Broad-spectrum defenders: γδ T cells take on a multitude of immune challenges

Abstract

Abstract A recent article in Proceedings of the National Academy of Sciences investigated γδ T cell antigen specificity in mice and humans, in which the authors show that γδ T cell antigen specificity is not constrained to one epitope. Rather, γδ T cells recognize a broad range of diverse antigens containing similar chemical structures or properties. In this News and Views, the importance of γδ T cell antigen polyspecificity during immune responses is highlighted.
