes and increase the stability of the carrier, which is only transiently expressed in the host cell genome, without integrating. Malignant melanoma cells are produced by the skin, and melanocyte tumors that exhibit higher malignant degrees lead to earlier transfer and higher mortality. In the present study, a recombinant adenovirus (rAd) was generated to express Anti-programmed death-1 (rAd-Anti-PD-1) and used to investigate the efficacy in melanoma cells and tumors. The results demonstrated that B16-F10 cell growth was significantly inhibited and the apoptosis incidence rate was markedly promoted following rAd-PD-1 treatment. The present study demonstrated that the production of α and β interferon was increased, which led to the induction of dendritic cell (DCs) maturation in rAd-anti-PD-1-treated mice. The present study indicated that rAd-anti-PD-1 exhibited the ability to generate more cluster of differentiation (CD)4+CD8+ T cells and induce a PD-1-specific cytotoxic T lymphocyte through DC-targeted surface antigens in mice. This resulted in a further enhanced recognition of melanoma cells due to DCs being targeted by the rAd-anti-PD-1-encoded PD-1. Notably, mice treated with the rAd-anti-PD-1-targeted PD-1 demonstrated an improved protection compared with tumor-bearing mice from the challenge group treated with a recombinant gutless adenovirus and Anti-PD-1. In conclusion, the present study demonstrated that targeting the melanoma surface antigens via the rAd-anti-PD-1-infected tumor cells enhanced the ability of recombinant adenovirus to induce a potent tumor-inhibitory effect and antigen-specific immune response.

Abstract
Although the expression of T-cell antigens and proteins associated with tumor-infiltrating T-lymphocytes (TILs), regulatory T cells (T-regs), and B-cell development have been evaluated in classical Hodgkin lymphoma (cHL), few studies correlate these proteins' expression patterns with clinical outcome. The purpose of this study was to evaluate proteins expressed in the Reed-Sternberg cells (RSCs) and TILs of cHLs at initial diagnosis to determine their prognostic significance. The expression of 12 proteins in RSCs and TILs from 88 diagnostic cHL biopsies was quantitated and correlated to overall survival (OS) and progression-free survival (PFS). CD2, CD3, CD4, CD5, CD7, CD25, PD1, TIA1, MUM1, and ZAP70 expression in RSCs did not correlate with OS or PFS, nor did programmed death 1 (PD1) expression in TILs. High numbers of TIA1-positive TILs (≥50%) correlated with OS (P=0.027), but not PFS (P=0.993) in univariate analysis. Expression of CD2, CD3, CD4, CD5, and/or TIA1 (6%) in RSCs was associated with lymphocyte-rich/mixed-cellularity subtype (P=0.032). High International Prognostic Score (IPS; P=0.036), and high stage (P=0.046) were independent predictors of worse PFS in univariate analysis. Low IPS (P=0.003) and nodular sclerosing subtype (P=0.022) were associated with better OS in univariate analysis. Only the IPS predicted OS in multivariate (P=0.009) analysis. High TIA1+ TILs correlated with worse clinical outcomes for cHLs, as did PAX5-RSCs (P=0.024), although only 2/74 cases were shown to be negative for this marker, suggesting that the tumor microenvironment and a transcription factor crucial for B-cell development are critical biological determinants of the disease course.

Abstract
The aim of this study was to determine the association between polymorphisms in gene encoding B- and T-lymphocyte attenuator (BTLA) and susceptibility to chronic lymphocytic leukemia (CLL) and their influence on mRNA expression of BTLA gene in T and B cells from CLL patients (pts.). The following BTLA single-nucleotide polymorphisms (SNPs): rs2705511, rs1982809, rs9288952, rs76844316, rs16859633, rs9288953, rs2705535, rs1844089, rs2705565, rs2633580 were genotyped with use of TaqMan probes in 321 CLL pts. and in 470 controls. The mRNA levels of human BTLA were determined in subpopulations of T and B cells from 37 CLL patients with use of Applied Biosystems assays. Three SNPs: rs1982809, rs2705511 and rs9288953 were associated with susceptibility to CLL. The frequency of rs1982809[G] allele and rs2705511[C] allele carriers was higher in patients compared to the controls (0.51 vs. 0.41, OR 1.51, 95% CI 1.14-2.02, p = 0.004 and 0.56 vs. 0.44, OR 1.62, 95% CI 1.22-2.16, p = 0.0009, respectively). Furthermore, rs9288953[TT] genotype was overrepresented in CLL pts. compared to the controls (0.22 vs. 0.14, OR 1.74, 95% CI 1.20-2.53, p = 0.004). The evaluation of the influence of BTLA SNPs on BTLA mRNA expression in CLL pts. showed that the presence of rs1982809[G] allele was associated with lower median (±SD) BTLA mRNA expression in T cells (expressed as 2-delta Ct) in CLL pts. as compared to [AA] homozygotes (0.009 ± 0.013 vs. 0.026 ± 0.012, p = 0.03). Our results indicate that rs1982809 BTLA gene polymorphism is associated with mRNA expression level and that variations in the BTLA gene might be considered as potentially low-penetrating CLL risk factor.

