Researchers develop new precision medicine technology for cancer immunotherapy

CAR T-cell therapy and antibody treatments are two types of targeted immunotherapies that have revolutionized the fields of cancer care. However, there are still significant challenges in identifying cancer cell surface proteins as targets for immunotherapies. A research group at Lund University in Sweden is well on their way as they have developed a new precision medicine technology that allows for comprehensive mapping of the entire tumor cell surface antigen landscape in patients. The method developed by the research team, “Tumor Surfaceome Mapping, TS-MAP,” allows direct analysis of all accessible tumor cell surface antigens in patient tumor tissue. In a close collaboration between neurosurgery, oncology and advanced proteomics in Lund, the researchers were able to identify several tumor cell surface antigens in fresh tissue from patients with aggressive brain tumors for which there is currently no effective treatment. An important advantage of the TS-MAP technology is that it provides a complete picture of the cell surface antigens displayed on the surface of the cancer cell, as well as information about specific cell surface antigens that have a high capacity to infiltrate cancer cells, and can destroy them from within.
