Study Data from Massachusetts General Hospital Provide New Insights into Rheumatoid Arthritis (Hyaluronate-Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis)

By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators discuss new findings in Autoimmune Diseases. According to news originating from Cambridge, Massachusetts, by NewsRx correspondents, research stated, "Rheumatoid arthritis (RA) is a chronic inflammatory immune disease causing the inflammation of synovial membrane and the articular cartilage destruction. In this work, hyaluronate gold nanoparticle/Tocilizumab (HA-AuNP/TCZ) complex was prepared for the treatment of RA."

Our news journalists obtained a quote from the research from Massachusetts General Hospital, "AuNP was used as a drug carrier with antiangiogenic effect. in is a humanized monoclonal antibody against the interleukin-6 (IL-6) receptor and used as an immunosuppressive drug by Interfering IL-6 in the pathogenesis of RA. HA is known to have cartilage-protective and lubricant effects. HA was modified with cystamine via reductive amination, which was reduced with dithiothreitol (DTT) to prepare end-group thiolated HA (HA-SH). AuNP was chemically modified with HA-SH and physically modified with T. The formation of HA-AuNP/TCZ complex was corroborated by UV-vis spectroscopy, dynamic light scattering (DLS), and transmission electron microscopy (TEM)."

According to the news editors, the research concluded: "The therapeutic effect of HA-AuNP/TCZ complex on RA was confirmed In collagen-induced arthritis (CIA) model mice by ELISA, histological, and Western blot analyses."
