Cellular sources of IFN-γ secretion in response to autologous LCLs.
PBMCs from a healthy EBV-seropositive donor FT were sequentially fractionated into CD8+, CD4+, CD56+, and CD8−CD4−CD56−cell populations using CD8 and CD4 Dynal-beads and CD56 Microbeads. Each cell population was incubated with autologous LCL stimulators for the detection of IFN-γ secretion in an ELISPOT assay. Each bar represents the mean ± SD of triplicate wells. The numbers of spots/1 × 106 cells of the respective cell population are shown on the Y axis.
