To provide an overview of the latest research on tumor-associated macrophages (TAMs) and their role in gynecological malignancies, focusing on polarization-related signaling pathways and the use of nano-drug delivery systems (NDDSs) for targeted TAM therapy.
Approach:
Overview of TAMs: Discusses the role of TAMs in the tumor microenvironment (TME) and their classification into M1 and M2 phenotypes.
Signaling Pathways: Explores the complex regulatory network that influences TAM polarization, including transcription factors, gene editing, metabolic reprogramming, and epigenetic modifications.
NDDSs in Therapy: Examines the potential of NDDSs for clinical translation of immunotherapies targeting TAMs.
Challenges and Future Directions: Discusses the challenges in clinical translation and future research directions for immunotherapy in gynecological cancers.
Key Findings:
TAMs account for up to 50% of the cellular composition in some solid tumors.
M2-type macrophages, which promote tumor progression, typically predominate in the TME.
Recent advancements in single-cell RNA sequencing have revealed the complexity of macrophage subsets beyond the M1/M2 dichotomy.
Nanoparticle-based nanomedicine delivery systems have potential for clinical application in macrophage-targeted immunotherapy.
Interpretation:
Understanding the signaling pathways involved in TAM polarization is crucial for developing novel therapeutic strategies in gynecological malignancies.
Limitations:
Research on drugs targeting TAMs is still in early stages.
Challenges remain in the clinical translation of TAM-targeted therapies.
Conclusion:
In-depth investigation into TAM polarization mechanisms is essential for advancing drug development and clinical applications in gynecological cancers.
