Sex-based differences in the lung immune microenvironment are associated with an increased risk of lung cancer in women. J Thorac Cardiovasc Surg 2024:S0022-5223(24)00617-2. [PMID: 39019152 DOI: 10.1016/j.jtcvs.2024.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 05/31/2024] [Accepted: 07/06/2024] [Indexed: 07/19/2024]
Abstract
OBJECTIVE Lung cancer remains a major cause of mortality worldwide, necessitating further understanding of carcinogenesis and its driving factors, including those influenced by sex-dependent variables. We hypothesized that sex-specific lung immune composition may contribute to a greater risk of lung cancer in women. METHODS Data from 1056 lung cancer screenings were examined for an association between sex and lung cancer risk using time-to-event analyses. Immune profiling by flow cytometry was performed on male and female lungs of 3 independent mouse models: nontumor bearing, KRAS mutated, and urethane-exposed carcinogenic. A comparable analysis was performed on human bronchoalveolar lavage samples (n = 81) from patients with lung cancer. RESULTS Of the high-risk screening cohort examined, 60 patients (5.7%) developed lung cancer during median follow-up of 43.4 months. Multivariable stepwise modeling retained female sex (hazard ratio, 1.56; P < .01) and age (P < .01) as prognostic indicators for lung cancer development. Female lung immune profiles in patients included T-cell phenotypes consistent with exhaustion (eg, higher proportions of PD-1+ Ki67-; P = .02), an expanded pool of regulatory T-cells (P = .03), reduced effector T-cell frequencies (P = .008), and enhancements in suppressive myeloid populations (P = .02) versus male patients, and this is recapitulated in mouse studies. CONCLUSIONS Female smokers display higher risk for lung cancer. In murine models and humans, female sex is associated with robust immunosuppression within the lung. Further examination of this link will be important in developing immune-based approaches to lung cancer interception and their optimal application across the sexes.

Immune landscape of vulvar cancer patients treated with surgery and adjuvant radiotherapy revealed restricted T cell functionality and increased IL-17 expression associated with cancer relapse. Int J Cancer 2024; 154:343-358. [PMID: 37786948 DOI: 10.1002/ijc.34745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 08/31/2023] [Accepted: 09/01/2023] [Indexed: 10/04/2023]
Abstract
For vulvar cancers, radiotherapy is targeting cancer cells, but also affects the host immune system. As this may affect treatment outcome, in this prospective study, we characterized the individual T cell immune milieu induced by surgery and adjuvant radio +/- chemotherapy (aRT) systemically in the blood of vulvar cancer patients and found increased frequencies of Interleukin (IL)-17-producing CD4+ and CD8+ T cells after aRT while frequencies of Th1 and perforin-producing CD8+ killer cells were strongly diminished. Phenotypic characterization revealed enhanced expression of the ectonucleotidase CD39 on Th17 and Tc17 cells as well as CD8+ perforin+ cells after aRT. Furthermore, the aRT cohort exhibited increased proportions of Programmed Cell Death Protein (PD-1) expressing cells among Th1 and CD8+ perforin+ cells, but not among Th17 and Tc17 cells. High post-therapeutic levels of Th17 and Tc17 cells and low proportions of Th1 and CD8+ perforin+ cells expressing PD-1 was associated with reduced recurrence free survival on follow-up. In conclusion, our study defines individual therapy-induced changes in the cellular immune milieu of patients and their association with cancer relapse. Our results may help to explain differences in the individual courses of disease of vulvar cancer patients and suggest PD-1 and IL-17 as targets for immunotherapy in vulvar cancer.

Abstract
The onset and progression of oral cancer are accompanied by a dynamic interaction with the host immune system, and the immune cells within the tumor microenvironment play a pivotal role in the development of the tumor. By exploring the cellular immunity of oral cancer, we can gain insight into the contribution of both tumor cells and immune cells to tumorigenesis. This understanding is crucial for developing effective immunotherapeutic strategies to combat oral cancer. Studies of cancer immunology present unique challenges in terms of modeling due to the extraordinary complexity of the immune system. With its multitude of cellular components, each with distinct subtypes and various activation states, the immune system interacts with cancer cells and other components of the tumor, ultimately shaping the course of the disease. Conventional two-dimensional (2D) culture methods fall short of capturing these intricate cellular interactions. Mouse models enable us to learn about tumor biology in complicated and dynamic physiological systems but have limitations as the murine immune system differs significantly from that of humans. In light of these challenges, three-dimensional (3D) culture systems offer an alternative approach to studying cancer immunology and filling the existing gaps in available models. These 3D culture models provide a means to investigate complex cellular interactions that are difficult to replicate in 2D cultures. The direct study of the interaction between immune cells and cancer cells of human origin offers a more relevant and representative platform compared to mouse models, enabling advancements in our understanding of cancer immunology. This review explores commonly used 3D culture models and highlights their significant contributions to expanding our knowledge of cancer immunology. By harnessing the power of 3D culture systems, we can unlock new insights that pave the way for improved strategies in the battle against oral cancer.

