Absolute numbers of cytokine-producing T cells from Salmonella-immunized mice after restimulation with Salmonella lysate^a

Organ	No. of CD4+ T cells producing cytokine		No. of CD8+ T cells producing cytokine
	IFN-γ	TNF-α	IFN-γ	TNF-α
Spleenb	(3.1 ± 1.7) × 105	(1.1 ± 5.4) × 105	(5.8 ± 3.2) × 105	(6.7 ± 4.0) × 103
Liverc	2.4 × 103	6.5 × 102	5.0 × 102	37
Bloodd	2.6 × 102	2.9 × 102	70	7.3
MLNe	(5.6 ± 3.2) × 103	(1.9 ± 1.4) × 103	(3.1 ± 2.8) × 104	(3.8 ± 5.0) × 102

^aMice were orally immunized ≥15 weeks earlier with Salmonella, and cytokine production was assessed after restimulation with Salmonella lysate. The absolute numbers of cytokine-producing T cells in the indicated organs are shown and are expressed as mean values ± standard deviations.

^bn = 7.

^cCells were pooled from five mice. Values represent an estimate of the total number of cytokine-producing T cells per mouse.

^dCells were pooled from four mice. Values represent an estimate of the total number of cytokine-producing T cells per mouse.

^eCells were pooled from six mice into three groups. Values represent an estimate of the total number of cytokine-producing T cells per mouse.
