Bleomycin toxicity affects which type of cells :
Type–I pneumocytes
Type–II pneumocytes
Endothelial cells
Pulmonary alveolar macrophages
Bleomycin causes necrosis of Type I pneumocytes that results in compensatory hyperplasia of type-II pneumocytes. The same kind of injury can also occur in response to radiations. In experimental models, this type of injury has been ameliorated by keratinocyte growth factor.
