Main Methods:

• Comprehensive review of past clinical and basic science studies.
• Analysis of evidence regarding glioma cell of origin.
• Examination of genomic alterations driving gliomas.
• Study of tumor heterogeneity and neuronal-glioma interactions.

Main Results:

• Gliomas arise from specific cells of origin and contain brain tumor-initiating cells.
• Multiple genomic alterations drive glioma development.
• Complex tumor heterogeneity and neuronal-glioma networks are characteristic of gliomas.
• These factors contribute to treatment resistance and poor prognosis.

Conclusions:

• The biology of gliomas is complex, involving specific cellular origins and genomic drivers.
• Tumor heterogeneity and interactions with the neuronal microenvironment are critical.
• These insights are vital for identifying novel therapeutic targets for improved glioma treatment outcomes.
