title: [The role of endothelin-1 and tumor necrosis factor-alpha in the development of asthma sarcoidosis].
abstract: In order to investigate the interaction of endothelin-1 (ET-1) and tumor necrosis factor-alpha (TNF-alpha) and their activity in the pathogenesis of asthma, ET-1 plasma and BALF levels were measured, and the amount of TNF-alpha released from alveolar macrophage (AM) was also tested. As in vitro the airway smooth muscle cells were stimulated with TNF-Alpha, the release of ET-1 was also observed. The results showed that the amount of ET-1, TNF-alpha were both increased than in the control group, at the same time, TNF-alpha could stimulate smooth muscle cells to secrete ET-1. We concluded that the release of ET-1 induced by TNF-alpha might play a certain role in development of airway hyperresponsiveness and airway remodeling.
