We observed an overall increase in human monocytes/Mφ (CD3-CD14+, especially the CD11c- monocyte subpopulation) in the bone marrow (where these cells are generated) and decreases in the both CD11c+ and CD11c- monocytes/Mφ subpopulations in the blood at 7 days post-infection. Here, ITGAX is linked to infection.
