Patent Summary

A method for identifying neoantigens that can be presented by tumor cells for cancer immunotherapy. The method employs a novel approach to neoantigen identification that integrates mass spectrometry data with computational models to predict peptide presentation by tumor MHC alleles. The method trains models on peptide sequences from tumor samples and presents them to MHC alleles, generating likelihoods of peptide presentation. These likelihoods are then used to select the most promising neoantigens for vaccine development. The approach addresses the limitations of current methods by incorporating mass spectrometry data and computational models to improve peptide presentation predictions.
