An international research team, headed by Professor Sine Reker Hadrup from DTU Nanotech, has developed a new screening tool to improve cancer immunotherapy.

A promising, but still experimental, cancer treatment called T-Cell Receptor (TCR) gene therapy takes advantage of T-cell’s ability to recognize and kill cancerous cells. Here the doctors retrieve white blood cells from the patient and program them to attack cancer cells by adding specific T-cell receptors. Afterwards they are put back into the patient to fight the cancer. A major challenge is that the T-cell receptors can accidentally misidentify healthy cells as cancer cells.

This new screening tool maps the T-cell receptors to get a better understanding of how and what they recognize as malicious cells. Reading - what the researchers have termed - the fingerprint of T-cell receptors makes it possible to discard the most risky and potentially harmful T-cell receptors before they are used for treatment. The intention is that this technique together with additional methods will make TCR gene therapy safer for the patients.
