Schematic representation of cancer immunogenomics workflow for neoantigen discovery.
Normal reference tissue (ie, PBMC) and tumor tissue is obtained and undergoes DNA
whole exome and RNA sequencing to identify somatic, nonsynonymous mutations.
Tumor-specific mutations are then filtered using computational software to prioritize
neoantigens based on expression, predicted patient-specific HLA binding affinity, and
likelihood of endogenous proteosomal processing. Peptides corresponding to candidate
high-quality neoantigens are then manufactured and administered back to the patient as
a personalized vaccine. PBMC, peripheral blood mononuclear cell.
