CpG Oligodeoxynucleotides Alter Lymphocyte and Dendritic Cell Trafficking in Humans

Abstract

Our results show that (a) CpG-ODN with GM-CSF may not be an effective adjuvant strategy for hTERT peptide vaccines but (b) GM-CSF/CpG-ODN causes a PDC-mediated chemokine response that recruits T-cell migration to the peripheral tissues. These findings suggest a novel therapeutic role for targeted injections of CpG-ODN to direct lymphocyte migration to specific sites such as the tumor bed.
