Healthy controls (HC) demographics and NLV expansion profiles.

HLA class I typing, CMV serology status and NLV-specific T cell expansion profiles of healthy individuals. Molecular resolution of HLA class I antigens was available as indicated (4-digit). In vitro T cell cultures were derived by autologous stimulation of PBMC with NLV peptide (1 µM) for 13 days in the presence of IL-2 (20 U/ml). Percentages of A2/NLV-tetramer+ T cells were based on the total CD8+ T cell population. HC1 and 2 were excluded from the average, SD and range calculations.Abbreviation: not tested (NT).
