Abstract

Introduction: Tight junctions (TJs) and their constituent proteins play pivotal roles in cellular physiology and anatomy by establishing functional boundaries within and between neighboring cells. While the involvement of TJ proteins, such as claudins, in cancer is extensively studied, studies highlighting their interaction with immune system are still meager. Studies indicate that alterations in cytokines and immune cell populations can affect TJ proteins, compromising TJ barrier function and exacerbating pro-inflammatory conditions, potentially leading to epithelial cell malignancy. Disrupted TJs in established tumors may foster a pro-tumor immune microenvironment, facilitating tumor progression, invasion, epithelial-to-mesenchymal transition and metastasis. Although previous literature contains many studies describing the involvement of TJs in pathogenesis of malignancies their role in modulating the immune microenvironment of tumors is just beginning to be unleashed.

Areas covered: This article for the first time attempts to discern the importance of interaction between TJs and immune microenvironment in malignancies. To achieve the above aim a thorough search of databases like PubMed and Google Scholar was conducted to identify the recent and relevant articles on the topic.

Expert opinion: Breaking the vicious cycle of dysbiosis/infections/chemical/carcinogen-induced inflammation-TJ remodeling-malignancy-TJ dysregulation-more inflammation can be used as a strategy to complement the effect of immunotherapies in various malignancies.

紧密连接蛋白在塑造恶性肿瘤免疫环境中的作用。
导言:紧密连接(TJ)及其组成蛋白通过在相邻细胞内和细胞间建立功能边界,在细胞生理学和解剖学中发挥着关键作用。虽然 TJ 蛋白(如 claudins)与癌症的关系已被广泛研究,但有关它们与免疫系统相互作用的研究仍然很少。研究表明,细胞因子和免疫细胞群的改变会影响 TJ 蛋白,损害 TJ 屏障功能并加剧促炎状况,从而可能导致上皮细胞恶性肿瘤。已确诊肿瘤中被破坏的 TJ 可能会形成有利于肿瘤的免疫微环境,促进肿瘤进展、侵袭、上皮细胞向间质转化和转移。尽管以往的文献中有许多研究描述了 TJs 参与恶性肿瘤发病机制的情况,但它们在调节肿瘤免疫微环境方面的作用才刚刚开始显现:本文首次尝试揭示 TJ 与免疫微环境之间的相互作用在恶性肿瘤中的重要性。为了达到上述目的,我们对PubMed和谷歌学术等数据库进行了全面搜索,以确定近期与该主题相关的文章:打破菌群失调/感染/化学/致癌物质诱导的炎症-TJ重塑-恶性肿瘤-TJ失调-更多炎症的恶性循环,可作为补充各种恶性肿瘤免疫疗法效果的一种策略。

期刊介绍: Expert Review of Clinical Immunology (ISSN 1744-666X) provides expert analysis and commentary regarding the performance of new therapeutic and diagnostic modalities in clinical immunology. Members of the International Editorial Advisory Panel of Expert Review of Clinical Immunology are the forefront of their area of expertise. This panel works with our dedicated editorial team to identify the most important and topical review themes and the corresponding expert(s) most appropriate to provide commentary and analysis. All articles are subject to rigorous peer-review, and the finished reviews provide an essential contribution to decision-making in clinical immunology. Articles focus on the following key areas: • Therapeutic overviews of specific immunologic disorders highlighting optimal therapy and prospects for new medicines • Performance and benefits of newly approved therapeutic agents • New diagnostic approaches • Screening and patient stratification • Pharmacoeconomic studies • New therapeutic indications for existing therapies • Adverse effects, occurrence and reduction • Prospects for medicines in late-stage trials approaching regulatory approval • Novel treatment strategies • Epidemiological studies • Commentary and comparison of treatment guidelines Topics include infection and immunity, inflammation, host defense mechanisms, congenital and acquired immunodeficiencies, anaphylaxis and allergy, systemic immune diseases, organ-specific inflammatory diseases, transplantation immunology, endocrinology and diabetes, cancer immunology, neuroimmunology and hematological diseases.
