Figure 4From: In vitro enhancement of dendritic cell-mediated anti-glioma immune response by graphene oxideAntigen-specific immune lysis of the target cells. PBMCs were pretreated with un-pulsed DCs or GO-Ag-pulsed DCs. The treated PBMCs were co-incubated with either the Ag-loaded T2 cells (A) or the control peptide-loaded T2 cells (B) (mean ± std, n = 6). The stars indicate statistically significant differences between the groups.Back to article page
