Increased lung IL-4 expression in pulmonary fibrosis suggests a potential pathogenetic role for this cytokine. To dissect this role, bleomycin-induced pulmonary inflammation and fibrosis were analyzed and compared in wild type (IL-4(+/+)) vs IL-4-deficient (IL-4(-/-)) mice. Lethal pulmonary injury after bleomycin treatment was higher in IL-4(-/-) vs(More)
Leukocyte infiltration is characteristic of lung injury and fibrosis, and its role during tissue repair and fibrosis is incompletely understood. We found that overexpression of IL-5 in transgenic mice (IL-5(TG)) or by adenoviral gene transfer increased bleomycin (blm)-induced lung injury, fibrosis, and eosinophilia. Surprisingly, blm-treated IL-5-deficient(More)
