Abstract:
In this article, we present a comprehensive, updated, and elucidative review of the current knowledge on the function played by tumor-derived vesicles (TDVs) in the crosstalk between tumor and immune cells. Characterization of the structure, biogenesis, and the major functions of TDVs is reported. The review focuses on particular ways of suppression or activation of CD4+/CD8+ T cells by tumor-derived vesicles. Tumor-derived vesicles play an important role in the suppression of antitumor immunity. During the last 15 years, vesicle research has elucidated and improved our knowledge about the role of the vesicles in intercellular communication. Nevertheless, there are still blinds spots concerning vesicle heterogeneity and isolation methods, their uptake by target cells, and the role of mRNA in T-cell transformation or suppression. Along with the substantial progress in understanding of the role of tumor-derived vesicles in intercellular communication, novel antitumor therapy strategies based on vesicle inhibition in a tumor microenvironment are likely to appear very soon.
Insights
Tumor-derived vesicles (TDVs) mediate communication between cancer and immune cells, often suppressing anti-tumor immunity. Further research into TDV heterogeneity and function could lead to new cancer therapies.
Area of Science:
- Immunology

Background:
- Tumor-derived vesicles (TDVs) are crucial mediators of intercellular communication in the tumor microenvironment.
- TDVs play a significant role in modulating immune responses, particularly T cell activity.
- Recent advancements have deepened our understanding of vesicle-mediated communication over the past 15 years.
Purpose of the Study:
- To provide a comprehensive review of the current knowledge on TDVs' function in tumor-immune cell crosstalk.
- To elucidate the structure, biogenesis, and major functions of TDVs.
- To focus on the mechanisms by which TDVs suppress or activate CD4+ and CD8+ T cells.
Main Methods:
- Literature review and synthesis of existing research on TDVs.
- Analysis of studies characterizing TDV structure, biogenesis, and function.
- Focus on research detailing TDV interactions with T cells (CD4+ and CD8+).
Main Results:
