In vivo, forces applied to molecular interactions between T cells and antigen-presenting cells are essential for specific foreign antigen recognition. A new technology, BATTLES, applies force to thousands of T cells interacting with tens of candidate antigens to identify antigens capable of efficient T cell activation. The method improves throughput over current methods that profile force-dependent interactions.
