HHV-6-specific T-cell Reconstitution Among Children and Adolescents After Allogeneic Stem.

"day 10, peripheral blood mononuclear cells were re-stimulated with the virus antigen U54 for 6 hours and, thereafter, stained for surface markers (CD3, CD4, CD8, CD56) and intracytoplasmatic activation markers (IL-2, IFN-γ, TNF-α) for flow cytometric detection of virus-specific T-cells. T-cells with intracytoplasmic expression of activation markers after stimulation with the virus antigen are HHV-6-specific T-cells. This indicated HHV-6 specific cellular immunity.~No more interventions in human except blood sampling, only basic research."
