Blockade of IL-10R partially alters lung inflammation in T. muris-infected Rag1−/− mice following papain challenge. (A) Time course of low-dose infection with T. muris and blockade of IL-10R. (B) Total bronchoalveolar lavage (BAL) fluid cell, BAL fluid eosinophil, and BAL fluid neutrophil counts. (C) PAS-stained sections of lungs, visualized using ×20 magnification. Data are means ± SEM, pooled from 2 independent experiments (n = 6 to 8 mice per group) (B and C). Sections are representative of 2 independent experiments (C). Ctrl, control; Tm, T. muris infected.
