Figure 2 Representative flow cytometry plots from a single glioma patient vaccinated<br />

with autologous tumor lysate pulsed DCs. PBMC isolated pre- (left column) and<br />

post-vaccination (right column) were stained with HLA restricted tetramers for HER-2,<br />

gp100, and MAGE-1 (y-axis). Additionally, cells were stained for the CD8 antigen<br />

(x-axis). Plots indicate a significant increase in the number of cells that registered as<br />

double positive (i.e. bound to antigen specific tetramers and positive for CD8). This<br />

demonstrates an expansion in the populations of CTL specific for these TAAs in this<br />

patient following DC vaccination.