Associations between RORγt and T-bet Expressions, clinicopathological indices and survival rate in oral Squamous cell carcinoma patients. Cytokine 2023; 163:156116. [PMID: 36621309 DOI: 10.1016/j.cyto.2022.156116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 12/22/2022] [Accepted: 12/22/2022] [Indexed: 01/08/2023]
Abstract
BACKGROUND Oral cancers are the sixth most common cancers around the world. According to the pivotal role of immune cells in the pathogenesis of oral squamous cell carcinoma (OSCC), as the frequent form of malignant epithelial neoplasm in the oral cavity, we investigated the association between the expression of RORγt and T-bet genes as two transcription factors, clinicopathologic indices, and survival rate. METHODS AND MATERIALS Forty-two OSCC paraffin embded-blocks tissue samples and their surgical healthy margins (as a control group) were collected. Demographic information like age and gender, and medical history including tumor stage/grade, and following-up time were registered. The RORγt and T-bet expression were assessed by qPCR. The overall survival (OS) and disease free survival (DFS) were analyzed by SPSS V.23 software. RESULTS The expression of RORγt and T-bet genes in OSCC patients were significantly higher than in surgical healthy margins (P < 0.001). Both expression demonstrated a significant difference between surgical healthy margins and tumor tissues related to gender and clinicopathological indices including stage and grade (P < 0.05). The expression of both genes in stage I patients was significant compared to stage IV (P < 0.05). The relation between expressions, OS, and DFS with clinical stage and histological grade of tumors was not statistically significant (P > 0.05). CONCLUSION Overexpression of RORγt and T-bet in OSCC patients with higher grade and stage in compare to surgical healthy margin highlighted their critical role in OSCC pathogenesis including oral epithelial cell differentiation, tumorigenesis process, and malignant transformation. Moreover, both mentioned genes can apply as prognostic biomarkers in OSCC patients. We suggest surgical healthy margin be considered as valuable biological area.

Abstract
BACKGROUND The immune responses play significant roles in the onset, progression, and outcome of oral squamous cell carcinoma (OSCC). CD4+ regulatory T cells (Tregs) significantly impact tumor immunity. However, their role in OSCC development remains elusive. METHODS In a carcinogen-induced mouse OSCC model, interleukin-23 receptor (IL-23R) expression on Tregs and Treg function were determined by flow cytometry. IL-23R overexpression in Tregs was achieved by lentiviral infection, followed by evaluation of the expression of Forkhead box P3 (Foxp3), T-bet, retineic-acid-receptor-related orphan nuclear receptor gamma t, and cytokines by flow cytometry. Adoptive transfer assays were applied to analyze the function of IL-23R- overexpressing Tregs in vivo. The cellular sources of IL-23 were also determined by flow cytometry. RESULTS IL-23R- Tregs and IL-23R+ Tregs were found in the tongues but not spleens of OSCC-bearing mice. IL-23R+ Tregs expressed lower Foxp3 but higher T-bet than IL-23R- Tregs. IL-23R- Tregs produced abundant IL-10 and transforming growth factor (TGF)-β, while IL-23R+ Tregs produced lower IL-10 and TGF-β but remarkably higher interferon (IFN)-γ. Furthermore, IL-23R+ Tregs possessed more phosphorylated signal transducer and activator of transcription (STAT3) and STAT4 than IL-23R- Tregs. IL-23R+ Tregs were less immunosuppressive than IL-23R- Tregs, as evidenced by weaker inhibition of activated conventional T cells. IL-23R overexpression in splenic Tregs remarkably reduced the expression of IL-10 and TGF-β but increased IFN-γ expression when Tregs were adoptively transferred into OSCC-bearing mice. In the OSCC microenvironment, macrophages, dendritic cells, and malignant OSCC cells produced IL-23 which might modulate the function of IL-23R+ Tregs. CONCLUSIONS This study unveils Treg heterogeneity, thus deepening the understanding of Treg biology and tumor immunity in OSCC.

