The impact of immunopeptidomics: From basic research to clinical implementation

Area of Science:

• Immunology
• Proteomics
• Mass Spectrometry

Background:

• The immunopeptidome, peptides presented by MHC/HLA molecules, reflects cellular health and is altered by perturbations like infection or cancer.
• Immunopeptidomics provides a detailed snapshot of this peptide repertoire.

Purpose of the Study:

• To review recent immunopeptidomics studies across basic, pre-clinical, and clinical research domains.
• To highlight the role of immunopeptidomics in understanding disease and developing novel therapies.

Main Methods:

• Extraction and analysis of peptides presented by MHC/HLA molecules.
• High-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS) for deep immunopeptidome profiling.

Main Results:

• Studies have elucidated antigen processing, HLA restriction, and disease mechanisms.
• Exploration of the antigenic landscape has enabled pre-clinical immune targeting strategies.

Conclusions:

• Immunopeptidomics is crucial for understanding cellular states and disease.
• This field is paving the way for innovative cancer treatments and clinical applications.
