Clinical Validation of a Novel Elispot-Based Diagnostic Assay: Monitoring Cytomegalovirus-Specific Cell-Mediated Immunity and Risk Stratification in …
2019
Increasing evidence suggests that impaired cytomegalovirus (CMV)-specific cell-mediated immunity (CMV-CMI) is a major cause of uncontrolled CMV reactivations and associated complications in hematopoietic stem cell transplantation (HSCT). No reliable test exists to predict patients at risk of primary and/or recurrent CMV reactivations following HSCT. Accurately assessing CMV-CMI might therefore improve the risk stratification of patients and allow optimizing and individualizing patient care. This study aimed to evaluate the suitability of a novel IFN-γ ELISpot assay (T-Track® CMV), based on the stimulation of peripheral blood mononuclear cells with T-activated® pp65 and IE-1 CMV proteins, to…
Frequency of CD8+ T Lymphocytes Specific for Lytic and Latent Antigens of Epstein–Barr Virus in Healthy Virus Carriers
1999
Abstract We investigated CD8 + T cell frequencies of five different Epstein–Barr virus-specific cytotoxic T lymphocyte epitopes located within proteins of the replicative cycle and the latent state in healthy long-term virus carriers with IFN-γ enzyme-linked immunospot assay. Frequencies of the HLA-A3-restricted epitope RVRAYTYSK (RVR) whose minimal length was mapped in this study to amino acid position 148–156 of the immediate-early protein BRLF1 were compared with those of a further known HLA-A3-restricted epitope within EBNA3A, RLRAEAQVK (RLR). Determination of frequencies of CD8 + T lymphocytes directed against lytic antigen epitope RVR revealed that only one of eight donors recognized …
