Tumor neoantigens: from basic research to clinical applications.

Area of Science:

• Oncology
• Immunology
• Cancer Research

Background:

• Tumor neoantigens are foreign proteins specific to cancer cells, absent in normal tissues.
• Neoantigens are recognized by T cell receptors (TCRs) in association with major histocompatibility complex (MHC) molecules.
• They are critical drivers of tumor-specific T cell-mediated immune responses and successful cancer immunotherapies.

Purpose of the Study:

• To systematically review recent advances in understanding and identifying tumor-specific neoantigens.
• To explore the role of neoantigens in current cancer immunotherapies.
• To discuss neoantigen-based therapeutic strategies and their future clinical applications.

Main Methods:

• Literature review of recent studies on tumor neoantigens.
• Analysis of neoantigen identification methods and their clinical relevance.
• Synthesis of information on neoantigen-based therapeutic approaches.

Main Results:

• Neoantigens are ideal immunotherapy targets due to their non-self nature.
• Neoantigen-based personalized vaccines and adoptive T cell transfers show promising preliminary results.
• Neoantigens play significant roles in immune escape, immunoediting, and response to immune checkpoint inhibitors.

Conclusions:

• Understanding and identifying tumor neoantigens are advancing cancer immunotherapy.
• Neoantigen-based strategies hold significant potential for future clinical applications in personalized cancer treatment.
