  • Abstract
  • Look Inside

 In order to elucidate the pathogenetic mechanism of HTLV-I M, we have established virus producing T-cell lines from peripheral blood and CSF mononuclear cells of 25 patients with HT-LV-I M. All cell lines were positively stained with HTLV-I M sera, ATL sera, and monoclonal antibodies to HTLV-I gag proteins, P15, P19 and P24, and revealed type C viral particles by electron microscopic studies. Cytofluorographic analysis showed most of the line cells T3+, T4+, 2H4+, T8+, T11+, Tac+, (IL-2R+) Ia+ helper inducer surface markers. By the restriction map analysis, we have found two major subgroups of HTLV-I, the MT-2 type and ATK-1 type. They were almost equally distributed among the HTLV-I M patients and ATL patients. Two subgroups of HTLV-I seem to ability to cause either two diseases, ATL or HTLV-I M.