Abstract
The goal of investigation was the development of oral therapeutic vaccine against cancer on basis of antigenic regulatory protein HPV16 E2 encoded by the “early” hpv16 E2 gene.The aim. To study tumour growths in mice lungs inoculated with cancer HeLa cells and then vaccinated with vaccine material of transgenic tomato with the gene/protein HPV16 E2, and to study the activation of the immunogenesis of T-lymphocytes in mice after oral vaccination with HPV16 E2.Materials and methods. Proliferating cancer HeLa cells, mice peripheric blood mononuclear cells, splenocytes, intact and isolated lungs of mice were used in the study. Elispot was used for the evaluation of increasing of immunogenicity.Results. “Early” proteins HPV16 E6 or HPV16 E7 did not reveal any effect on HeLa cells. The regulatory antigenic “early” protein HPV16 E2 drastically degraded HeLa cells recorded by trypane blue. Four types of tumours were found in mice lung lobes placed in the suspension of cancer HeLa cells for 2–5 days: 1 – peripheral round tumours on epithelium, 2 – central tumours in the area of tracheal carina, 3 – pneumonialike peripheral cancer on lung lobes which was very similar to small-round-cell lung sarcoma with hyperchromic nuclei and 4 – Pancoast-like cancer in apical parts of lung lobe. Patterns of normal developed lung tissues were viewed on slices of lungs infected with HeLa in the presence of E2 simultaneously. The very high contents of γ‑interferon, CD4/CD8 T lymphocytes, T cell receptor and apoptotic enzymes: granzyme B, perforin and granulysine – were detected in blood and splenocytes of mice vaccinated with HPV16 E2.Conclusion. The study is promising for the development of an oral therapeutic vaccine based on a plant expression system (tomatoes) with the HPV16 E2 antigenic protein against lung cancer, cervical cancer and other types of cancer.

Abstract
Objective To investigate the function and regulatory mechanisms of methylenetetrahydrofolate dehydrogenase (MTHFD) family genes in oral squamous cell carcinoma (OSCC), especially focus on their regulating role in tumor immunity. Methods The publicly available data from the TCGA database were used to investigate the expression pattern and regulatory role of MTHFD family genes in OSCC. More importantly, the involvement of MTHFD family genes in tumor immunity was investigated in terms of immune and stromal cell infiltration in tumor microenvironment, tumor-infiltrating immune cells, and immunomodulatory genes (e.g., immunoinhibitory genes and immunostimulatory genes). Statistical analysis was performed using R software packages and public web servers. Results MTHFD family genes were considerably upregulated in OSCC as compared with normal oral tissue. Patients with high MTHFD2 expression presented worse survival outcomes than those with low MTHFD2 expression. Functional enrichment analysis showed that the top 100 positively and negatively correlated genes of the MTHFD family genes were significantly enriched in several KEGG pathways, including cell cycle, spliceosome, DNA replication, and Th17 cell differentiation. As a result of tumor immunity analysis, MTHFD2L expression was found to be negatively related to the Estimate-Stromal-Immune score in OSCC; however, there was no statistical significance between the Estimate-Stromal-Immune score and MTHFD1, MTHFD1L, or MTHFD2 in OSCC. Additionally, MTHFD family genes were found to be significantly positively correlated with tumor-infiltrating immune cells, including Treg and Th17 cells. Moreover, MTHFD family genes were significantly correlated with several immune inhibitory genes such as CD274 and CTLA4 and several immune-stimulatory genes such as CXCL12, CXCR4, and TMIGD2. Conclusion Given the expression pattern, prognostic value, biological functions, and involvement in tumor immunity, MTHFD family genes could serve as potential therapeutic biomarkers in targeting tumor immunity in oral cancer.

Abstract
The present article compares, side-by-side, cancer and autoimmune diseases in terms of innate and adaptive immune cells involvement, MHC Class I and Class II expression, TGFβ effect, immune modulating drugs effect and the effect of reactive oxygen species. The change in the inflammatory immune reaction during the progress of cancer and the effect of this change on the comorbidity of autoimmune diseases and cancer are discussed. The similar inflammatory properties of autoimmune diseases and early cancer, and the contrasting inflammatory properties of autoimmune diseases and advanced cancer elucidate the increased incidence of many types of cancer in patients with pre-existing autoimmune diseases and the decreased cancer-specific mortality of these patients. Stage-dependent effects of reactive oxygen-species on tumor proliferation are an additional probable cause for these epidemiological observations. The relationship: {standardized incidence ratio (SIR)} > {cancer-specific hazard ratio (HR)} for cancer patients with a history of autoimmune diseases is substantiated and rationalized.

Abstract
Circular RNAs (circRNAs), which form as covalently closed loop structures, have several biological functions such as regulation of cellular behavior by adsorbing microRNAs. However, there is limited information of circRNAs in oral squamous cell carcinoma (OSCC). Here, we aimed to elucidate the roles of aberrantly expressed circRNAs in OSCC. CircRNA microarray showed that circRNA-102450 was down-regulated in OSCC cells. Clinical validation of circRNA-102450 was performed using highly sensitive droplet digital PCR in preoperative liquid biopsy samples from 30 OSCC patients. Interestingly, none of 16 studied patients with high circRNA-102450 had regional lymph node metastasis (RLNM), whereas 4 of 14 studied patients (28.5%) with low expression had pathologically proven RLNM. Overexpressed circRNA-102450 significantly inhibited the tumor metastatic properties of cell proliferation, migration, and invasion. Furthermore, circRNA-102450 directly bound to, and consequently down-regulated, miR-1178 in OSCC cells. Taken together, circRNA-102450 has a tumor suppressive effect via the circRNA-102450/miR-1178 axis and may be a novel potential marker of RLNM in OSCC patients.

