Antigenic competition in the generation of multi-virus-specific cell lines for immunotherapy of human cytomegalovirus, polyomavirus BK, Epstein-Barr virus and adenovirus infection in haematopoietic stem cell transplant recipients
Original language description
Adoptive transfer of multivirus-specific T cell lines (MVST) is an advanced tool for immunotherapy of virus infections after hematopoietic stem cell transplantation (HSCT). Their preparation includes activation of donor virus-specific T cells by the mixture of oligopeptides derived from immunodominant antigens of several most harmful viruses, i.e. human cytomegalovirus (HCMV), polyomavirus BK (BKV), Epstein-Barr virus (EBV) and adenovirus (ADV). The aim of our study was to find out whether antigenic competition may have an impact on the expansion of virus-specific T cells. MVST from several heathy blood donors were generated using a pulse of overlapping oligopeptides (PepMixes™, derived from the IE1 and pp65 CMV antigens, VP1 and LTAG BKV antigens, BZLF1 and EBNA1 proteins of EBV and hexon protein from ADV) and short time culture in the presence of IL-7 and IL-4. The amount of virus-specific T cells in MVST was measured by ELISPOT and flow cytometry after re-stimulation with individual antigens. To evaluate antigenic competition, MVST were expanded either with a complete set of antigens or with the mixture lacking some of them.
