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

<p>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 <i>S</i>. 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.
