Percentage and absolute numbers of IFNγ-producing cells in different lymphocyte subsets in peripheral blood from ten healthy adults following stimulation with Salmonella.

For each lymphocyte subset in the peripheral blood of each subject, the absolute concentration of cells (Count; cells/µl), percentage of IFNγ-producing cells (%IFNγ+) and absolute numbers of IFNγ-producing cells (IFNγ+ Count; cells/µl) following stimulation for six hours with live S. Typhimurium D23580 were determined by intracellular cytokine staining and a hematological analyzer. All adaptive lymphocytes (Acq lymph; CD4+-and CD8+-T cells), innate lymphocytes (Innate lymp; γδ-T cells, NK cells and NK-like T cells), together with total numbers of IFNγ-producing lymphocytes are shown in the right-hand columns. Geometric means are for average percentages and absolute numbers of cells across all subjects.
