AB The immunopathology of human T cell lymphotropic virus type 1 (HTLV-I)
uveitis was addressed by using T cell clones (TCC) established from the
intraocular fluid of patients with HTLV-I uveitis. Proviral DNA of
HTLV-I was identified in 55 out of 94 (59%) or 13 out of 36 (36%) TCC
from the ocular fluid or the peripheral blood of these patients,
respectively. Most of HTLV-I-infected TCC had a CD3+ CD4+ CD8-
phenotype. HTLV-I infection on TCC was confirmed by analysis of the
viral mRNA, nucleotide sequence, virus-associated proteins, and virus
particles. HTLV-I-infected TCC, but not HTLV-I negative TCC,
constitutively produced high amounts of IL-6 (1,336 +/- 1,050 pg/ml) and
TNF-alpha (289 +/- 237 pg/ml) in the absence of any stimuli.
HTLV-I-infected TCC from the ocular lesion also constitutively produced
high amounts of IL-1 alpha (12,699 pg/ml), IL-2 (61 pg/ml), IL-3 (428
pg/ml), IL-8 (1,268 pg/ml), IL-10 (28 pg/ml), IFN-gamma (5,095 pg/ml),
and GM-CSF (2,886 pg/ml). Hydrocortisone, a drug effective in vivo for
the treatment of HTLV-I uveitis, severely depressed cytokine production
in vitro in most cases. In summary, the results demonstrated direct
evidence of HTLV-I infection of the eye and suggest that cytokines
produced by HTLV-I-infected T cells are responsible for the intraocular
inflammation in patients with HTLV-I uveitis.
