[Apolipoprotein B of plasma lipoproteins incorporated in liposomes: immunological properties and organ distribution when administered to rabbits].

Apolipoprotein B (apo B) isolated from low density lipoproteins (LDL) was built in phospholipid-cholesterol liposomes, with the lipid/protein ratio being equal to 33:1. Such liposomes preserved their integrity, whereas the constituent apo B retained its antigenic properties. After intravenous injection to rabbits the pattern of apo B liposome distribution among organs was similar to that of LDL. Apo B liposomes may be used for goal-oriented transport of some substances to organs and tissues whose cells have specific receptors for apo B-containing lipoproteins.
