Abstract

PURPOSE. To better define the role of lymphocytes in the pathogenesis of uveitis, we studied the expression of memory and naive cell markers on T lymphocytes from peripheral blood. METHODS. Surface antigens on T lymphocytes obtained from peripheral blood of 27 patients with uveitis, including 12 patients with Behçet's disease (BD), 7 patients with Vogt-Koyanagi-Harada disease (VKH), and 8 patients with idiopathic uveitis (IU), were detected by three-color flow cytometric analysis. Lymphocytes from 14 age-matched healthy control subjects were similarly evaluated. RESULTS. The percentage of T lymphocytes that were CD4 + CD29 + lymphocytes (memory cells) was high in all patients with uveitis, while that of CD4 + CD45RA + lymphocytes (naive cells) was lower in patients with BD and VKH, although the difference was not statistically significant. The percentage of CD29 + cells within CD3 + CD4 + cell population was significantly higher in patients with BD and VKH than in the controls (p < 0.01), and the percentage of CD45RA + cells was significantly lower in BD patients than in controls (p < 0.01). The T lymphocyte subsets in patients with IU were similar to the controls. CONCLUSIONS. These results show an abnormal distribution of T lymphocytes in patients with uveitis associated with an underlying systemic disease.
