N2 - γδ T lymphocytes play an important role in immune reactions towards infections and malignancies. In particular, Vγ9-Vδ1+ T lymphocytes are thought to play protective antiviral roles in human CMV infection. Recently, Vδ1+ T lymphocytes were proposed to also have anti- B-CLL reactivity. Here we report a case of 48-year-old man who received allogeneic stem cell transplantation for progressive B-CLL. Within one year after transplantation, lymphoma relapsed despite a dramatic increase of Vδ1+ T cells in the patient's blood. In vitro killing assays revealed activity of patient's γδ cells against CMV target cells, but not against the relapsing lymphoma-cells. This argues for a contribution of Vδ1+ cells in the immune reaction against CMV reactivation, but does not support a strong correlation of expanded Vδ1+ T cells and favorable disease outcome in B-CLL patients.
