Abstract:
Glioblastoma multiforme is one of the deadliest human cancers and is characterized by a high degree of microglia and macrophage infiltration. The role of these glioma infiltrating macrophages (GIMs) in disease progression has been the subject of recent investigation. While initially thought to reflect an immune response to the tumor, the balance of evidence clearly suggests GIMs can have potent tumor-tropic functions and assist in glioma cell growth and infiltration into normal brain. In this review, we focus on the evidence for GIMs aiding mediating glioblastoma motility and invasion. We survey the literature for molecular pathways that are involved in paracrine interaction between glioma cells and GIMs and assess which of these might serve as attractive targets for therapeutic intervention.
Insights
Glioma infiltrating macrophages (GIMs) promote glioblastoma growth and invasion. Targeting molecular pathways between GIMs and glioma cells offers potential therapeutic strategies for this deadly brain cancer.
Area of Science:
- Neuro-oncology
- Cancer immunology
- Tumor microenvironment
Background:
- Glioblastoma multiforme is a highly aggressive brain tumor.
- Characterized by significant infiltration of microglia and macrophages.
- The role of these glioma infiltrating macrophages (GIMs) is under active investigation.
Purpose of the Study:
- To review the evidence for GIMs promoting glioblastoma motility and invasion.
- To identify molecular pathways involved in glioma cell and GIM paracrine interactions.
- To assess potential therapeutic targets within these pathways.
Main Methods:
- Literature review and synthesis of existing research.
- Analysis of molecular mechanisms underlying GIM-glioma cell communication.
- Evaluation of therapeutic potential of identified pathways.
Main Results:
- Evidence suggests GIMs possess tumor-promoting functions.
- GIMs actively contribute to glioma cell growth and brain infiltration.
- Specific paracrine signaling pathways mediate GIM-glioma cell interactions.
Conclusions:
