Reactivity of CTL clones directed against PR-3, RHAMM and Survivin, as well as CTLAML clones towards DCs nucleofected with FLT3-WT plus and minus FLT3-siRNA or FLT3-ITD. All approaches were carried out with and without the addition of FL. (a, b) HLA-A2+ DCs from a healthy donor were nucleofected with FLT3-WT-mRNA or FLT3-ITD-mRNA and co-cultivated with the different CTL clones with and without the addition of FL. Furthermore, the FLT3-WT+ DCs were additionally transfected with FLT3-siRNA. The supernatants were tested in an IFN-γ ELISA. (a, b) show the results of the ELISA with the CTL clones directed against PR-3, RHAMM and Survivin, as well as with the CTLAML clone nos 3, 8 and 12.
