Researchers at the National Institutes of Health have identified a collection of TCRs that specifically target mutated KRAS antigen. These TCRs exclusively recognize the G12D or G12V variants of mutated KRAS, which are common hotspot driver mutations expressed by a variety of epithelial cancers, including pancreatic, colorectal and lung cancer. The mutated KRAS variants are recognized by the TCRs in the context of HLA-A*11:01 or HLA-C*08:02. These TCRs can be used for a variety of experimental therapeutic, diagnostic and research applications.
