Description

Identifying major histocompatibility complex (MHC)-bound peptides recognized by specific T-cell receptors (TCRs) is key to developing personalized T-cell therapies. We developed an unbiased pipeline combining immunopeptidomics with TCR functional assays in pancreatic ductal adenocarcinoma (PDAC). MHC class I peptides were fractionated by liquid chromatography (LC) and identified via mass spectrometry (MS). Correlating TCR activity with peptide abundance across fractions enabled robust identification of candidate TCR ligands
