At later timepoints, the immune response was dominated by eosinophilia, observed both in the airways (BAL) (Figure 1E) and the lung (Figure 1F) at d7 p.i. Increased eosinophil numbers corresponded to a type 2 immune response, which is critical for tissue repair [32, 38], and was associated with a fivefold increase in IL‐13 concentration in the lungs (Figure 1G). The gene discussed is IL13; the disease is Increased total eosinophil count.
