For recurrent or metastasized prostate cancer only limited therapeutic options are available besides hormonal therapy or chemotherapy with docetaxel. Therefore, also other treatment modalities like immunotherapeutic strategies are being evaluated. Immunization against prostate specific antigen (PSA), the most common target molecule, can be enhanced with the use of immunostimulating CpG-oligonucleotides (ODN). CpG-ODN, recognized by toll-like receptor 9 on plasmatocytoid dendritic cells, resulted in up-regulation of costimulatory molecules as well as proinflammatory cytokines, characteristic for Th1 immune responses in murine in vitro flt3-BMDC cultures. Finally, immunization of C57/BL-6 mice with PSA-peptide in combination with CpG-ODN demonstrated robust induction of PSA-petide specific CTL. Thus, CpG-DNA as immune stimulants might be of potential in immunotherapeutic strategies against prostate cancer.
