Tumor-specific T-cell help is associated with improved survival in melanoma

Abstract

Despite success with immune checkpoint inhibitors, clinical benefit from cancer vaccines remains elusive. Combined targeting of melanoma-specific CD4(+) and CD8(+) T-lymphocyte epitopes was associated with improved survival compared with targeting either alone, or when a nonspecific helper epitope was used. We discuss the potential role of antigen-specific CD4 help.
