REVIEW
Nandhakumar Sathyamoorthy, Magharla Dasaratha Dhanaraju
The mononuclear phagocyte system (MPS) defends the body against the invasion of microorganisms by phagocytosis. In the presence of opsonins, the invading matter is readily recognized by phagocytes because of the interaction between receptors on the phagocytic cell surfaces and the modified conformation of opsonins. The particulate carriers, which are otherwise capable of optimizing drug delivery, are subjected to opsonization and phagocytosis by the MPS immediately following intravenous administration. These drug carriers should remain in the bloodstream in order to spatially locate the drug to the target site and temporally control the drug's release from there on; however, they are devastated by opsonization by serum proteins...
