Sensitize Tumor Immunotherapy: Immunogenic Cell Death Inducing Nanosystems

Area of Science:

• Oncology
• Immunology
• Materials Science

Background:

• Low tumor immunogenicity hinders effective cancer immunotherapy.
• Therapeutic strategies like chemotherapy, radiotherapy, and phototherapy can induce immunogenic cell death (ICD).
• ICD releases tumor antigens and matures dendritic cells (DCs), boosting anti-tumor immune responses.

Purpose of the Study:

• To review the mechanisms and induction methods of ICD.
• To explore the relationship between ICD and tumor immunity.
• To examine advancements in using nanomaterials to induce ICD for enhanced cancer immunotherapy.

Main Methods:

• Review of existing literature on ICD inducers and cancer immunotherapy.
• Analysis of mechanisms by which ICD enhances anti-tumor immunity.
• Investigation of the role of nanosystems in modulating ICD and immune responses.

Main Results:

• Single ICD inducers often fail to achieve complete tumor ablation or long-term immunity.
• Nanosystems offer a promising approach to enhance ICD induction and tumor immunotherapy.
• Nanomaterial properties influence ICD levels and potential toxic side effects.

Conclusions:

• Nanomaterial-based ICD inducers hold significant potential for improving cancer immunotherapy.
• Further research is needed to optimize nanomaterial design for enhanced ICD and reduced toxicity.
• This review provides theoretical guidance for developing clinical applications of nanomaterial-based ICD inducers.
