Abstract:
Long noncoding RNAs (lncRNAs), which lack protein-coding ability, can regulate cancer cell growth, proliferation, invasion, and metastasis. Tumor-associated macrophages (TAMs) are key components of the tumor microenvironment that have a significant impact on cancer progression. Small extracellular vesicles (sEV) are crucial mediators of intercellular communications. Cancer cell and macrophage-derived sEV can carry lncRNAs that influence the onset and progression of cancer. Dysregulation of lncRNAs, TAMs, and sEV is widely observed in tumors which makes them valuable targets for cancer immunotherapy. In this review, we summarize current updates on the interactions among sEV, lncRNAs, and TAMs in tumors and provide new perspectives on cancer diagnosis and treatment.
Insights
Long noncoding RNAs (lncRNAs) within extracellular vesicles (sEV) interact with tumor-associated macrophages (TAMs) to influence cancer progression. Understanding these interactions offers new avenues for cancer immunotherapy and diagnosis.

Main Methods:
- Literature review of studies investigating lncRNAs, TAMs, and sEV in cancer.
- Analysis of the mechanisms by which cancer cell and macrophage-derived sEV transport lncRNAs.
- Synthesis of findings on the functional impact of these interactions on tumor progression.
Main Results:
- lncRNAs carried by sEV can modulate TAM functions and influence the tumor microenvironment.
- The dysregulation of lncRNAs, TAMs, and sEV is a common feature in various tumors.
- These interactions are critical for cancer cell invasion, metastasis, and overall progression.
Conclusions:
