Neutrophils and macrophages are less abundant in the lungs of IL-1 receptor-deficient mice during A. fumigatus airway infection. Total pulmonary neutrophils, alveolar macrophages, lymphocytes, and eosinophils were determined by flow cytometry analysis of C57BL/6 and IL-1R1^-/- collagenase digested lungs of the indicated mouse strains 3 days after infection with A. fumigatus beads. Results represent means ± SEM of groups of n > 15 mice across 2 experiments, **p < 0.01, ***p ≤ 0.001 (Student’s t-test).
