Lymphocytic ILDs decrease and neutrophilic ILDs increase with aging. (A) Mean values of leukocyte subset in bronchoalveolar lavage (BAL) of individuals without pulmonary pathology; (B) mean BAL lymphocyte and neutrophil values in patients with different types of interstitial lung disease (ILD); (C) mean values of macrophages, lymphocytes, neutrophils, eosinophils, and CD1a+ Langerhans cells in the BAL of total ILD patients according to age, at <55, 55–65, and >65 years; and (D) proportion of patients with lymphocytic (lymphocytes > 20%), neutrophilic (neutrophils > 10%), eosinophilic (eosinophils > 3%), and Langerhans cells (>1.5%) profiles, for patients aged <55, 55–65, and >65. ***, indicate p < 0.001 in the ANOVA test.
