CMV-CTL for the Treatment of CMV Infection After HSCT

Human cytomegalovirus (CMV) infection is a major cause of morbidity and mortality for recipients of allogeneic hematopoietic stem cell transplantation(HSCT). we propose to study the immunologic and virologic effects of donor derived CMV specific cytotoxic T lymphocyte (CMV-CTL) given to transplant recipients CMV antigen peptides will be used to induce the CMV antigen specific T lymphocytes derived from donor peripheral blood mononuclear cells for a period of 18\~21 days.The patients will receive CMV-CTL cells when they are sero-positive for CMV-DNA 30 days after transplant. The CMV-DNA level will be monitored weekly after transfusion.
