Figure 1.
Proliferation of autologous T cells on stimulation with CLL cells in the presence of IL-2 and IL-7. Shown are T-cell numbers (× 100 000) after 0, 14, and 28 days of in vitro culture using CD40L-transduced (CD40L-AAV), GFP-transduced (GFP-AAV), or CD40-stimulated native CLL cells (CD40-/nat.CLL) as APCs without antigenic peptide pulsing.
