Glioblastoma: Relationship between Metabolism and Immunosuppressive Microenvironment

Area of Science:

• Neuro-oncology
• Immunology
• Cancer Metabolism

Background:

• Glioblastoma (GBM) is the most lethal adult brain cancer.
• GBM features a highly immunosuppressive tumor microenvironment (TME).
• The TME critically influences tumor growth and response to therapy.

Purpose of the Study:

• To review the roles of genetic alterations and metabolic pathways in shaping the GBM TME.
• To explore how these factors contribute to an immunosuppressive state.
• To overview current and emerging therapeutic strategies targeting these mechanisms.

Main Methods:

• Literature review focusing on genetic alterations in GBM.
• Analysis of metabolic pathways within the GBM TME.
• Synthesis of research on immune cell modulation by genetic and metabolic factors.

Main Results:

• Specific genetic alterations promote GBM immune evasion.
• Altered tumor metabolism fuels immunosuppression and tumor progression.
• Interplay between genetics and metabolism significantly impacts TME composition and function.

Conclusions:

• Targeting genetic drivers and metabolic vulnerabilities offers promising therapeutic avenues for GBM.
• Understanding the interplay between genetics and metabolism is crucial for overcoming GBM immunosuppression.
• Combined strategies may enhance treatment efficacy against aggressive brain tumors.
