Mice given ALI induced by Streptococcus pneumoniae (Sp) were studied 6 days after infection, a time point during resolution when infected mice have regained much of their weight loss (Gomez et al., 2017; Matute‐Bello et al., 2008) Mice lacking IFN‐γ had a similar weight loss and return to baseline weight by 6 days post‐Sp, compared to WT mice (Figure 2a). The gene discussed is IFNG; the disease is infection.
