Proteins of human bronchoalveolar lavage fluids, obtained by washing the epithelial lining fluid of the lungs with phosphate-buffered saline, were analyzed by two-dimensional electrophoresis under denaturating and reducing conditions. The two-dimensional pattern of bronchoalveolar lavage fluid proteins of healthy volunteers (controls) were compared with those of patients with idiopathic pulmonary fibrosis, sarcoidosis, and asbestosis. Particular interest was paid to the proteins present in minor amounts mainly in the low molecular weight region of the gels. Marked changes in single protein spots were observed. In idiopathic pulmonary fibrosis the spot intensity of the surfactant-associated protein, SP-A, showing isomeric forms both in charge and in molecular weight, was markedly decreased. In sarcoidosis, the immunoglobulins (IgG, IgA) and a group of protein spots at an isoelectric point of 4.5-5.0 and a molecular mass of 55 kDa were increased. An additional spot appeared at an isoelectric point of 4.5 and a molecular mass of 12 kDa. In particular in asbestosis, but also in some cases of idiopathic pulmonary fibrosis and sarcoidosis, the number and intensity of low molecular weight proteins were increased strongly.
