Expression of I-A^d/I-E^d molecules on F4/80⁺ or CD11b⁺ spleen cells from normal uninfected mice and from infected mice treated with NRG or anti-IL-12 antibodies

Mouse group	Mean fluorescence intensity (FL2) of I-Ad/I-Ed ona:
	F4/80+ cells		CD11b+ cells
	Day 7	Day 13	Day 7	Day 13
Normal	91 ± 13	82 ± 5	24 ± 2	20 ± 1
NRG treated	750 ± 50	1,163 ± 233	421 ± 45	615 ± 76
Anti-IL-12 treated	146 ± 13	75 ± 16	61 ± 7	19 ± 9

^aF4/80⁺ or CD11b⁺ cells were gated by using FL1. The results are expressed as the geometric means of fluorescence intensity (FL2). The data represent the means ± standard deviations of three similar experiments. The geometric mean of fluorescence intensity when staining with the conjugated isotype control antibodies was less than 10 for all three groups of mice.
