Metabolic Interplay in the Tumor Microenvironment: Implications for Immune Function and Anticancer Response.

Area of Science:

• Oncology
• Cancer Metabolism
• Immunology

Background:

• Malignant tumors exhibit high metabolic rates and depend on aerobic glycolysis (Warburg effect).
• Radiolabeled glucose analogs are used in PET scans for tumor staging and assessing treatment response.
• Conventional therapies like chemotherapy and radiotherapy cause significant toxicity by targeting rapidly dividing cells.

Purpose of the Study:

• To review metabolic differences between cancer and immune cells.
• To explore the role of the tumor microenvironment (TME) in cancer progression and immune evasion.
• To examine the potential of TME-targeted therapies for cancer treatment.

Main Methods:

• Review of existing literature on cancer metabolism, immunology, and the TME.
• Analysis of metabolic disparities between cancer cells and immune cells.
• Examination of the components and functions of the TME.

Main Results:

• Cancer cells' reliance on aerobic glycolysis impacts immune surveillance.
• The TME influences tumor progression, immune evasion, and therapeutic responses.
• TME-targeted therapies show promise in modulating the tumor environment to enhance anti-cancer immunity.

Conclusions:

• Understanding cancer cell metabolism and TME interactions is crucial for developing effective therapies.
• Targeting the TME offers a promising strategy to overcome treatment resistance and improve cancer control.
• Reprogramming the TME can potentially lead to better cancer outcomes, including cure.