Abstract
Biomarkers that can serve as diagnostic and prognostic indicators of esophageal squamous cell carcinoma (ESCC) are urgently needed to help improve patient outcomes. Here, the expression of epidermal growth factor receptor (EGFR) and costimulatory molecule B7-H3, both of which have been implicated in tumor onset and progression in certain tumors, was investigated in relation to the clinical characteristics and survival outcomes of patients with ESCC. ESCC tissue samples were analyzed for 100 patients. Tumor and patient characteristics were recorded. Tissues were investigated for EGFR and B7-H3 staining by immunohistochemistry. Patients were followed for up to 96 months to determine overall survival (OS) and progression-free survival (PFS). High expression for EGFR (68.0%) and B7-H3 (66.0%) was observed in the majority of cases. High expression of either EGFR or B7-H3 was correlated with tumor invasion depth and clinical stage (P<0.05). Further, high expression of either EGFR or B7-H3 was correlated with worse survival outcomes. The estimated OS (38.1 months) and PFS (13.4 months) of patients with high expression of EGFR were lower than those of patients with low expression (69.3 and 68.1 months, P<0.05). The estimated OS (31.1 months) and PFS (13.1 months) of patients with high expression of B7-H3 were also lower than those of patients with low expression (69.3 and 66.6 months, P<0.05). Indeed, Cox multiple regression showed that OS and PFS were correlated with EGFR (relative risk =1.853, 1.875, respectively) and B7-H3 (relative risk =1.886, 2.061, respectively) (all P<0.05) expression level. Thus, EGFR and B7-H3 are highly expressed in tumor tissues of patients with ESCC. Their expression levels are correlated with tumor severity and survival, and therefore these may be viable biomarkers to aid in prognosis determination.

Abstract
Manipulation of co-stimulatory or co-inhibitory checkpoint proteins allows for the reversal of tumor-induced T-cell anergy observed in cancer. The field has gained credence given success with CTLA-4 and PD-1 inhibitors. These molecules include immunoglobulin family members and the B7 subfamily as well as the TNF receptor family members. PD-L1 inhibitors and LAG-3 inhibitors have progressed through clinical trials. Other B7 family members have shown promise in preclinical models. TNFR superfamily members have shown variable success in preclinical and clinical studies. As clinical investigation in tumor immunology gains momentum, the next stage becomes learning how to combine checkpoint inhibitors and agonists with each other as well as with traditional chemotherapeutic agents.

Abstract
BACKGROUND Cancer is known to modulate tumor-specific immune responses by establishing a microenvironment that leads to the upregulation of T-cell inhibitory receptors, resulting in the progressive loss of function and eventual death of tumor-specific T-cells. However, the ability of cancer to impact the functionality of the immune system on a systemic level is much less well characterized. Because cancer is known to predispose patients to infectious complications including sepsis, we hypothesized that the presence of cancer alters pathogen-directed immune responses on a systemic level. MATERIALS AND METHODS We assessed systemic T-cell coinhibitory receptor expression, cytokine production, and apoptosis in mice with established subcutaneous lung cancer tumors and in unmanipulated mice without cancer. RESULTS Results indicated that the frequencies of programmed death-1-positive, B and T lymphocyte attenuator-positive, and 2B4(+) cells in both the CD4(+) and CD8(+) T-cell compartments were increased in mice with localized cancer relative to non-cancer controls, and the frequencies of both CD4(+) and CD8(+) T-cells expressing multiple different inhibitory receptors were increased in cancer animals relative to non-cancer controls. Additionally, 2B4(+)CD8(+) T-cells in cancer mice exhibited reduced interleukin-2 and interferon-γ, whereas B and T lymphocyte attenuator-positive CD8(+) T-cells in cancer mice exhibited reduced interleukin-2 and tumor necrosis factor. Conversely, CD4(+) T-cells in cancer animals demonstrated an increase in the frequency of annexin V(+) apoptotic cells. CONCLUSIONS Taken together, these data suggest that the presence of cancer induces systemic T-cell exhaustion and generalized immune suppression.

Phenotypic T cell exhaustion in a murine model of bacterial infection in the setting of pre-existing malignancy. PLoS One 2014; 9:e93523.

Abstract
While much of cancer immunology research has focused on anti-tumor immunity both systemically and within the tumor microenvironment, little is known about the impact of pre-existing malignancy on pathogen-specific immune responses. Here, we sought to characterize the antigen-specific CD8+ T cell response following a bacterial infection in the setting of pre-existing pancreatic adenocarcinoma. Mice with established subcutaneous pancreatic adenocarcinomas were infected with Listeria monocytogenes, and antigen-specific CD8+ T cell responses were compared to those in control mice without cancer. While the kinetics and magnitude of antigen-specific CD8+ T cell expansion and accumulation was comparable between the cancer and non-cancer groups, bacterial antigen-specific CD8+ T cells and total CD4+ and CD8+ T cells in cancer mice exhibited increased expression of the coinhibitory receptors BTLA, PD-1, and 2B4. Furthermore, increased inhibitory receptor expression was associated with reduced IFN-γ and increased IL-2 production by bacterial antigen-specific CD8+ T cells in the cancer group. Taken together, these data suggest that cancer's immune suppressive effects are not limited to the tumor microenvironment, but that pre-existing malignancy induces phenotypic exhaustion in T cells by increasing expression of coinhibitory receptors and may impair pathogen-specific CD8+ T cell functionality and differentiation.

Abstract
Globally, Lung cancer is the leading cause of cancer-related death of high morbidity and mortality with poor prognosis, which needs some more effective and less toxic therapies. The immunotherapies offer a novel approach for the treatment of patients with non-small cell lung cancer (NSCLC) in both the adjuvant and palliative disease settings. A number of promising immunotherapies based on different mechanism have now been evaluated showing an increasing response rate. Moreover, further phase II/III clinical trials will be indicated to explore its value. These include checkpoint inhibitors (anti-CTLA4 antibody, anti-PD-1 antibody, anti-PD-L1 antibody), active vaccination (L-BLP25 liposome vaccine, Belagenpumatucel-L vaccine, MAGE-A3 protein vaccine) and adoptive vaccination (CIK cells). The purpose of this paper will draw a summary on the theory, clinical trials, toxicity and problems to be solved of the immunotherapies in NSCLC.
