Biomimicry of surfactant protein C.
Since the widespread use of exogenous lung surfactant to treat neonatal respiratory distress syndrome, premature infant survival and respiratory morbidity have dramatically improved. Despite the effectiveness of the animal-derived surfactant preparations, there still remain some concerns and difficulties associated with their use. This has prompted investigation into the creation of synthetic s...
متن کاملBiophysical activity of an artificial surfactant containing an analogue of surfactant protein (SP)-C and native SP-B.
Natural surfactant preparations containing phospholipids and the hydrophobic surfactant proteins B and C (SP-B and SP-C) are effective in the treatment of respiratory distress syndrome in premature infants. The limited supply, and the risk of infectious agents and immunological reactions have promoted the evaluation of synthetic peptides in surfactant preparations. However, the folding of synth...
متن کاملSuperficial disposition of the N-terminal region of the surfactant protein SP-C and the absence of specific SP-B-SP-C interactions in phospholipid bilayers.
A dansylated form of porcine surfactant-associated protein C (Dns-SP-C), bearing a single dansyl group at its N-terminal end, has been used to characterize the lipid-protein and protein-protein interactions of SP-C reconstituted in phospholipid bilayers, using fluorescence spectroscopy. The fluorescence emission spectrum of Dns-SP-C in phospholipid bilayers is similar to the spectrum of dansyl-...
متن کاملLocalization of surfactant-associated protein C (SP-C) mRNA in fetal rabbit lung tissue by in situ hybridization.
Surfactant is a lipoprotein substance that is synthesized and secreted by alveolar type II epithelial cells and acts to reduce surface tension at the air-alveolar interface. SP-C is a 5,000-D molecular weight, hydrophobic, surfactant-associated protein. In the present study, we used a ribonuclease protection assay to show that SP-C mRNA is induced in rabbit fetal lung tissue early in developmen...
متن کاملTwo SP-C genes encoding human pulmonary surfactant proteolipid.
Human pulmonary surfactant proteolipid of Mr = 5,000, now termed surfactant protein C (SP-C), is produced by proteolytic processing of an Mr = 22,000 precursor. The active hydrophobic peptide imparts surface active properties to pulmonary surfactant phospholipids. We have determined the entire nucleotide sequence of two distinct genes encoding SP-C from a genomic library prepared from human leu...
