Immunometabolism has recently emerged on the forefront of cancer research as a new avenue to potentially develop more effective and targeted treatment options. Several pathologically altered metabolic targets across various cancer types have been identified, including lactate in aerobic glycolysis; tryptophan in amino acid metabolism; and arginine in the urea cycle. Numerous advancements have improved our understanding of the dual function of these targets in influencing immune functions as an auxiliary function to their well-established metabolic role. This paper provides a comprehensive overview of immunometabolism research and attempts to provide insight into potential immunometabolic targets in glioblastoma for the purpose of future development and study of targeted therapies.
