Stem cell transplantation is used widely in the management of a range of diseases of the hemopoietic system. Patients are immunosuppressed profoundly in the early posttransplant period, and reactivation of cytomegalovirus (CMV) remains a significant cause of morbidity and mortality. Adoptive transfer of donor-derived CMV-specific CD8+ T cell clones has been(More)
Reactivation of CMV is a common complication following allogeneic haematopoietic SCT and is associated with significant morbidity and mortality. The relative importance of the CD4+ and CD8+ components of the CMV-specific immune response in protection from reactivation is unclear. The CMV-specific CD4+ and CD8+ immune response was measured at serial time(More)
Immune function in the elderly is associated with a number of phenotypic and functional abnormalities, and this phenomenon of immune senescence is associated with increased susceptibility to infection. The immune response to pathogens frequently declines with age, but the CD8(+) T-cell response to cytomegalovirus (CMV) is unusual, as it demonstrates a(More)
B-cell chronic lymphocytic leukemia is associated with immune suppression and an altered T-cell repertoire with expansion of memory cells. Cytomegalovirus (CMV) is a common herpes virus that elicits a strong virus-specific T-cell immune response after infection. We studied the CMV-specific CD4(+) T-cell response in 45 patients and 35 control subjects and(More)
