Abstract
Treatment with T cells genetically engineered to express tumor-reactive T cell receptors (TCRs), known as TCR-gene therapy (TCR-T), is a promising immunotherapeutic approach for patients with cancer. The identification of optimal TCRs to use and tumor antigens to target are key considerations for TCR-T. In this issue of the JCI, Bear and colleagues report on their use of in vitro assays to characterize four HLA-A*03:01- or HLA-A*11:01-restricted TCRs targeting the oncogenic KRAS G12V mutation. The TCRs were derived from healthy donors or patients with pancreatic cancer who had received a vaccine against mutant KRAS. The most promising TCRs warrant testing in patients with KRAS G12V-positive cancers.
