e17521 Background: Recurrent or progressive cervical cancer have limited second-line treatment options. Response rates are often poor to second-line therapy (average response rate of 15%). Identification of factors which predict response to immunotherapy and targets to enhance the immune response are critically needed in cervical cancer. Chronic inflammation can initiate an immune response in non-secondary lymphoid organs (SLO) and form a Tertiary Lymphoid Structure (TLS).

Abstract Targeting the tumor microenvironment (TME) to be more immune permissive is a potential strategy for enhancing immunotherapies, such as chimeric antigen receptor T cell (CAR-T) therapy, providing a promising avenue for treating aggressive tumors such as glioblastoma multiforme (GBM). Tertiary lymphoid structures (TLS) are ectopic lymphoid aggregates that arise in response to chronic inflammation and mimic the structure and function of secondary lymphoid organs. The spontaneous presence of TLS in some solid tumors, including GBM, is associated with improved clinical outcome and responsi

A tertiary lymphoid structure (TLS) is a special component in the immune microenvironment that is mainly composed of tumor-infiltrating lymphocytes (TILs), including T cells, B cells, DC cells, and high endothelial venules (HEVs). For cancer patients, evaluation of the immune microenvironment has a predictive effect on tumor biological behavior, treatment methods, and prognosis. As a result, TLSs have begun to attract the attention of researchers as a new potential biomarker. However, the composition and mechanisms of TLSs are still unclear, and clinical detection methods are still being explo

BackgroundTertiary lymphoid structures (TLSs) are immune aggregates in peripheral tissues that may support adaptive immune responses. Their presence has been associated with clinical response to checkpoint blockade therapy (CBT), but it is unknown whether TLS have prognostic significance independent of CBT in melanoma. We hypothesized that TLS in melanoma metastases would be associated with increased intratumoral lymphocyte infiltration, but that the intra-TLS immunological milieu would be distinct from the intratumoral immunological milieu.

Introduction: Tertiary lymphoid structures (TLSs), also known as ectopic lymphoid structures, are organized lymphoid-like aggregates that can form within the tumor microenvironment. TLSs exhibit similar structural and functional characteristics to secondary lymphoid organs, such as lymph nodes, and are associated with improved cancer prognosis and enhanced immune responses, including immune checkpoint blockade (ICB) therapies.

The study aimed to investigate the prognostic significance of TLS in patients with locally advanced ESCC receiving neoadjuvant chemoradiotherapy (CRT). Patients and Methods: We included two cohorts of locally advanced ESCC patients from two referral centers of Taiwan. Cohort A consisted of 99 patients treated with paclitaxel/cisplatin-based CRT, 69 of them being neoadjuvant CRT and 30

Tertiary lymphoid structure (TLS) is an ectopic lymphocyte aggregate formed in peripheral non-lymphoid tissues, including inflamed or cancerous tissue. Tumor-associated TLS serves as a prominent center of antigen presentation and adaptive immune activation within the periphery, which has exhibited positive prognostic value in various cancers. In recent years, the concept of maturity regarding TLS has been proposed and mature TLS, characterized by well-developed germinal centers, exhibits a more potent tumor-suppressive capacity with stronger significance. Meanwhile, more and more evidence show

ABSTRACTFirst considered as a negative epiphenomenon in autoimmune and inflammatory diseases, with possible deleterious consequences through the production of pathological autoantibodies and antiself T cells, tertiary lymphoid structures (TLS) have gained major scientific and clinical interest in cancer due to their association with better clinical outcomes and improved responses to immunotherapy. Studies have investigated the structure and plasticity of TLS in the context of tumors and the role of the TLS B‐cell compartment in contributing to the favorable clinical outcome of cancer patients.

