Effects of calcium and calmodulin inhibitors on the abnormal proliferation of lung fibroblast.
The effects of alveolar macrophage (Am phi) conditioned media from interstitial lung disease (ILD) patients on fibroblast (FB), and the role of calcium (Ca2+) blockers and calmodulin (CaM) inhibitors on the proliferation of lung FB were studied. We found that the AM phi conditioned media could stimulate FB cell proliferation and this effect could be abolished by Ca2+ blockers and CaM inhibitors. The results indicated that AM phi was in activated state in ILD and released some kinds of cytokines to stimulate the proliferation of FB, and Ca,2+ CaM were partially responsible for these actions.
