Abstract

Abstract Tumor antigens derived from somatic mutations, or indels, are referred to as mutation-derived tumor antigens (MTAs) but are also known as neoantigens,or tumor-specific antigens. Evidence suggests that MTAs play a significant role in the endogenous adaptive immune response to tumors, and in the induced response following treatment with checkpoint inhibitors such as anti-CTLA-4 or anti-PD-1. This session will cover the concept of shared neoantigens in cancer and vaccine approaches to elicit adaptive antitumor immunity. Citation Format: Nina Bhardwaj.