ABSTRACTImmunotherapy of autoimmune diseases has expanded substantially, yet autoimmunity remains incurable, and patients suffer from chronic destructive tissue inflammation that fails to resolve. Mechanisms underlying the endurance of autoimmune memory and the lack of exhaustion are beginning to be understood. Here, we review emerging data on how decentralization of cellular immunity contributes to persistent autoimmune responses and chronicity of autoimmune tissue inflammation. Two processes are recognized as ensuring lasting immune memory: the generation of tissue‐resident memory T cells (T

Recent advances in immunotherapy have enabled rapid evolution of novel interventional approaches designed to reinvigorate and expand patient immune responses against cancer. An emerging approach in cancer immunology involves the conditional induction of tertiary lymphoid structures (TLS), which are non-encapsulated ectopic lymphoid structures forming at sites of chronic, pathologic inflammation. Cutaneous melanoma (CM), a highly-immunogenic form of solid cancer, continues to rise in both incidence and mortality rate, with recent reports supporting a positive correlation between the presence of

Tertiary lymphoid structures (TLS) are lymph node-like aggregates that can form in association with chronic inflammation or cancer. Mature TLS are organized into B and T cell zones, and are not encapsulated but include all cell types necessary for eliciting an adaptive immune response. TLS have been observed in various cancer types and are generally associated with a positive prognosis as well as increased sensitivity to cancer immunotherapy. However, a comprehensive understanding of the roles of TLS in eliciting anti-tumor immunity as well as the mechanisms involved in their formation and fun

Abstract Tertiary lymphoid structures (TLS) are ectopic lymphoid structures in cancers that are largely associated with favourable prognosis. However, the prognostic value of TLSs in oral squamous cell carcinoma (OSCC) is largely unknown, and the association between tumour infiltrating lymphocytes (TILs) and TLSs has been rarely explored in OSCC. In this study, associated markers of TLS, including peripheral node address (PNAd) in high endothelial venules, CD20 in B cells and CD3 in T cells, were examined in 168 OSCC patients, and survival analysis was performed between TLS-positive and TLS-ne

To mount an effective anti-tumor immune response capable of controlling or eliminating disease, sufficient numbers of lymphocytes must be recruited to malignant tissue and allowed to sustain their effector functions. Indeed, higher infiltration of T and B cells in tumor tissue, often referred to as “hot tumors”, is prognostic for patient survival and predictive of response to immunotherapy in almost all cancer types. The organization of tertiary lymphoid structures (TLS) in solid tumors is a unique example of a hot tumor whereby T and B lymphocytes aggregate with antigen presenting cells and h

Tertiary lymphoid structures in cancer Tertiary lymphoid structures (TLSs) are lymphoid formations that are found in nonlymphoid tissues. TLS can develop in inflamed tissues and are associated with chronic inflammatory disorders, autoimmunity, and cancer. In the setting of tumors, TLSs facilitate the influx of immune cells into the tumor site and have therefore attracted interest as a means of improving anticancer immunity and favorable treatment response in patients.

The success of immunotherapy approaches, such as immune checkpoint blockade and cellular immunotherapy with genetically modified lymphocytes, has firmly embedded the immune system in the roadmap for combating cancer. Unfortunately, the majority of cancer patients do not yet benefit from these therapeutic approaches, even when the prognostic relevance of the immune response in their tumor entity has been demonstrated. Therefore, there is a justified need to explore new strategies for inducing anti-tumor immunity. The recent connection between the formation of ectopic lymphoid aggregates at tumo

Recent studies have shown that tertiary lymphoid structures (TLS), which resemble lymphoid structures, are closely linked to the immune response and tumor prognosis. The functions of the tertiary lymphoid structure-related genes (TLS-RGs) in the tumor microenvironment (TME) are poorly understood.

Abstract Radiotherapy (RT) plays a key role in the tumour microenvironment (TME), impacting the immune response via cellular and humoral immunity. RT can induce local immunity to modify the TME. It can stimulate dendritic cell maturation and T-cell infiltration. Moreover, B cells, macrophages and other immune cells may also be affected. Tertiary lymphoid structure (TLS) is a unique structure within the TME and a class of aggregates containing T cells, B cells and other immune cells.
