title: [Lymphocyte subsets and interleukin-2 (IL-2) production of peripheral blood lymphocytes in patients with Vogt-Koyanagi-Harada disease].
abstract: The lymphocyte subsets and the interleukin-2 (IL-2) production of peripheral blood lymphocytes (PBL) in patients with Vogt-Koyanagi-Harada Disease (V.K.H.) were studied. In PBL, increased percentages of CD4+ T cells and decreased percentages of CD8+ T cells, which lead to high CD4/CD8 ratio were observed. In the CD4+ T cells the percentage of CD4+ 2H4+ T cells and CD4+ DR+ T cells increased. PBL from 3 out of 9 cases with V.K.H. produced high amount of IL-2 in vitro after stimulation with PHA, indicating IL-2 might be related to the pathogenesis of V.K.H. The differences of the phenotypes of PBL and IL-2 production in vitro between the patients in the acute and prolonged stages were not demonstrated. These results suggest that CD4+ T cells, especially CD4+ 2H4+ T cells may play an important role in the pathological feature of V.K.H.
