title: Bauhinia purpurea lectin (BPA) binding of rat type I pneumocytes: alveolar epithelial alterations after radiation-induced lung injury.
abstract: In the rat lung, we found that the Bauhinia purpurea lectin (BPA) specifically binds to the type I alveolar epithelial cells and to the alveolar macrophages. Double label fluorescence employing FITC-coupled Maclura pomifera lectin (MPA) and bBPA-avidin-Texas Red showed that BPA binding was confined to type I cells. In addition, a minor staining of the luminal border of the terminal bronchiolar epithelium was found. The sequence of tissue injury following X-radiation was examined in rats. BPA is a suitable marker which indicates epithelial changes during the early stage of pneumonitis and the subsequent development of fibrosis.
