Pyroptosis-Inducing Biomaterials Pave the Way for Transformative Antitumor Immunotherapy

Area of Science:

• Biomedical Engineering
• Immunology
• Materials Science

Background:

• Pyroptosis is a potent cell death pathway that can overcome tumor immunosuppression and enhance anti-tumor immunity.
• Initiating pyroptosis for therapeutic benefit is challenging due to complex biological mechanisms and potential interference from other cell death pathways.
• Gasdermin (GSDM) proteins are key effectors of pyroptosis, making them attractive therapeutic targets.

Purpose of the Study:

• To provide a comprehensive overview of pyroptosis-inducing biomaterials for cancer therapy.
• To explore the design principles, functions, and anti-tumor efficacy of these materials.
• To highlight challenges and future directions for clinical applications.

Main Methods:

• Review of existing literature on pyroptosis mechanisms and gasdermin protein targeting.
• Analysis of rationally designed gasdermin protein-targeting biomaterials.
• Evaluation of the anti-tumor immune response stimulated by these biomaterials.

Main Results:

• Gasdermin protein-targeting biomaterials can effectively induce pyroptosis.
• These biomaterials demonstrate capacity for safe and effective stimulation of anti-tumor immune function.
• Different design strategies exist for activating various gasdermin proteins.

Conclusions:

• Rationally designed biomaterials offer a viable strategy for inducing pyroptosis and enhancing anti-tumor immunity.
• Targeting specific gasdermin proteins provides diverse design options for pyroptosis-inducing biomaterials.
• Further development of these biomaterials holds significant potential for clinical cancer therapy.
