Outline of Final Research Achievements

The aim of this study is to reveal the character of chondroclasts in rheumatoid arthritis (RA), so-called from the location near cartilage. The analysis using tissue from RA patients revealed that chondroclasts produce the enzymes which degrade extra cellular matrix of cartilage. The analysis of cultured cells revealed that a particular cytokine induce the differentiation into chondroclasts. Thus, it is suggested that chondroclasts are involved in cartilage degradation and joint destruction in RA patients.
