T cell large granular lymphocytic leukemia (T-LGLL) is a lymphoproliferative disorder involving clonally expanded T cell clones and is not fully understood. Here the authors show that the rest of the immune repertoire is interconnected with the T-LGLL clonotype(s) and is more mature, cytotoxic and clonally restricted than in other cancers and autoimmune disorders.
