Research Abstract

The etiological factor(s) of rheumatoid arthritis (RA) have been well unknown.
The salient features is invasive synovial proliferation lead to bone erosion.
We have revealed the relationship of the HTLV-I infection to chronic arthropathy through out the study of clinical and molecular biological analysis and established the following results.
1) The patient with arthropathy in HTLV-I infection was proposed as one of the subsets of RA.
2) The presence and the expression of proviral HTLV-I genome in synovial cell derived from HAAP patient were clarified.
3) HTLV-I tax expression causes synovial transformation and hyperplasia in either human synovial or transgenic mice. Therefore, we demonstrate that HTLV-I tax gene is the first exogeneous retroviral gene which causes resembling rheumatoid arthritis.
