CD68 and allergic disease: While significantly fewer Iba1+ cells also expressed MHCII in allergic mice (control: 7172 ± 913 cells/mm3, allergy: 5555 ± 766 cells/mm3; p < 0.0001; Figure 3D), there was no change in the numbers of Iba1+CD68+ cells (control: 10103 ± 609 cells/mm3, allergy: 10300 ± 1002 cells/mm3; p < 0.6345; Figure 3E).
