| Research Abstract |
Our previous studies suggested that immunological approaches to activate HTLV-I-specific T-cell response potentially induce prophylactic and therapeutic effects on ATL. In order to verify this notion and apply for bedside, we indicated that vaccination reduced proviral load in a rat model, and that a subpopulation of HTLV-I-carriers showed weak HTLV-I-specific T-cell response and elevated proviral load. Moreover, we discovered an innate immune-mediated mechanism suppressing HTLV-I expression in vivo.
