Cancer immunotherapy has opened up a new frontier in cancer treatment, but the lack of specificity and resistance to targeted therapies have hindered their effectiveness. Recent research has focused on the role of cancer-associated fibroblasts (CAFs) in immune regulation and their impact on tumor progression. CAFs interact with immune cells to create a tumor immune microenvironment (TIME) that promotes malignant tumor progression, thereby contributing to the failure of cancer immunotherapies. This review highlights the immunosuppressive function of CAFs, the mechanisms of CAFs-immune cell interactions, and discusses potential CAF-targeted therapeutic strategies for future investigation.
Cancer immunotherapy has opened a new landscape in cancer treatment, however, the poor specificity and resistance of most targeted therapeutics have limited their therapeutic efficacy. In recent years, the role of CAFs in immune regulation has been increasingly noted as more evidence has been uncovered regarding the link between cancer-associated fibroblasts (CAFs) and the evolutionary process of tumor progression. CAFs interact with immune cells to shape the tumor immune microenvironment (TIME) that favors malignant tumor progression, a crosstalk process that leads to the failure of cancer immunotherapies. In this review, we outline recent advances in the immunosuppressive function of CAFs, highlight the mechanisms of CAFs-immune cell interactions, and discuss current CAF-targeted therapeutic strategies for future study.
