Figure 2. CSF1R is required for host defense in pneumonia.
Concentration of circulating monocytes (A) and lung mononuclear phagocytes (B) in uninfected mice after administration of daily CSF1R antibody or isotype control for 7 days using the gating strategy depicted in Figure 3A; n = 4–5 per group (* p < 0.05, Mann-Whitney). (C) Outcome of pneumonia in animals treated with anti-CSFR1 or isotype control Ab; n = 23–24 per group from 2 experiments (** p < 0.01, Log-rank test). (D) Bacterial burden in lungs of animals with pneumonia treated with anti-CSFR1 or isotype control Ab on day 3 of infection. Data from 2 experiments. Samples with no recoverable bacteria are depicted as 1 colony-forming unit. (* p < 0.05, Mann-Whitney).
