Following the gating illustrated in Fig. 4 and selecting CD64+ cells, we identified infiltrating monocytes (MHCII−, Ly6C+), maturing monocytes (MHCII+, Ly6C+) and macrophages (MHCII+, Ly6C−) (Fig. 5A), illustrated in the ‘monocyte waterfall’ (Bain et al., 2013), at both day 7 and day 14 post infection. This evidence concerns the gene FCGR1A and infection.
