[The effect of cholesterol level in liposomes on the interaction with blood serum lipoproteins].
The effect of the cholesterol content in liposomes on their interaction with blood serum lipoproteins has been studied. It was shown that phosphatidyl choline liposomes without cholesterol did not interact selectively with any class of serum lipoproteins. At the same time, addition of high cholesterol concentrations to liposomes confers to them a new feature, namely the ability to interact selectively with the serum low density lipoproteins. Up to 90% of such lipoproteins can interact with liposomes. This finding was confirmed by "in vivo" data. The observed effect of "address" properties given to liposomes by a native lipid may be of interest in search for new possibilities to use liposomes for selective delivery of drugs.
