Crosstalk between cancer-associated fibroblasts and immune cells in the tumor microenvironment: new findings and future perspectives

Molecular Cancer, Journal Year: 2021, Volume and Issue: 20(1)

Published: Oct. 11, 2021

Abstract Cancer-associated fibroblasts (CAFs), a stromal cell population with cell-of-origin, phenotypic and functional heterogeneity, are the most essential components of tumor microenvironment (TME). Through multiple pathways, activated CAFs can promote growth, angiogenesis, invasion metastasis, along extracellular matrix (ECM) remodeling even chemoresistance. Numerous previous studies have confirmed critical role interaction between cells in tumorigenesis development. However, recently, mutual effects immune (TIME) been identified as another key factor promoting progression. The TIME mainly consists distinct populations islets is highly associated antitumor immunological state TME. interact tumor-infiltrating well other within via secretion various cytokines, growth factors, chemokines, exosomes effector molecules, consequently shaping an immunosuppressive TME that enables cancer to evade surveillance system. In-depth interactions, particularly complicated mechanisms connecting cells, might provide novel strategies for subsequent targeted immunotherapies. Herein, we shed light on recent advances regarding direct indirect crosstalk infiltrating further summarize possible immunoinhibitory induced by In addition, present current related CAF-targeting immunotherapies briefly describe some future perspectives CAF research end.

Machine learning-based integration develops an immune-derived lncRNA signature for improving outcomes in colorectal cancer

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Feb. 10, 2022

Long noncoding RNAs (lncRNAs) are recently implicated in modifying immunology colorectal cancer (CRC). Nevertheless, the clinical significance of immune-related lncRNAs remains largely unexplored. In this study, we develope a machine learning-based integrative procedure for constructing consensus lncRNA signature (IRLS). IRLS is an independent risk factor overall survival and displays stable powerful performance, but only demonstrates limited predictive value relapse-free survival. Additionally, possesses distinctly superior accuracy than traditional variables, molecular features, 109 published signatures. Besides, high-risk group sensitive to fluorouracil-based adjuvant chemotherapy, while low-risk benefits more from bevacizumab. Notably, abundant lymphocyte infiltration, high expression CD8A PD-L1, response pembrolizumab. Taken together, could serve as robust promising tool improve outcomes individual CRC patients.

Modulation of the tumor microenvironment and mechanism of immunotherapy-based drug resistance in breast cancer

Molecular Cancer, Journal Year: 2024, Volume and Issue: 23(1)

Published: May 7, 2024

Abstract Breast cancer, the most frequent female malignancy, is often curable when detected at an early stage. The treatment of metastatic breast cancer more challenging and may be unresponsive to conventional therapy. Immunotherapy crucial for treating but its resistance a major limitation. tumor microenvironment (TME) vital in modulating immunotherapy response. Various microenvironmental components, such as cancer-associated fibroblasts (CAFs), tumor-associated macrophages (TAMs), myeloid-derived suppressor cells (MDSCs), are involved TME modulation cause resistance. This review highlights role stromal microenvironment, including involvement CAF-TAM interaction, alteration metabolism leading failure, other latest strategies, high throughput genomic screening, single-cell spatial omics techniques identifying immune genes regulating emphasizes therapeutic approach overcome through CAF reprogramming, TAM polarization, metabolism, alterations.
