Drug delivery targets and systems for targeted treatment of rheumatoid arthritis

Abstract

Rheumatoid arthritis (RA) is an immune-mediated inflammatory disease that selectively attacks human joints. The common non-targeted treatment approaches lead to obvious side effect and systemtic complication for RA patients. Therefore, targeted drug delivery for treatment of RA has gained much attetntion in the past few years. In this paper, we reviewed the potential targets (folate receptor, angiogenesis, matrix metalloproteases, selectins, vasoactive intestinal peptide receptor andFc-γ receptor) that could be utilised to facilitate the specific delivery of drugs to the inflammed synovium and also presented different drug delivery systems for targeting RA, including the liposomes, various types of nanoparticles, polymeric micelles and the macromolecular prodrugs. The strategies combining nanotechnologies and ligand mediated active targeting for RA would be emphatically illustrated, which was expected to be helpful for identifying technologies and drug delivery methods for targeted treatment of RA.
