25HC regulates the polarization of CD163+ macrophages in the immune microenvironment of triple-negative breast cancer through the interferon pathway
To investigate the TNBC-specific tumor immune microenvironment and the role of 25-hydroxycholesterol (25HC) in macrophage polarization, highlighting its potential therapeutic implications.
Key Findings:
25-hydroxycholesterol (25HC) was identified as a novel key regulator of macrophage polarization in TNBC.
An aberrantly activated interferon regulatory factor 7–cholesterol-25-hydroxylase–25HC axis inhibits CD163+ macrophage polarization, suggesting a unique mechanism in TNBC.
Interpretation:
This study delineates the link between dysregulated 25HC metabolism and macrophage polarization in TNBC, providing critical insights into the immunometabolic mechanisms that may underlie TNBC aggressiveness and therapeutic strategies.
Limitations:
The precise role of 25HC in the TNBC immune microenvironment was previously poorly defined, indicating a gap in current understanding.
Further studies are needed to fully elucidate the mechanisms and implications of 25HC in TNBC, which could inform future therapeutic approaches.
Conclusion:
The findings reveal a potential therapeutic target for TNBC through modulation of macrophage polarization.
