Joining the immunotherapy revolution: Adoptive cell therapy against cancer
During cancer development, tumour cells generate neo-antigens on their surface, which can be recognized as foreign by cytotoxic CD8+ T lymphocytes (CTL). Following recognition of the tumour-associated antigens, tumour cells are targeted for elimination. A current cancer therapy in the clinic involves manufacture of tumour-specific CTL capable of destroying specifically tumour cells, and injection of the CTL into patients. While this revolutionary therapy shows great promise, impairment of the CTL in many patients prevents its full potential to be realised. To overcome these limitations, we are characterising the mechanisms that cause anti-cancer CTL inactivation.
