Interaction of prostaglandin E1 with human high density lipoproteins

AbstractProstaglandin E1 has been shown to interact with serum high density lipoproteins (HDL) in a manner resembling the interaction of a ligand with a high affinity binding site. The presence of 10−12–10−10 M prostaglandin E1 induces a rearrangement of the HDL surface lipids and probably influences the biological functions of the lipoproteins.Fluorescent phospholipid probeHigh density lipoproteinProstaglandin E
