 AB    Immunocytochemical staining of spinal cords from five autopsied patients
       with HTLV-I-associated myelopathy/tropical spastic paraparesis was
       performed using a panel of monoclonal or polyclonal antibodies reactive
       with interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor
       necrosis factor (TNF)-alpha, interferon (IFN)-alpha, IFN-beta, IFN-gamma
       and transforming growth factor (TGF)-beta. In the spinal cords of
       patients with a shorter duration of illness, IL-1 beta, TNF-alpha, and
       IFN-gamma were expressed on perivascular infiltrating macrophages,
       astrocytes and microglia in active-chronic inflammatory lesions. In
       striking contrast, we rarely noted cytokine expression except for
       IFN-gamma in inactive-chronic lesions of patients with longer durations.
       In situ expression of these cytokines on microglia and astrocytes, in
       addition to infiltrating mononuclear cells, suggests that glial cells
       participate in the inflammatory process, especially in active lesions.
       In addition, the cytokine expression was gradually downregulated along
       with duration of illness.
