gammadelta T lymphocytes count is normal and expandable in peripheral blood of patients with follicular lymphoma, whereas it is decreased in tumor lymph nodes compared with inflammatory lymph nodes.

gammadelta T lymphocytes are attractive effector cells for immunotherapy. In vitro, they can be expanded and kill efficiently a variety of tumor cells. The frequency and distribution of gammadelta T lymphocytes were compared in tumor lymph nodes of 51 patients with follicular lymphoma lymph nodes (FL-LNs) and 28 patients with inflammatory lymph nodes (I-LNs). gammadelta and CD8 T lymphocytes were less abundant in FL-LNs than in I-LNs (p
