Research Area

Our work has traditionally focussed on T-cell ligands and the receptors that recognise them. More recently, we have become interested in precisely what T-cells target during successful immunotherapy for solid cancer or during natural spontaneous remission. This has necessitated that we build pipelines for the discovery of what T-cell receptors (TCRs) of unknown specificity recognise. These pipelines have enabled us to determine that many of the T-cells from these remarkable patients have capacity to recognise most forms of cancer via new mechanisms. We aim to use these TCRs and the ligands they recognise to build the next generation of cancer therapies.

Team Description

Our diverse, passionate and dedicated group believe that we can learn from those rare individuals that clear end-stage solid cancers and build the next generation of successful immunotherapies for cancer
