We obtained the morphologically, cytofluorometrically, and functionally mature dendritic cells from rats that were pulsed with antigens of the C6 glioma tissue extract. The concentrations of angiogenesis antigens (VEGF, VEGFR-1, and VEGFR-2) and periglioma zone proteins (GFAP, connexin 43, and BSAT1) in the pulsing extract were measured by ELISA. Our results drove us to a conclusion that despite mature phenotype of pulsed dendritic cell, the antigenic composition of glioma tissue extracts should be modified.
