A molecular image revealing the interaction between skin cancer cells and T-cells – the cells which protect our body against disease - has been produced by the School of Medicine.
We have used X-ray crystallography to determine the structure of the best ever studied human cancer antigen in complex with a human T-cell receptor. This 'antigen' molecule is upregulated on the surface of human melanoma cells and enables killer T-cells to identify and eliminate these cancerous cells using their T-cell receptor. We anticipate wide interest in this structure as it is only the second human cancer/T-cell receptor complex ever solved. Our T-cells are really designed to eliminate 'foreign molecules' and they are crucial for the elimination of pathogens. T-cells perform less well at eliminating cancer as cancer cells are derived from our own tissue and pose the immune system a greater challenge.

We have recently published a groundbreaking study in Nature Medicine that utilises engineered T-cells which can target and kill all natural escape variants of HIV in vitro. This discovery has attracted worldwide interests and has been covered by a number of mainstream publications and news broadcasters!! Links can be found below:
