The progress and prospects of targeting the adenosine pathway in cancer immunotherapy

Area of Science:

• Oncology
• Immunology
• Metabolism

Background:

• Cancer immunotherapy success is limited in many patients.
• Tumor immune evasion mechanisms require further investigation.
• Adenosine, accumulating in hypoxic tumors, influences the tumor microenvironment.

Purpose of the Study:

• To review the role of the adenosinergic axis in tumor immune evasion.
• To propose strategies for targeting adenosine to enhance anti-tumor immunity.
• To evaluate clinical data on adenosinergic pathway inhibitors.

Main Methods:

• Literature review of preclinical and clinical studies.
• Analysis of adenosine-receptor interactions within the tumor microenvironment.
• Evaluation of therapeutic strategies targeting the adenosinergic axis.

Main Results:

• The adenosinergic pathway is a significant mechanism of tumor immune evasion.
• Inhibiting adenosine signaling can suppress tumor progression.
• Adenosine pathway inhibitors show potential for enhancing immunotherapy outcomes.

Conclusions:

• Targeting the adenosinergic axis is a promising strategy to overcome immunotherapy resistance.
• Further clinical evaluation of adenosine pathway inhibitors is warranted.
• Optimizing strategies to boost anti-tumor immunity by targeting adenosine is crucial.
