| Research Abstract |
Th1 activation based on high HTLV-I proviral load plays an important role in the development of HTLV-I-associated myelopathy (HAM). In order to elucidate the cell signaling pathway involved in this situation, we analyzed the relationship between the expression of IFN-γ and HTLV-I and IL-2 receptor (IL-2R)/p38 MAPK signaling. At first, we demonstrated that activation of p38 MAPK signaling is involved in this situation. Secondly, the importance of IL-2/IL-2R signaling located in the upstream of p38 MAPK was suggested for IFN-γ and HTLV-I expression. Overall, our results indicate that IL-2R/p38 MAPK signaling pathway may be a potential target in therapeutic strategies for HAM.
