1 Interaction of pulmonary surfactant protein A with dipalmitoylphosphatidylcholine and cholesterol at the air/water interface. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
2 Interaction of pulmonary surfactant protein A (SP-A) with pure and binary mixed dipalmitoylphosphatidylcholine (DPPC) and cholesterol (3.5 wt%) at the air/saline, 1.5 mM CaCl2 interface was investigated using a rhomboid surface balance at 37 degrees C. Surface tension-area isotherms were measured to access the surface active properties of the monolayers. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
3 Interaction of pulmonary surfactant protein A (SP-A) with pure and binary mixed dipalmitoylphosphatidylcholine (DPPC) and cholesterol (3.5 wt%) at the air/saline, 1.5 mM CaCl2 interface was investigated using a rhomboid surface balance at 37 degrees C. Surface tension-area isotherms were measured to access the surface active properties of the monolayers. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
4 The results showed that SP-A can interact with the polar head groups of DPPC monolayers and aggregate DPPC molecules. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
5 The results showed that SP-A can interact with the polar head groups of DPPC monolayers and aggregate DPPC molecules. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
6 SP-A decreased the surface area reduction required for DPPC monolayers to achieve near zero surface tension from 30 to 25% of the area at equilibrium. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
7 Although SP-A could not promote the squeeze-out of cholesterol from homogeneous mixed monolayers, it facilitated that of cholesterol domains especially when SP-A had first interacted with DPPC. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
8 These results indicate that pulmonary surfactant protein A facilitates the squeeze-out of cholesterol domains from mixed monolayers by condensing DPPC and limiting lateral interactions of DPPC with cholesterol domains. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
9 These results indicate that pulmonary surfactant protein A facilitates the squeeze-out of cholesterol domains from mixed monolayers by condensing DPPC and limiting lateral interactions of DPPC with cholesterol domains. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
