Interactions of Lipid Vesicles with Blood Proteins and Platelets.
Abstract
The interactions of hemoglobin containing liposomes and of liposomes composed of polymerizable phospholipids with blood cells and proteins have been examined. All types of liposomes studied bound a variety of serum proteins with IgG being the most abundant component in each case. Polymerized methacrylate liposomes specifically bound a 53 kilodalton protein not bound by other liposome types. None of the liposomes tested provoked platelet aggregation; however, unpolymerized methacrylate liposomes markedly inhibited ADP induced platelet aggregation. Most liposomes tested did not affect clotting of plasma; however polymerized methacrylate liposomes bound clotting factor V and thus inhibited clotting.
