immune system
abnormal mast cell differentiation ( J:142880 )
• synovial mast cells do not express the mMcp-6 and -7 proteases
decreased susceptibility to induced arthritis ( J:142880 )
• there is a signifcant decrease in clinical measurements of joint inflammation induced by Tg(TcraR28,TcrbR28)KRNDim (i.e. K/BxN) mouse serum compared to C57BL/6 controls
• ankle thickness is also less than controls 10 days after arthritis induction
• histological scores of bone and cartilage erosion, as well as inflammation, are also significantly reduced
