Allogeneic, HLA-matched MLR.
HLA.A2+ CLL cells were infected with either AAV/CD40L or AAV/EGFP and incubated for 72 hours with naive CLL cells (1:10) derived from the same patient. Then 1 × 104 CLL cells irradiated with 200 Gy were cocultured with 1 × 105 purified healthy donor T cells (HLA.A2+) for another 96 hours, pulsed with [3H]-thymidine and T-cell proliferation determined 6 hours later (cpm). The data from one representative patient are depicted. Error bars represent SEM of triplicate measurements.
