Invention Summary:
Scientists from the Rutgers University and Stanford University have discovered T cell receptor molecules targeting a novel antigen upregulated in cancer. This discovery has potential value for cancer-targeting therapies, particularly CAR T therapies. Currently, a limited number of CAR T therapies indicated for a narrow range of cancer types are in the clinic, so expanding the repertoire of antigens and cancers that CAR T cells can successfully target is critical for broader utilization of this powerful technology.
Researchers profiled the specificities of tumor-infiltrating T cells from lung cancer patients and discovered T cells targeting a novel antigen associated with Epstein-Barr Virus (EBV) and upregulated in lung cancer. Specifically, these T cell receptors recognize a peptide derived from the EBV protein LMP2 as well a similar peptide derived from human TMEM161A that is overexpressed on cancer cells. The T cell receptor sequences could be used as the basis for cancer treatments including cell therapies or molecular therapies that target this cancer antigen. In addition, cells or molecules recognizing this EBV-related antigen could also help treat chronic active EBV and EBV-associated autoimmune diseases like lupus.
