In addition, higher numbers of F4/80-CD11b-CD11c+Siglec-H+PDCA-1+ DCs (pDCs) (p < 0.001 at 28, 56 and 112 days post-infection) and CD11c-CD11b+Gr-1int cells (p < 0.05 at 56 and 112 days post-infection) were observed in a time-dependent manner only in the lungs of mice that were infected with Mtb K (Fig 3B). Here, ITGAX is linked to infection.
