The total CD11b+ population displayed a similar trend in WT and Δisp2/3-infected ears, with comparable percentages of CD11b+ cells during the 5 wk of infection (Supplemental Fig. 3A), and a significantly higher total number of CD11b+ cells in Δisp2/3 infections at 2 d only (Supplemental Fig. 3B). Here, ITGAM is linked to infection.