Abstract
OBJECTIVE The objective of this review is to decipher the biological implications of the immune factors in the tumour microenvironment in oral cancer. The restoration of balance between tumour tolerance and tumour eradication by the host immune cells is critical to provide effective therapeutic strategies. DESIGN The specific role of the stromal and the immune components in oral cancer was reviewed with a tailored search strategy using relevant keywords. The articles were retrieved from bibliometric databases indexed in PubMed, Scopus, and Embase. An in silico analysis was performed to identify potential drug candidates for immunotherapy, by accessing the Drug-Gene Interactions Database (DGIdb) using the rDGIdb package. RESULTS There is compelling evidence for the role of the cellular and extracellular components of the tumour microenvironment in inducing immunosuppression and progression of oral cancer. The druggable candidates specifically targeting the immune system are a viable option in the treatment of oral cancer as they can regulate the tumour microenvironment. CONCLUSION A complex interaction between the tumour and the immunological microenvironment influences the disease outcome in oral cancer. Targeting specific components of the immune system might be relevant, as immunotherapy may become the new standard of care for oral cancer.

Abstract
Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades. Cancer has a close relationship with the immune system and, although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity, studies have emphasized their roles in cancer pathogenesis. The Th17 immune response profile is involved in several types of cancer including urogenital, respiratory, gastrointestinal, and skin cancers. This type of immune response exerts pro and antitumor functions through several mechanisms, depending on the context of each tumor, including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment. Among other factors, the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential, which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells. Interleukin (IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment, which allow Th17 cells to prevail in tumors. Moreover, the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers, being associated with variable clinical outcomes. The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.

Recent advances in the role of Th17/Treg cells in tumor immunity and tumor therapy. Immunol Res 2021; 69:398-414. [PMID: 34302619 DOI: 10.1007/s12026-021-09211-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Accepted: 06/30/2021] [Indexed: 12/12/2022]
Abstract
Th17 and Treg cells play an important role in regulating tissue inflammation and maintaining the stability of the immune system. They regulate inflammatory responses, participate in the occurrence and development of autoimmune diseases and tumors, and determine the disease progress. Malignant tumor is one of the diseases with the highest mortality rate in the world. However, the efficacy of traditional treatment is limited, so it is necessary to find safe and efficient treatment methods. Studies have shown that the balance of Th17/Treg cells plays a critical role in tumor progression. In this paper, we review the antitumor and tumor-suppressing effects of Th17/Treg cells, and new strategies for tumor therapy, combined with new research hotspots such as immune checkpoint therapy, miRNA-related gene therapy, and metabolic pathway regulation of Th17/Treg cell differentiation and tumor generation. The synergistic therapy is expected to be widely used in the future clinical practice, providing a new choice for the prevention and treatment of malignant tumors.

[PMID: 33749974 DOI: 10.1111/odi.13853] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 03/01/2021] [Accepted: 03/16/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The aim of our study was to determine the impact of Th17/Treg imbalance on the progression and malignant transformation of oral submucosal fibrosis (OSF). MATERIALS AND METHODS To assess Th17 and Treg expression, overall 52 peripheral blood samples from OSF, oral squamous cell carcinoma (OSCC) patients, and healthy donors were analyzed by flow cytometry. Thirty normal oral mucosa, 72 OSF, and 90 OSCC samples were analyzed by immunohistochemistry. RESULTS In peripheral blood samples, in OSCC with OSF, Th17 and Treg expression were significantly higher than those in OSF and OSCC without OSF as confirmed by immunohistochemistry. During OSF progression, Th17 and Th17/Treg ratio showed an increasing trend, while Treg expression showed a decreasing trend. Treg expression was significantly higher in OSCC with OSF than in OSF and OSCC without OSF, whereas the Th17/Treg ratio was significantly lower in OSCC with OSF. Treg expression was significantly correlated with smoking and clinical stage. Th17/Treg ratio was significantly associated with tumor size, lymph node metastasis, and clinical stage. A low Th17/Treg ratio was significantly associated with poor prognosis. CONCLUSIONS Th17/Treg ratio is a potential diagnostic indicator for OSF occurrence and malignant transformation and was an independent prognostic factor for OSCC.
