Inhalation of Stachybotrys chartarum Fragments Induces Pulmonary Arterial Remodeling.

abstract：:Hypersensitivity pneumonitis (HP) is an allergic granulomatous interstitial lung disease resulting from a reaction of selected individuals to repeated inhalations of certain antigens. HP is characterized by chronic inflammation, and the development of the disease seems to be immunologically mediated. In farmer's lung,...
