Figure 4. IFNγ production by lymphocyte subsets in response to stimulation with live and heat-killed Salmonella.
Percentages of IFNγ-producing lymphocyte subsets in peripheral blood from ten healthy adults following 6 hours of stimulation with (A) live and (B) heat-killed S. Typhimurium D23580. Each dot corresponds to the percentages of IFNγ-producing cells in each lymphocyte subset in blood from one individual. CD3+CD4+: CD4+-T cells; CD3+CD8+: CD8+-T cells; CD3+TCRγδ+: γδ-T cells; CD3−CD56+: NK cells; CD3+CD56+: NK-like T cells.
