In order to investigate whether distinct subpopulations of newly recruited host phagocytes were preferentially infected upon arrival at the site of infection, we compared CD11c and F4/80 expression on infected and non-infected newly recruited cells (CD45.1+) and recipient cells (CD45.2+) expected to be, on average, present at the infection site for a longer time period before analysis (Fig 8A–8C). This evidence concerns the gene ITGAX and infection.
