Cancer neoantigens that arise from tumor mutations are drivers of tumor-specific T cell
responses, but identification of T cell-recognized neoantigens in individual patients is
challenging. Previous methods have restricted antigen discovery to selected HLA alleles,
thereby limiting the breadth of neoantigen repertoires that can be uncovered. Here, we
develop a genetic neoantigen screening system that allows sensitive identification of CD4+
and CD8+ T cell-recognized neoantigens across patients' complete HLA genotypes.
Abstract
Cancer neoantigens that arise from tumor mutations are drivers of tumor-specific T cell responses, but identification of T cell-recognized neoantigens in individual patients is challenging. Previous methods have restricted antigen discovery to selected HLA alleles, thereby limiting the breadth of neoantigen repertoires that can be uncovered. Here, we develop a genetic neoantigen screening system that allows sensitive identification of CD4+ and CD8+ T cell-recognized neoantigens across patients’ complete HLA genotypes.
