cGAS-STING pathway regulated by spatiotemporal heterogeneity of tumor microenvironment and precision therapy strategies in lung cancer

Area of Science:

• Immunology
• Oncology
• Molecular Biology

Background:

• The cGAS-STING pathway is crucial for innate immunity.
• It plays a complex, dual role in lung cancer, influencing both anti-tumor immunity and immune escape.
• Tumor microenvironment (TME) heterogeneity significantly impacts cGAS-STING pathway activity.

Purpose of the Study:

• To systematically review the pro- and anti-tumorigenic roles of the cGAS-STING pathway in lung cancer.
• To explore how TME spatiotemporal heterogeneity modulates cGAS-STING pathway activity.
• To discuss cGAS-STING-driven precision immunotherapy and AI optimization strategies.

Main Methods:

• Systematic review of existing literature.
• Analysis of the interplay between TME components (cell types, physicochemical gradients) and cGAS-STING signaling.
• Integration of immunometabolism and TME heterogeneity concepts.

Main Results:

• The cGAS-STING pathway's function is context-dependent within the heterogeneous TME.
• Spatiotemporal variations in the TME dynamically alter cGAS-STING pathway activity.
• Immunometabolism and TME heterogeneity are critical factors influencing cGAS-STING pathway outcomes.

Conclusions:

• Understanding the dynamic interplay between TME heterogeneity and the cGAS-STING pathway is essential for developing effective lung cancer therapies.
• Targeting the cGAS-STING pathway, considering TME context, offers potential for novel immunotherapies.
• Integrating these factors may improve treatment strategies, overcome resistance, and enhance patient survival.
