Loss of alloreactivity after enrichment and expansion of CMV-specific T cells. (A) CD4+ T cells from either the PBMC fraction (d0) or the generated CMV-specific T-cell lines (later than d10) from 3 donors (LSA7, ▦; LSA8, ▪; LSA5, □) were stimulated with irradiated, mature third-party DCs. Proliferative responses are expressed as the median [3H]-thymidine incorporation (cpm) of the stimulated cells - [3H]-thymidine incorporation of the control. (B) CD8+ T cells purified from the PBMC fraction or the generated CMV-specific T-cell lines were plated with irradiated, mature third-party DCs. Numbers of CD8+ T cells were calculated by cell counting.
