 AB    Autopsy specimens from 3 patients with human T-lymphotropic virus
       (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP)
       were examined for the presence of HTLV-I in the central nervous system
       (CNS). In situ hybridization using an HTLV-I tax RNA probe detected
       cells containing HTLV-I RNA in spinal cord and cerebellar sections.
       HTLV-I infected cells were located within the white matter and, in
       particular, within the anterior and lateral funiculi of the spinal cord.
       Consistent with previously described HAM/TSP pathology, there were
       perivascular infiltrates in these CNS specimens. Significantly, HTLV-I
       RNA was not localized to these infiltrates but was detected deeper
       within the neural tissue. Furthermore, phenotypic analysis demonstrated
       that at least some of the infected cells were astrocytes. While previous
       polymerase chain reaction studies have demonstrated the presence of
       proviral HTLV-I in CNS specimens, here we provide evidence for the in
       situ expression of HTLV-I RNA in the CNS of HAM/TSP patients.
