Professor Yvonne Jones talks about cell-cell communication and how this can help us develop new drugs. Cells communicate through receptors on their surface; however, when these finely tuned systems don't work correctly, diseases can be triggered. Professor Yvonne Jones has been working to identify the structural biology of cell surface recognition and signalling complexes. Receptors embedded in the surface are potential targets for therapeutic intervention in many diseases including cancer. Professor Jones is director of the Cancer Research UK Receptor Structure Research Group.
