1 Pulmonary surfactant protein A (SP-A) augments the uptake of phospholipid liposomes containing dipalmitoylphosphatidylcholine (DPPC) by alveolar type II cells. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
2 Pulmonary surfactant protein A (SP-A) augments the uptake of phospholipid liposomes containing dipalmitoylphosphatidylcholine (DPPC) by alveolar type II cells. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
3 Pulmonary surfactant protein A (SP-A) augments the uptake of phospholipid liposomes containing dipalmitoylphosphatidylcholine (DPPC) by alveolar type II cells. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
4 Pulmonary surfactant protein A (SP-A) augments the uptake of phospholipid liposomes containing dipalmitoylphosphatidylcholine (DPPC) by alveolar type II cells. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
5 SP-A increased the amount of liposomes containing radiolabeled DPPC associated with type II cell plasma membrane by 4-fold compared to the control without SP-A when analyzed by sucrose density gradient centrifugation. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
6 When type II cell plasma membrane and liposomes containing [14C]DPPC and [3H]triolein were coincubated with or without SP-A, analysis on sucrose density gradients revealed that the profiles of [14C]DPPC and [3H]triolein in each fraction were almost identical with or without SP-A, indicating that SP-A mediates the binding of liposomes to plasma membrane but not transfer of DPPC. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
7 When type II cell plasma membrane and liposomes containing [14C]DPPC and [3H]triolein were coincubated with or without SP-A, analysis on sucrose density gradients revealed that the profiles of [14C]DPPC and [3H]triolein in each fraction were almost identical with or without SP-A, indicating that SP-A mediates the binding of liposomes to plasma membrane but not transfer of DPPC. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
8 SP-A increased the association of liposomes containing DPPC with the membrane by 2-fold more than that containing 1-palmitoyl-2-linoleoyl-phosphatidylcholine (PLPC). 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
9 SP-A induced aggregation of phospholipid liposomes containing PLPC as well as those containing DPPC, but the final turbidity of DPPC liposomes aggregated by SP-A was only by 15% greater than that of PLPC liposomes. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
10 SP-A induced aggregation of phospholipid liposomes containing PLPC as well as those containing DPPC, but the final turbidity of DPPC liposomes aggregated by SP-A was only by 15% greater than that of PLPC liposomes. 1,2-Dipalmitoylphosphatidylcholine surfactant protein A1 Homo sapiens
