CXC Chemokine-Driven Vascular Reprogramming: Modulating Tumor Vasculature to Boost Therapeutic Response

Area of Science:

• Oncology
• Immunology
• Vascular Biology

Background:

• Aberrant tumor vasculature contributes to cancer progression, immune evasion, and treatment resistance.
• Current vascular normalization strategies, mainly VEGF-focused, lack molecular insights into vessel function.
• There is a critical need for advanced methods to assess therapeutic windows and improve vascular-immune interactions.

Purpose of the Study:

• To introduce a chemokine-centered framework for understanding and manipulating tumor vascular functionality.
• To propose novel molecular tools for real-time vascular assessment and therapeutic stratification.
• To outline targeted CXC chemokine strategies for enhanced cancer therapy.

Main Methods:

• Developed a chemokine-centered perspective focusing on the CXC chemokine network.
• Analyzed mechanistic dimensions: bidirectionality, temporal dynamics, and tissue specificity.
• Proposed the functional vascular normalization score (FVNS) and the chemokine-guided vascular normalization window (VNW).

Main Results:

• The CXC chemokine network dynamically regulates vascular functionality through interconnected mechanisms.
• FVNS and VNW offer molecular tools for real-time vascular assessment and treatment planning.
• CXC-targeted strategies like CXCR2/CXCR4 blockade and CXCL9/10/11 augmentation show therapeutic potential.

Conclusions:

• A chemokine-focused paradigm offers a functional and implementable approach to integrate vascular normalization and immune modulation in cancer treatment.
• This framework enables personalized therapeutic strategies by extending and refining the VNW.
• The proposed tools and strategies can enhance the efficacy of cancer therapies by targeting tumor vasculature and immune responses.
