Dendritic cells expand Epstein Barr virus specific CD8+ T cell responses more efficiently than EBV transformed B cells.
Hum. Immunol. 66, 938-949 (2005)
Adoptive transfer of Epstein Barr virus (EBV) specific cytotoxic T lymphocytes (CTLs) has been successfully applied in the treatment of EBV associated post-transplant lymphoproliferative disease (PTLD). In most studies EBV transformed B cells (LCLs) have been used for the induction of EBV specific T cell lines. Application of this approach to other EBV associated tumors is difficult, because LCLs focus T cell expansion toward immunodominant EBV antigens that are not expressed in EBV associated Hodgkin's lymphoma and nasopharyngeal carcinoma. Therefore, we compared dendritic cells (DCs) with LCLs for CD8+ T cell stimulation against dominant and subdominant EBV antigens. DCs expanded tenfold more EBNA3A and LMP2 specific CD8+ T cells than LCL and also stimulated EBV specific CTL from PTLD patients. Both, DCs and LCLs stimulations led to the expansion of high affinity T cells, capable to target EBV transformed B cells. While LCLs and DCs expressed MHC class I and II products at similar levels, DCs showed a higher expression of costimulatory and adhesion molecules. This resulted in more efficient T cell conjugate formation with DCs than with LCLs. We propose the use of DCs for stimulation of EBV specific T cells in active or passive immunotherapy of EBV associated malignancies.
