Cellular Components of the Tumor Environment in Gliomas-What Do We Know Today?

Area of Science:

• Oncology
• Cancer Biology
• Neuro-oncology

Background:

• Historically, cancer research focused on tumor cell molecular properties.
• The tumor microenvironment (TME), comprising non-neoplastic cells, is now recognized as critical for tumor growth, maintenance, and resistance.

Purpose of the Study:

• To review current knowledge on cellular components within the glioma TME.
• To focus on molecular properties, expression patterns, and influence on glioma biology.

Main Methods:

• Literature review of recent advancements in glioma TME research.
• Synthesis of information on cellular interactions and their impact on tumor behavior.

Main Results:

• Expanded understanding of TME components, including macrophage phagocytosis of glioma cells.
• Identified the role of thyroid-stimulating hormone in glioma growth.
• Highlighted lymphocyte migration, chemoresistance similarities to stem cells, and novel immunotherapies.

Conclusions:

• The glioma TME is a complex ecosystem influencing tumor progression.
• Further research into TME cellular components and their interactions is vital for developing effective brain tumor treatments.
• Emerging immunotherapies targeting TME cells show promise for clinical application.
