Techniques

In vitro

  • Generation of peptide-specific CD8 T cell lines (CTLL)
  • Isolation of lymphocytes from different organs (spleen, lymph node, lungs, thymus, bone marrow, liver)
  • Immunomagnetical cell separation
  • IFN-y based ELISPOT assay
  • 51Cr-release assay
  • HPLC fractionation
  • Cytofluorometric analyses (incl. multimer staining, CFSE analysis)
  • Isolation and quantification of endogenously processed peptides from cell and organ extracts
  • Quantification of infectious virus in organs

In vivo (mouse model)

  • Preemptive cytoimmunotherapy of acute mCMV infection with ex vivo isolated CD8 T cells as well as with in vitro cultivated CTLL (adoptive T cell transfer)
  • Experimental bone marrow transplantation (syngeneic, allogeneic)
  • In vivo killing of peptide loaded target cells
