FCGR1A and infection: At 36 hours post-A. fumigatus challenge, we observed equivalent numbers of total lung cells, neutrophils (Ly6G+ CD11b+), monocytes (CD11bhi CD64− major histocompatibility complex class II [MHC-II]−), and type 2 conventional dendritic cells (cDC2s) (CD103− CD11b+) in both the A. fumigatus-only infection and IAV-Af superinfection groups that were increased compared to the those of the PBS control and IAV single-infection groups (Fig. 2A, B, E, and G).
