Abstract:
Members of the nuclear receptor (NR) superfamily orchestrate cellular processes that can impact on numerous cancer hallmarks. NR activity plays important roles in the tumor microenvironment by controlling inflammation and immune responses. We summarize recent insights into the diverse mechanisms by which NR activity can control tumor inflammation, the roles of different NRs in modulating tumor immunity, and the biological features of immune cells that express specific NRs in the context of cancer. NR-dependent alterations in tumor inflammation and immunity may be amenable to pharmacological manipulation and offer new clues regarding the development of novel cancer therapeutic regimens.
Insights
Nuclear receptors (NRs) influence cancer by regulating inflammation and immunity within the tumor microenvironment. Understanding these NR roles offers potential for new cancer therapies.
Area of Science:
- Molecular Biology
- Immunology
- Oncology
Background:
- Nuclear receptors (NRs) are key regulators of cellular functions with significant implications for cancer development.
- NRs play a critical role in the tumor microenvironment, influencing inflammation and immune responses.
- Dysregulation of NR activity is linked to various cancer hallmarks.
Purpose of the Study:
- To summarize recent findings on how NR activity controls tumor inflammation.
- To elucidate the roles of different NRs in modulating tumor immunity.
- To explore the biological characteristics of NR-expressing immune cells in cancer.
Main Methods:
- Literature review and synthesis of recent research findings.
- Analysis of mechanisms by which NRs impact tumor inflammation.
- Examination of NR expression in immune cells within the tumor context.
Main Results:
- NRs employ diverse mechanisms to control tumor-associated inflammation.
- Specific NRs differentially modulate anti-tumor immunity and immune cell functions.
- NR activity significantly impacts the composition and behavior of immune infiltrates.
Conclusions:
- NR-dependent modulation of tumor inflammation and immunity presents therapeutic opportunities.
- Targeting NRs could lead to novel strategies for cancer treatment.
- Further research into NR functions in cancer immunity is warranted.
