Fig. 3From: In vivo imaging of the immune response upon systemic RNA cancer vaccination by FDG-PETDose dependency of the immune response after 2Â cycle of vaccination as measured by spleen FDG uptake and FACS analysis. Spleen FDG uptake determined by ex vivo biodistribution 24Â h (a) and 48Â h (b). A clear dose response is more evident after 24Â h, indicating the major role of rapid activating processes. c Dose response for T cell proliferation at days 1 and 2. d Dose response of CD25 expression on gp70-specific CD8+ cells (day 2)Back to article page
