Adoptive cellular therapy for early cytomegalovirus infection after allogeneic stem-cell transplantation with virus-specific T-cell lines

Adoptive transfer of CMV-specific T cells offers the potential for reconstitution of viral immunity after allogeneic transplantation. However, the logistics of producing virus-specific T-cell clones has limited the application of cellular therapies. We treated 16 patients for CMV infection with polyclonal CMV-specific T-cell lines generated by short-term culture. Massive in-vivo expansions of CMV-specific cytotoxic T lymphocytes were observed,...
