Regulatory T Cells in Tumor Microenvironment: Therapeutic Approaches and Clinical Implications.
Regulatory T cells (Tregs), previously referred to as suppressor T cells, represent a distinct subset of CD4+ T cells that are uniquely specialized for immune suppression. They are characterized by the constitutive expression of the transcription factor FoxP3 in their nuclei, along with CD25 (the IL-2 receptor α-chain) and CTLA-4 on their cell surface. Tregs not only restrict natural killer cell-mediated cytotoxicity but also inhibit the proliferation of CD4+ and CD8+ T-cells and suppress interferon-γ secretion by immune cells, ultimately impairing an effective antitumor immune response. Treg cells are widely recognized as a significant barrier to the effectiveness of tumor immunotherapy in clinical settings. Extensive research has consistently shown that Treg cells play a pivotal role in facilitating tumor initiation and progression. Conversely, the depletion of Treg cells has been linked to a marked delay in tumor growth and development.
期刊介绍：
Each month, the journal publishes easy-to-assimilate, up-to-the minute reports of experimental findings by researchers using a wide range of the latest techniques. Promoting the aims of cell biologists worldwide, papers reporting on structure and function - especially where they relate to the physiology of the whole cell - are strongly encouraged. Molecular biology is welcome, as long as articles report findings that are seen in the wider context of cell biology. In covering all areas of the cell, the journal is both appealing and accessible to a broad audience. Authors whose papers do not appeal to cell biologists in general because their topic is too specialized (e.g. infectious microbes, protozoology) are recommended to send them to more relevant journals. Papers reporting whole animal studies or work more suited to a medical journal, e.g. histopathological studies or clinical immunology, are unlikely to be accepted, unless they are fully focused on some important cellular aspect.
These last remarks extend particularly to papers on cancer. Unless firmly based on some deeper cellular or molecular biological principle, papers that are highly specialized in this field, with limited appeal to cell biologists at large, should be directed towards journals devoted to cancer, there being very many from which to choose.
