 AB    We tested for HTLV-I proviral DNA in skeletal muscle from patients with
       polymyositis infected with HTLV-I using the in situ polymerase chain
       reaction. We found the HTLV-I provirus in some of the CD4-positive cells
       in HTLV-I-positive polymyositis cases but not in HTLV-I-negative
       polymyositis ones. We could not detect HTLV-I within the muscle fibers.
       We suggest that HTLV-I-associated polymyositis is not due to direct,
       persistent infection of the muscle fiber by the virus, but to a
       T-cell-mediated immunological process triggered by the HTLV-I-infected
       cells.
