Research Abstract |
Current research aimed to develop a new multifunctional nano-probes for diagnosis and treatment of osteoarthritis, which will increase according to the acceleration of demographic aging. We could demonstrate the effect of cartilage-specific contrast agent, octaarginine peptide conjugated with DOTA-Gd, in ex vivo and in vivo experiments of rabbit knee joints. While R8-N-TIMP3, designed as a cartilage protective agent, did not show sufficient protective effect in a mouse model of rheumatoid arthritis although it showed in ex vivo tissue culture experiments. Further study is necessary after a prolonged expression of R8-NTIMP-3 in the arthritic knee joints.
