A study on the treatment of rheumatoid arthritis with lipid nanoparticles containing mRNA encoding heat shock protein 10

In order to delay the progression of Rheumatoid Arthritis (RA) in patients, and to prevent further teratogenesis and irreversible bone erosion through drug intervention in the early stages of inflammation, this experiment used the mRNA encoding heat shock protein 10 (HSP10) (H-mRNA) as the main therapeutic drug and used Microfluidics technology to prepare lipid nanoparticles (LNP) (H-mRNA LNPs) containing H-mRNA, and the surface of H-mRNA-LNPs was modified using heparin particals to obtain the final formulation H-mRNALNPs @ heparin/ Protamine. Through the sequence modification and effect evaluation of H-mRNA, we explored the formulation screening, physical characterization, cytotoxicity in vitro, distribution in vivo, pharmacodynamics in vivo, and safety in vivo of the prepared lipid nanoparticles, which proved that this nanopreparation had good anti Rheumatoid Arthritis effects, and conducted a preliminary exploration for the application of nucleic acid drugs in the treatment of diseases outside of tumors. This research would provide new ideas for the treatment of RA. (c) 2024 American Pharmacists Association. Published by Elsevier Inc.
