Reconstitution of cardiac gap junction channeling activity into liposomes : a functional assay for gap junctions. Reconstitution of gap junction channels : liposomes as tools to assay the activity of channel-forming proteins. However, phospholipid liposomes have some limitations, such as sensitivity to phospholipases, high cost of manufacture and difficulty in scale-up for production. The liposomes were then fused with planar bilayers for direct examination of single-channel properties. It was mentioned above that conventional liposomes act as non-toxic vesicles for an insoluble drug, releasing it slowly back to the circulation. It is possible that in cells glucan liberated from liposomes directly stimulates effector macrophage functions. In this respect, the administration of benzimidazole carbamate anthelmintics in stabilized liposomes provides sustained drug-release reservoirs and considerably enhances their bioavailability. In agreement with this hypothesis was our finding that empty liposomes did not modify collagen content except for on the last day of the experiment. Two liposomes are docked to the bilayer in the view field as indicated by the synaptobrevin dyes. Cationic lipids are highly soluble in aqueous solution, forming positively charged micellar structures termed liposomes. Endocytosis of poly(ethylene oxide)-modified liposome by human lymphoblastoid cells. Purified prion proteins and scrapie infectivity copartition into liposomes. In addition, no other protein was present in sufficient amounts to account for the number of permeable liposomes. Addition of liposomes to the free drug made very little difference to the clearance.
