We previously established a system for functional discovery and validation of T cell receptor ligands which is:
1) modular and compatible with complementary approaches to TCR discovery
2) adaptable to several levels of throughput, including screening millions of potential interactions and enabling de novo ligand identification, andÂ
3) highly sensitive, including a reporter cell line and system for T cell activation and a method for increasing antigen presentation to T cells
These elements together present a platform with the highest likelihood of discovering physiologically relevant interactions between T cells and their targets, as well as the ability to discover the most interactions per donor. Our early work established the sensitivity of the system in a number of proof-of-concept studies. We are currently building on this work to develop a new generation of lymphocyte activation reporter systems which will leverage infrastructure at University of Birmingham to perform high-throughput de-orphanisation studies across a wide range of ligand types, lymphocyte subsets, and human diseases.
