ITGAX and infection: Similar patterns were also seen in the chronic model of mouse infection, where the populations of macrophages that correspond to alveolar macrophages (AMs); SSC-A+CD11c+ (Figures 4A, B), CD64+CD11c+ (Figure 4C), CD11chigh (Figure 4E), and SiglecFhigh (Figure 4D) were reduced in a somewhat non-significant manner in the cohort that received PRK treatment.
