Fig. 1From: Strategies of adoptive T -cell transfer to treat refractory viral infections post allogeneic stem cell transplantationAdoptive T cell transfer. Adoptive transfer of multivirus-specific T cells from a healthy donor to a patient in order to treat refractory viral infections post stem cell transplantation (HSCT). Virus-specific T cells can be isolated by in vitro stimulation and expansion or direct selection of specific T cells ex vivo from peripheral blood of a seropositive donorBack to article page
