摘要
The hyperplasia and destruction of synovial tissue have an important impact on the development of rheumatoid arthritis(RA), the abnormal proliferation and migration of synovial fibroblast in synovial tissue is similar to tumor cells. Targeting anomalous synovial fibroblast and designing a high bioavailability nano drug delivery system can reduce the dosage for the treatment of rheumatoid arthritis and it is of great significance to reduce toxic and side effects and improve curative effect. In this experiment, the nobiletin-loaded tetrahedral framework nucleic acids cargo tank was established, carrying antiinflammatory small molecule monomer drug nobiletin with minimal bioavailability. Both in vitro cell experiments and in vivo animal studies proved the nano cargo tank enhance the role of nobiletin in reducing the invasiveness of pathological synovial fibroblast and promote their apoptosis, effectively alleviate the disease development of rheumatoid arthritis.
