AB In HTLV-I-associated myelopathy or tropical spastic paraparesis
(HAM/TSP) immunopathological processes in the central nervous system
(CNS) have not been clarified. We compared the humoral and cellular
immunity within the CNS and in the systemic circulation of 24 patients
with HAM/TSP (8 men and 16 women) to 6 asymptomatic HTLV-I carriers, 7
patients with active multiple sclerosis, 6 patients with acute viral
encephalitis, and 39 patients with other non-inflammatory neurological
diseases. Significant differences were observed between the HAM/TSP
patients and one or more of the control groups: HAM/TSP cerebrospinal
fluids (CSF) exhibited higher levels of IgG, IgG index, de novo IgG
synthesis rate, and beta 2-microglobulin, and also a predominance of
CD8+ cells that expressed CD11a and CD45RO but lacked CD28 antigens.
Results in the 6 patients with acute viral encephalitis suggested that
the CD8+ population in the CSF which is positive for CD28 and CD45RO is
important for the elimination of virus from infected CNS tissues.
Therefore, potentially cytotoxic T cells of a unique
CD8+CD11a+CD45RO+CD28- phenotype may play a key role in the CNS
pathogenesis of HAM/TSP.
