Role of B7 Costimulation in the Induction of T and B Cell Responses by Dendritic Cells in vivo
The adjuvant properties of dendritic cells have been amply demonstrated. A single injection of splenic DC, which have been pulsed extracorporeally with antigen, induces primary T (1) and B (2) cell responses in vivo. Recent reports have shown that tumor-bearing animals or patients can be immunized against their own tumors by injecting autologous DC pulsed with tumor associated antigens (3, 4). In vivo priming using elements of the immune system avoids the toxic effect of external adjuvants and leads to an antigen-specific, anamnestic immune response.
